<br />
Just noting that Quality Chess' promised <a href="http://www.qualitychess.co.uk/products/1/124/the_king">book on the King's Gambit</a> is as elusive as ever. Now the <a href="http://www.qualitychess.co.uk/blog/?p=959">publishing date</a> is set to May (the discrepancy between the publishing schedule and the book's info page is normal).<br />
<br />
<br />
<br />
<br />
<br />
<br />
<strong><em>Update 2012-03-27</em></strong><br />
Now the blog says May/June while the book's info page says May. In one month the publishing date has only been delayed with half a month - looks like progress.<br />
<br />
<strong><em>Update 2012-05-21</em></strong> <br />
<br />
And now it's July. Not quite two months have passed and the delay is another month and a half... No new indications of progress. </div>Sverre Johnsenhttp://www.blogger.com/profile/00796086172553035906noreply@blogger.com9tag:blogger.com,1999:blog-4097677957983331811.post-66268563343906409012012-01-23T08:59:00.000+01:002012-01-24T08:28:23.538+01:00Killer Opening Repertoire Reviewed<div dir="ltr" style="text-align: left;" trbidi="on">

Today I received a newsletter from Chessville informing me that Bill McGeary has <a href="http://www.chessville.com/reviews/AKillerChessOpeningRepertoire.htm">reviewed "A Killer Chess Opening Repertoire</a>":<br />
<br />
The review is in general favourable and contains no big surprises. In my opinion the reviewer somewhat misses the mark when he writes: <br />
<em>"Another thing is that the book is dated. Certainly the material in this book is very good, but a number of the lines have evolved a great deal since the first edition. Johnsen writes that only six new games appear in this edition and only one was taken out, also that some games were expanded."</em> <br />
My objection is that the main updating went into the notes and not into the games selection. <a href="http://marshtowers.blogspot.com/2010/05/chess-reviews-139.html">Sean Marsh' review in Marsh Towers</a> comes closer to my point of view: <em>"Opening the book at random, I discovered an average of five post-1998 game references per double-page spread. Despite the outward appearance, showing (at first glance) the book to be more or less the same as the old edition, it is clear that Sverre has put a lot of work into creating this new edition, while keeping his footsteps very discrete."</em><br />
<br />
<br />
Anyway, the review is mostly positive and for those too busy to look up and read the entire review, I quote McGeary's concluding words:<br />
<em>"I like this book a lot and would recommend it to players in the 1700-2100 range. At club level the material will be a heavy winner and in local tournaments nearly as potent. The most valuable aspect for readers of the book is seeing how the opening flows together as the piece arrangements work with the selected pawn structures. A perfect book for improving players in the rating range I mentioned."</em><br />
<br />
<br />
These words certainly were true for the original edition and I hope I have contributed to the book's longevity.</div>Sverre Johnsenhttp://www.blogger.com/profile/00796086172553035906noreply@blogger.com2tag:blogger.com,1999:blog-4097677957983331811.post-54506275367945617742011-12-17T17:28:00.001+01:002011-12-17T20:10:22.135+01:00Quality King's Gambit Now for March<div dir="ltr" style="text-align: left;" trbidi="on">Another delay for Quality Chess' King's Gambit book.

<em><strong>A Ferocious Opening Repertoire</strong></em><br />
Author: Lakdawala<br />
Publisher: Everyman 2011<br />
Cyrus Lakdawala is a good writer. I find his style somewhat chatty but for many subjects that fits very well. Unfortunately he was probably not the right author for this subject. Not because it actually was his brother that used to play the Veresov but because Cyrus (possibly in contrast to his brother Jimmy) doesn't seem very interested in exact variations and tactical complications but prefers to discuss strategy and pawn structures. <br />

<em><strong>The Veresov: Surprise Your Opponents with the Tricky 2 Nc3!</strong></em><br />
Author: Davies<br />
Publisher: Everyman 2003<br />
I may have mentioned this elsewhere in this blog but I must admire Davies for the consistent high quality on his products (including his electronic ones). This too is a quite good book although not terribly ambitious. The author offers some sensible advice on how to select a Veresov repertoire but his analytical input seems relatively modest. <br />

<br />
First the <a href="http://www.qualitychess.co.uk/blog/?cat=7">publication date</a> of Quality Chess' book on the King's Gambit again was delayed. Now it's scheduled for December (<a href="http://www.qualitychess.co.uk/products/1/124/the_kings_gambit_by_john_shaw/">the book's info page</a> has not yet been updated). Obviously this may have been a tactical delay in order to prevent Taylor from referencing the QC book in his competing book.<br />
<br />
The response was quick and predictable. Now it's Taylor's book that is <span id="goog_2103610636"></span>delayed with eigth months <span id="goog_2103610637"></span>and <a href="http://www.everymanchess.com/chess/books/Attacking_Chess%3A_The_King%27s_Gambit">scheduled for August 2012</a>. Quality's counter move is not hard to suggest...<br />
<br />
However, somehow I don't think tactical considerations are the main reason for these delays. More likely the problems are analytical obstacles. The two principal challenges for anyone writing on the King's Gambit are:<br />
<ul style="text-align: left;"><li>Black has got unusually many playable defences. They are not all equally strong but they are Black's choices and he may have prepared them well.</li>
<li style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;">The established mainlines in the Kiezeritsky and Fischer defences may be fine for White in theory. However, they are quite difficult for White to handle and don't appear appealing to the typical aggressive KG player. </li>
</ul><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;">I will not at all be surprised if these books are delayed again. So now I am pondering the consequences for my own KG plans. The ideal situation would be to publish without any competing books at all, but that obviously isn't an option. The second best option seems to be to publish shortly after the main competitors, being able to build on their efforts. That would involve a lot of patience but as a matter of fact I have ideas for how to fill the wating time.</div></div>Sverre Johnsenhttp://www.blogger.com/profile/00796086172553035906noreply@blogger.com4tag:blogger.com,1999:blog-4097677957983331811.post-85857473266684902712011-10-08T21:20:00.003+01:002011-10-19T14:15:09.933+01:00The Muzio Family<div dir="ltr" style="text-align: left;" trbidi="on">Chess nomenclature is a difficult subject in general and in particular within the King's Gambit. For most practical players it is also a relatively uninteresting subject. So I will try to keep such discussions to a minimum in my coming King's Gambit book. However, I want what little I include to be as correct as possible. Therefore I will give the subject some coverage on this blog in the hope that knowledgeable readers may correct anything wrong or even debatable. <br />
<br />
In this entry I will try to identify and name White's positional piece sacrifices after the moves<strong> 1 e4 e5 2 f4 exf4 3 Nf3 g5.</strong><br />

The Polerio Attack, may be considered head of the Muzio Family. It is generally regarded as fairly respectable. However, it's quite possible that correct play leads to a forced repetition (which theoretically isn't a good result for White).<br />

The Lolli Attack is the black sheep of the Muzio family. White gives up his bishop instead of his knight and wins some time. Unfortunately White has insufficient compensation as Black after <strong>6...Ke8 7 Qxg4 Nf6</strong> starts winning his tempi back. The Lolli may be acceptable as a blitz or coffee house weapon but is probably unplayable above mediocre club level chess. <br />

This position, which may also arise from the move-order 4 d4 g4 5 Bc4, is known as the Ghulam Kassim Attack after the Indian player who published analysis on it around 1826 (at least the publication seems to have been available in 1843). It may transpose to a (probably good) variation of the Polerio Attack after a delayed 0-0 but White may also consider castling queenside.<br />

This position, which may also arise from the move-order 4 Nc3 g4 5 Bc4, is known as the MacDonnell Attack. It may transpose to the Polerio Attack after a delayed 0-0 but is more likely to merge with the Ghulam Kassim Attack after a quick d4 and queenside castling.<br />

This is the Rosentreter Attack which obviously is closely related to the Ghulam Kassim Attack, to which it may quickly transpose with an early d4. <br />
<br />
Instead 5 Bc4 would lead to the Ghulam Kassim Attack while 5 Nc3 would lead to the Sørensen Attack (below). <br />
<br />

This position I believe should be called the Sørensen Attack but I assume that some will argue that it should rather be the Quaade Attack. I am not at all sure what's correct and will try to look at bit deeper into the matter. My reasons for preferring Sørensen over Quaade are:<br />
<ol style="text-align: left;"><li><div style="text-align: left;">The mainline in the Quaade variation is 5 Ne5. It may even be argued that this knight move is the idea behind 4 Nc3 (as it is more or less unplayable in the Rosentreter variation, 4 d4).</div></li>
<li><div style="text-align: left;">In Bilguer's Handbuch, the line is attributed to Sørensen. </div></li>
</ol>Instead 5 Bc4 would have transposed to the MacDonnell Attack.<br />
<br />
This classification I think is the easy part of the Muzio nomenclature. The real challenge is to find good classification principles when the lines merge (as they tend to do). Maybe I will return to that subject in a future post.</div>Sverre Johnsenhttp://www.blogger.com/profile/00796086172553035906noreply@blogger.com0tag:blogger.com,1999:blog-4097677957983331811.post-46966900423404234472011-09-22T14:35:00.001+01:002011-09-22T14:38:22.401+01:00Cover Uncovered<div dir="ltr" style="text-align: left;" trbidi="on">Taylor's King's Gambit book now has a cover:<br />

I think the King's Gambit should wear something more classical. However, it probably draws a potential buyer's attention and that's quite an important feature.<br />
<br />
I have so far not paid much attention to cover design but I have been very pleased with the covers by <a href="http://www.firebrandx.com/">Wolff Morrow</a> that Gambit Publication has provided for my books. That attitude will quite soon have to change as the books I plan to publish will need covers. The classic and relatively easy solution is a picture of the subject position on a good-looking wooden chess set. Unfortunately that will not draw a lot of attention, so I will need to add a twist. I will keep my eyes open.</div>Sverre Johnsenhttp://www.blogger.com/profile/00796086172553035906noreply@blogger.com4tag:blogger.com,1999:blog-4097677957983331811.post-31904453759595030062011-09-10T08:33:00.002+01:002011-09-18T09:47:37.961+01:00On the Horizon<div dir="ltr" style="text-align: left;" trbidi="on">There are at least two new King's Gambit books on the horizon before my own book hopefully will be available some time in late spring 2012. <br />
<br />
First in the row is John Shaw for Quality Chess with simply <a href="http://www.qualitychess.co.uk/products/1/124/the_kings_gambit_by_john_shaw/">'The King's Gambit'</a>: <a href="http://www.qualitychess.co.uk/products/1/124/the_kings_gambit_by_john_shaw/"></a><br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjOFrXJ3BceWZXxzeASOzbVLc0J4JF1YAiVWfIVOTVOotJ0Qgt-rUdDL7P9K_q9ldHGlTY1zywV3q_aWMtOGtL-kZXt2LCXk9WDvdK7PN6yzvyp0iahPfXMilaO3DlyJl5jjxHzjB6dMnM/s1600/SS-image-2011-08-10-4e4257b8c085d.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" nba="true" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjOFrXJ3BceWZXxzeASOzbVLc0J4JF1YAiVWfIVOTVOotJ0Qgt-rUdDL7P9K_q9ldHGlTY1zywV3q_aWMtOGtL-kZXt2LCXk9WDvdK7PN6yzvyp0iahPfXMilaO3DlyJl5jjxHzjB6dMnM/s1600/SS-image-2011-08-10-4e4257b8c085d.jpg" /></a></div>The book is scheduled for October 2011. However, it has now been delayed so many times (and even <a href="http://www.amazon.com/Kings-Gambit-Jan-Pinski/dp/1906552711/ref=sr_1_1?ie=UTF8&qid=1315379442&sr=8-1">changed author</a>) that I take the announced publishing date with a grain of salt.<br />
<br />
I have more confidence in the content. Quality Chess have sometimes delivered products with surprising gaps in the material but their analysis has always been excellent.<br />
<br />
Next out is Timothy Taylor for Everyman Chess with <a href="http://www.everymanchess.com/chess/books/Attacking_Chess%3A_The_King%27s_Gambit">'Attacking Chess: The King's Gambit'</a>. Judging from the Everyman site it hasn't yet got a cover design. The book is scheduled for January 2012 (in EU) and as far as I know Taylor has generally kept his deadlines. His analysis tend to be lighter and somewhat less trustworthy QC's but often thought provoking. I look forward to seeing his effort.<br />
<br />
How will the existence of these two influence the sales potential for a third book? I must admit that I don't know. One point in my favour is the fact that I probably will be able to list these competing books in my bibliography. Reviews and publishing order will certainly influence the sales numbers. My gut feeling is that those who already love the King's Gambit will open their pockets and buy all new material but maybe the financial uncertainity even will influence this part of the economy?<br />
Another factor is the position and reputation of the chess publishing companies. How easy will it be to convince London Chess Center, Niggemann, New in Chess or Chess4Less to promote a book from a new publishing company. I am eager to find out!</div>Sverre Johnsenhttp://www.blogger.com/profile/00796086172553035906noreply@blogger.com7tag:blogger.com,1999:blog-4097677957983331811.post-15720111685432609842011-09-06T13:32:00.002+01:002011-09-18T09:48:17.796+01:00A Brief Return to Chess Blogging<div dir="ltr" style="text-align: left;" trbidi="on">My apologies for letting this blog sleep for so long with no explanation.

<div class="separator" style="clear: both; text-align: center;"></div>I am working on a manuscript on this fascinating opening now. I feel I have a lot of good content but I am struggling with the organization of the material. And of course there is always the danger that essential variations are refuted during analysis. <br />
<br />
For now I don't have any co-author but I hope that will change in the coming month.<br />

<div></div>Now Lakdawala recommends 3.c3 in order to reach the London safely, and that may also be the best attempt for those hoping for something related to the Torre. For Colle players, 3.e3 is the obvious choice. Unfortunately it's less clear that this will give White an edge than the Nimzo move-order 1.d4 Nf6 2.Nf3 e6 3.e3 - after all Black hasn't blocked his light-squared bishop.<br />
<br />
<div></div>However, none of these moves appears particularly threathening to Black's opening. It could be argued that Black is too optimistic trying to take on White's role in the early phase of the game. If that's the case, White now should play energetically in order to punish Black's arrogance. White's critical moves in the diagram position probably are:<br />
<ul></ul> A: 3.dxc5<br />
B: 3.c4<br />
C: 3.g3<br />
Let's look a little deeper:<br />
<br />
<b>A: </b><br />
<i>(1.d4 d5 2.Nf3 c5)</i><br />
<b>3.dxc5 </b><br />
White is playing a reversed Queen's Gambit Accepted. I will not go into much detail here, as this move was the repertoire choice in "<a href="http://www.gambitbooks.com/books/killer.html">A Killer Chess Opening Repertoire</a>". I will only point out one omission and one important alternative for White:<br />
<b>3...e6</b><br />
3...Nc6?! probably is dubious and wasn't mentioned in the Killer Repertoire. One interesting attempt at refutation is 4.a3 a5 5.Nc3 and now: <br />
a) 5...e6 6.Na4!? seems sufficient to keep the c-pawn.<br />
b) 5...Nf6 6.Bf4 e5 7.Nxe5 Bxc5 8.Nd3 also gave White a safe extra pawn in Bogdanovich-Hubel, Crailsheim 1998. <br />
c) 5...d4 probably is too optimistic: 6.Nb5 e5 7.e3 Bg4 8.Be2 (even stronger may be 8.exd4 exd4 9.Qe2+ Be7 10.Nd6+ Kf8 11.Bf4) 8...Bxf3 9.Bxf3 Bxc5 10.exd4 Bxd4 11.Nxd4 exd4 12.0–0 with an obvious advantage for White in Matlak-Orsag, Karvina 1992.<br />
<b>4.e4!? <o:p></o:p></b><br />
This is an important alternative to 4.c4 which was recommended in the Killer Repertoire.<br />
<b>4...Bxc5 <o:p></o:p></b><br />

With this move White offers Black to play the Tarrasch Defence. <br />
<div style="border: medium none;"><b>3... cxd4</b><br />
Instead the Tarrasch would arise after 3...e6. This old defence has, as far as I know, a sound theoretical standing, but many of the resulting positions are hard to defend against skilled opposition. More independent alternatives are:</div><div style="border: medium none;">a) 3...Nf6 4.cxd5 cxd4 5.Qxd4 Qxd5 6.Nc3 must be a shade better for White.

Should Black play the obvious developing move 5...Nc6, allowing White to have his desired Reversed Gruenfeldt?<b><br />
</b><br />
<b>5...Nc6 </b></div><div class="MsoNormal">This is Black's most popular move but there are alternatives:<br />
a) I don't know why 5...Nbd7!? is untested. Black threatens ...e5, so 6.Nxd4 e5 is natural.

c) 5...g6 is natural. Then 6.Nxd4 Bg7 7.c4 0–0 8.cxd5 Nxd5 9.Nb3 e6 10.Nc3 Nxc3 11.bxc3 Qc7 12.Rb1 with unclear play in Graf-Shomoev, Warsaw 2005 is one sample line.</div><div class="MsoNormal"></div><div class="MsoNormal"><b>6.Nxd4 e6 </b><br />
That's the problem when White tries to play a sharp line with colours reversed. You will usually find that Black opts for a non-critical line which nevertheless gives good chances of equality. White has scored massively after 6... e5 7.Nxc6 bxc6 8. c4, but partly that may be because the white players have very clearly outrated their opponents. One recent and typical example is 8...Be7 9.Nc3 Be6 10.Bg5 e4 11.Qa4 O-O 12.Rad1 Qb6 13.Bxf6 Bxf6 14.cxd5 cxd5 15.Nxd5 Bxd5 16.Rxd5 Qxb2 17.e3 with a very clear advantage to White in Burmakin-Lochte, Bad Wiessee 2008.<b><br />

It’s an interesting read and I will probably return to the subject. <br />
<br />
Our understanding of one opening is often influenced by our understanding (or lack of such) of other openings. I was curious when I saw Lakdawala briefly discard Black’s traditional mainline in the Barry attack (1.d4 d5 2.Bf4 Nf6 3.e3 g6 4.Nf3 Bg7 5.Be2 0–0 6.Nc3 c5 is the relevant London move-order) with the explanation that ‘7.dxc5 transposes to a favourable Reversed Catalan’ and some relatively brief variations. I must admit that the Catalan is not my field of expertise so I had to take a closer look at his variations - in particular as I had explored this line when researching ‘<a href="http://www.gambitbooks.com/books/killer.html">A Killer Chess Opening Repertoire</a>’ (and concluded that Summerscale’s 7.Ne5 probably still is White’s best try):<br />
<br />

<strong>7...Qa5</strong> <br />
<br />
This is the most popular reply and the only one mentioned in the book although 7...Nbd7!? has been played by Khalifman among others.<br />
<br />
<strong>8.Nd2!</strong> <br />
<br />
The exclamation mark is by Lakdawala and the move probably is White’s best try.<br />
<br />
<strong>8...Qxc5</strong> <br />
<br />
This is clearly most popular. Somewhat mysteriously Lakdawala gives the rare 8...Ne4!? as his main line. After 9.Ncxe4 dxe4 10.0–0 Nc6 11.c3 f5 12.Nb3 of Hodgson-Gullaksen, Stavanger 1989 he concludes that Black doesn’t have enough for his pawn. <br />
<br />
<strong>9.Nb3 Qb6 10.Nb5!</strong><br />
<br />
Again the exclamation mark is by Lakdawala. White has also tried 10.0-0, 10.a4 and 10.Nxd5?!.<br />
<br />
<strong>10...Ne8!</strong> (Dia)<br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgbrQt83O4kqeCQABelLbwUgfFYNyZGqIB1JtgOXzsxvEDMjW9bPSlLZHnalLeeMRyb86DNRvy7eddjCbd4BNkfn1JsZH-OGUnQInOxY3NFokqRX27ZYWxTr7UXBNUGNlsgDdT_rlyWmKI/s1600/BarryLakdawala2.gif" imageanchor="1" style="clear: left; cssfloat: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" bx="true" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgbrQt83O4kqeCQABelLbwUgfFYNyZGqIB1JtgOXzsxvEDMjW9bPSlLZHnalLeeMRyb86DNRvy7eddjCbd4BNkfn1JsZH-OGUnQInOxY3NFokqRX27ZYWxTr7UXBNUGNlsgDdT_rlyWmKI/s320/BarryLakdawala2.gif" /></a></div>This is not mentioned in the book but has been played by Hebden and Lars Bo Hansen among others and is given an exclamation mark by Ftachnik in Megabase. Lakdawala only mentions 10...Na6 11.Be5! and White probably is better as ‘Bd4 is in the air’. The move is far from obvious but as there clearly are some threaths to c7 it's not particularly surprising either.<br />
<br />
<strong>11.Qxd5 </strong><br />
<br />
What else? Black was threatening ...e5 as well as ...Bxb2.<br />
<br />
<strong>11...Bxb2 12.Rb1 Bg7 13.0–0 Nc6 14.c4</strong> (Dia)<br />
<br />
Not 14.N5d4? e5! 15.Nxc6 bxc6 and Black wins.<br />
<br />
So far everything seems very natural if not entirely forced. Now it seems Black has at least two ways to equalize (as a matter of fact Rybka also thinks 14...a6!? and 14...e5 look OK):<br />
<strong>A: </strong><strong>14...Bf5 15.Rbd1 Nf6</strong> <br />
<br />
Or 15...Nb4 16.Qd2 Na6 17.Nc3 Nf6 18.Qc1 Rac8 19.Be5 Be6 20.Bd4 Qb4 = L.B.Hansen-Djurhuus, Reykjavik 1995.<br />
<br />
<strong>16.Qc5 e5 17.Bg3 Ne4</strong> <strong>18.Qxb6</strong> <br />
<br />
Rybka claims that 18.Qa3 is equal. That may well be right; the position looks somewhat strange and I find it hard to evaluate.<br />
<br />
<strong>18...axb6 19.Ra1 Rfd8</strong> and in Akselrod-Salinnikov, Tomsk 2003 Black was clearly better thanks to his activity.<br />
<br />
<strong>B: </strong><strong>14...Nf6 15.Qc5 e5! 16.Bg3 Ne4</strong> (Dia)<br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh7leUNZVeVxNTbWt8MQhyDxim2Ia2zOju35bSLO-a2zMP6j1ys0HMiqZYXOpzf4k4H_KP4D6tItIcvWc6Y_sveWCRrpVI7sLf1Rgd39A2QRp9T-Jd6o5h-XphkccRkJI2n5WTo6F-jPLU/s1600/BarryLakdawala3.gif" imageanchor="1" style="clear: left; cssfloat: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" bx="true" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh7leUNZVeVxNTbWt8MQhyDxim2Ia2zOju35bSLO-a2zMP6j1ys0HMiqZYXOpzf4k4H_KP4D6tItIcvWc6Y_sveWCRrpVI7sLf1Rgd39A2QRp9T-Jd6o5h-XphkccRkJI2n5WTo6F-jPLU/s320/BarryLakdawala3.gif" /></a></div>This too looks fine for Black who is active and has the bishop pair.<br />

<br />
b) 17.Qa3 and now 17...Nxg3 18.hxg3 Rb8 (18...Rd8?! 19.c5 +/- Klimets-Gerasimovitch, St Petersburg 2002) 19.c5 Qd8 20.Rfd1 probably is a little better for White. However, Rybka thinks that 17...Bf5 as well as 17...Be6 is at least OK for Black.<br />
<br />
<br />

<strong>Conclusion:</strong> <br />
I have not found a path to advantage for White after 7.dxc5. That doesn't mean there isn't one, but Lakdawala's explanation clearly isn't sufficient for me. Maybe someone who knows more about the Catalan (and consequently more about the Reversed Catalan too) can point me in the right direction?Sverre Johnsenhttp://www.blogger.com/profile/00796086172553035906noreply@blogger.com7tag:blogger.com,1999:blog-4097677957983331811.post-78941863904145332772010-07-29T08:36:00.010+01:002010-11-24T10:50:32.669+01:00The Queen's Pawn Family 1 - OverviewI have somewhere promised an overview and comparison of the so-called Queen's Pawn Openings (also known as D-pawn Specials or even D-pawn Deviations).

<br />
<br />
<em>1...d5 is an older move than 1...Nf6, so this is the classical starting position for the Queen's Pawn Openings. By deviating at this early point White makes sure that the game will be played on his homeground.</em> <br />
<br />
<br />
<br />
<br />
<br />
<br />
a) 2.g3?! - A poor relative of the Catalan. Black can equalize by an early ...c6 and ...Bf5.<br />
b) 2.e3 - Introduces the <strong><em>Stonewall Attack</em></strong> (Bd3+f4+c3). A critical line is 2...Nf6 3.Bd3 Nc6.<br />
c) 2.Bf4!? - The <strong><em>Neo-London</em></strong>. By some experts considered to revitalize the classical London system.<br />
d) 2.Bg5!? - The <strong><em>Hodgson Opening</em></strong>. Frequently used as a companion system to the Trompowsky.<br />
e) 2.e4?! - The <strong><em>Blackmar Diemer Gambit</em></strong> (BDG). Not entirely correct but many prefers to decline the pawn offer with 2...e6 (French) or 2...c6 (Caro Kann).<br />
f) 2.Nc3!? - Normally leads to the <strong><em>Veresov Opening</em></strong> after 2...Nf6 3.Bg5 but 2...Bf5 may be best.<br />
g) 2.a3!? - <strong><em>The Prie Opening</em></strong>. White argues that 2...c5 is too risky and all D-Pawn Specials are inferior (the more so a move down). <br />
h) 2.c3?! - A sly but slow move which may lead to the Colle, the London or the Torre. 2...Nf6 followed by 3...Bf5 should equalize.<br />
i) 2.Nd2 - Normally leads to some kind of <strong><em>Colle</em></strong> after 2...Nf6 3.e3.<br />
j) 2.b3 - May lead to a Colle Zukertort but I cannot see how White can benefit from delaying e3 and Nf3.<br />
k) 2.h3?! - A joke move favoured by some London players who will follow up with Bf4 and reach an only slightly inferior London.<br />
l) 2.f4?! - A too primitive attempt to play the <strong><em>Stonewall Attack</em></strong>. 2...Nf6 followed by 3...Bf5 at least equalizes.<br />

<br />
<em>2.Nf3 is a sound and flexible move and the starting point of most Queen's Pawn openings. Black has a few interesting alternatives to 2...Nf6, such as 2...c5 and 2...Bf5!? but most alternatives, including 2...c6 and 2...e6 allow White to go ahead with his planned set-up.</em> <br />
<br />
<br />
<br />
<br />
<br />
<br />
a) 3.g3?! - An inferior version of the Catalan 3...Bf5 or 3...c6 followed by 4...Bf5 equalizes.<br />
b) 3.Bg5?! - An inferior version of the Torre. 3...Ne4 equalizes.<br />
c) 3.Bf4 - The classical <strong><em>London System</em></strong>. 3...c5 4.e3 Nc6 5.c3 Qb6 6.Qb3 c4 7.Qc2 Bf5 is probably equal.<br />
d) 3.Nbd2 - A rare path to the Colle. 3...Bf5 probably equalizes.<br />
e) 3.c3!? - Lakdawala's path to the London. The idea is to meet 3...c5 with 4.dxc5 and most other moves with 4.Bf4.<br />
f) 3.Ne5 - A possibly underestimated attempt to reach a <strong><em>Stonewall Attack</em></strong> (with f4. White hopes to fight for an advantage after 3...Bf5 4.c4.<br />
g) 3.a3 - A version of the <em><strong>Prie System</strong></em>. <br />
h) 3.b3?! - Usually an attempt to reach the <strong><em>Colle Zukertort</em></strong> system. 3...Bf5 equalizes comfortably.<br />
i) 3.Nc3 - Looks similar to the Barry Attack but is rather pointless as long as Black hasn't played ...g6.<br />
j) 3.h3?! - Normally another way to reach a slightly inferior London system after a delayed Bf4.<br />

<em>After 3.e3 we are in Colle territory, and might reasonably stop at that, noting that 4.c4 would still be a (harmless) Queen's Gambit. However, the Colle comes in different flavours too:</em><br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
a) 4.dxc5 - This is an attempt to play the Queen's Gambit accepted a tempo up but 4...e6 probably gives theoretical equality.<br />
b) 4.b3 - This is not White's most promising variation of the<em><strong> Colle Zukertort</strong></em>. After 4...Nc6 5.Bb2 Bg4 Black is equal. Also Kaufman's 4...cxd4, taking advantage of the fact that Bc1 not can use two diagonals, makes sense.<br />
c) 4.c3 - Heads for the (Classical) <strong><em>Koltanowski Colle</em></strong>. The interesting question is whether Black now should play the modest 4...e6 or the more ambitious 4...Nc6. <br />
d) 4.Nbd2 - A seemingly sensible <strong><em>Colle</em></strong> move that isn't even mentioned in several works on the Colle.<br />
e) 4.Bd3!? - A slightly provocative attempt to stop ...Bf5 and keep open both the b3 and c3 options. The critical reply of course is 4...c4!?<br />
f) 4.a3!? - An attempt to reverse colours - perhaps planning dxc5 followed by b4 and c4. But is a3 really useful after 4...cxd4 5.exd4? <br />
g) 4.Ne5 - White intends to follow up with f4, Bd3 and c3, reaching a <strong>Stonewall Attack</strong>.<br />

<br />
<em>This is the traditional starting position of the Colle. It should be noted that this position is at least as likely to appear from the move-order 1.d4 Nf6 2.Nf3 e6 3.e3 d5. White can still return to lines of the Queen's Gambit with 4.c4 but within the Colle there are these options:</em><br />
<br />
<br />
<br />
<br />
<br />
<br />
a) 4.Be2 - A reversed Queen's Gambit Declined. Solid for Black but unambitious for White.<br />
b) 4.b3 - Reveals White's plan to play a <strong><em>Colle Zukertort</em></strong> earlier than necessary.<br />
c) 4.c3 - Reveals White's plan to play a <em><strong>Colle Koltanowski</strong></em> earlier than necessary.<br />
d) 4.a3 - Attempts to play a Queen's Gambit Accepted a tempo or two up after 4...c5 5.dxc5 Bxc5 6.b4 but that's hardly sufficient for an advantage.<br />
e) 4.Ne5 - White intends to follow up with f4, Bd3 and c3, reaching a <em><strong>Stonewall Attack</strong></em>. Probably more promising with Black's light-squared bishop locked in than the 3...c5 version.<br />
f) 4.Nbd2!? - A seemingly sensible <strong><em>Colle </em></strong>move that isn't even mentioned in several works on the Colle.<br />
g) After the main move 4.Bd3 and the extremely natural 4...c5 White has these options: <br />
g1) 5.c4 - Still a Queen's Gambit (a rather harmless Tarrasch)<br />
g2) 5.0–0 - A provocative attempt to keep options open. 5...c4 6.Be2 b5 is the critical line.<br />
g3) 5.b3! - The <strong><em>Colle Zukertort</em></strong>, a legitimate try for an advantage even at GM level. <br />
g4) 5.c3 - The <strong><em>Colle Koltanowski</em></strong>, actually a reversed Slav and quite dangerous for the unprepared.<br />

<br />
<em>With his first move Black displays a less compromising attitude than 1...d5 does. This can be seen as a reason for White to avoid a theoretical confrontation. However, it must also be said that it is probably harder for White to fight for a real advantage without an early c4 if Black knows what he is doing. </em><br />
<br />
<br />
<br />
<br />
<br />
<br />
a) 2.g3 - An inferior attempt to reach the Catalan. Black is equal after 2...d5 followed by ...c6 and ...Bf5.<br />
b) 2.Bg5 - The <strong><em>Trompowsky</em></strong>. Now almost mainstream and occasinally tested at the highest level. White will frequently capture the f6 knight if that doubles Black's pawns but also setting up a Stonewall with pawns on c3, d4, e3 and f4 makes sense.<br />
c) 2.c3 - Extremely flexible and extremely tame. One idea is to meet 2...g6 as well as 2...e6 with 3.Bg5 (which both may be categorized as Trompowskys).<br />
d) 2.Bf4 - A somewhat experimental branch of the <strong><em>Neo London</em></strong>. 2...c5 and 2...d6 must be the critical lines.<br />
e) 2.Nc3 - After 2...d5, 3.Bg5 is the <strong><em>Veresov Attack</em></strong>. Not very popular for the moment but that may be about to change.<br />
f) 2.Nd2 - Used to be a favorite of Varga's. White to some extent threatens 3.e4 and after 2...d5 3.Nf3 we have a <strong><em>Colle </em></strong>(IBd).<br />
g) 2.e3 - A possibly inferior version of the <strong><em>Stonewall Attack</em></strong>. 2...g6 is supposed to be strong but White can pretend he is playing a reversed French vs. King's Indian Attack.<br />
h) 2.f4 - An ugly attempt to play the Stonewall Attack. 2...d5 followed by 3...Bf5 possibly is the simplest solution but also a plan including ...d6 and ...e5 looks tempting. <br />
i) 2.g4 - The <strong><em>Gibbins-Weidenhagen Gambit</em></strong>. Almost certainly unsound but White has some practical chances after 2...Nxg4 3.e4.<br />
j) 2.a3 - This attempt to reach a reversed QP opening doesn't make much sense after 2...g6.<br />
k) 2.b3 - May lead to a Colle Zukertort but I cannot see how White can benefit from delaying e3 and Nf3.<br />
l) 2.f3 - May lead to a <em><strong>Blackmar Diemer Gambit</strong></em> after 2...d5 3.e4 dxe4 4.Nc3. Probably 3...e6 is a simpler cure. 2...g6 3.e4 d6 is a Pirc.<br />
m) 2.h3 - Looks rather pointless but if White follows up with Bf4 and Nf3 he will probably reach a playable London position.<br />

<em>Nimzo- and Queen's Indian players may have a tougher task against the D-pawn Specials, (in particular the Colle) than others. Against this move-order the Colle Zukertort probably holds prospects for a small advantage.</em><br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
a) 3.e3 - White heads for some branch of the <strong><em>Colle</em></strong> but may need other ideas against 3...b6 and 3...c5.<br />
b) 3.Bg5 - The <strong><em>Torre System</em></strong><br />
c) 3.Bf4 - An important branch of the<em><strong> London System</strong></em><br />
d) 3.c3 - A tricky move, keeping open options to enter the Koltanowski Colle, the London or the Torre.<br />
e) 3.Nbd2 - Possibly an underestimated branch of the <strong><em>Colle</em></strong>. Black must decide whether he considers e4 a threat or not. <br />
f) 3.a3 - Another branch of the <strong><em>Prie System</em></strong>. White takes on Black's role with a marginally useful extra tempo.<br />
g) 3.b3 - Heads for a Colle Zukertort but White gains nothing by revealing his plan too early.<br />
h) 3.h3 - Another joke path to a playable if uninspiring London set-up.<br />
i) 3.Nc3 - Looks similar to the Barry Attack but is rather pointless as long as Black hasn't played ...g6.<br />

<br />
<em>The King's Indian is one of the toughest tests for any Queen's Pawn System. Black develops quickly and has various ways to challenge the centre. Lines with ...d6 followed by ...e5 or ...c5 probably are the most challenging but quieter lines with ...d5 are also available.</em> <br />
<br />
<br />
<br />
<br />
<br />
<br />
a) 3.e3?! - The <strong><em>Colle</em></strong> hasn't got a great reputation against the King's Indian, as Black can force ...e5 with relative ease. However, 3...Bg7 4.b4!? may well be OK for White.<br />
b) 3.Bg5 - Purists will say that this isn't strictly speaking the <strong><em>Torre Attack</em></strong>. The Torre versus King's Indian (which it's sometimes called) probably is slightly less promising than the 2...e6 version. <br />
c) 3.Bf4 - The third major branch of the <strong><em>London System</em></strong>. <br />
d) 3.c3!? - Delays the decision of where (if?) to develop the dark-squared bishop but there is little to be gained as White will soon have to commit himself anyway after 3...Bg7 or 4...0-0.<br />
e) 3.Nc3!? - introduces the <em><strong>Barry Attack</strong></em> after 3...d5 4.Bf4 (or a version of the 150-Attack after 3...Bg7 4.e4).<br />
f) 3.Nbd2 - Heads for a <em><strong>Colle</strong></em> after 3...d5 4.e3 or a quiet Modern after 3...Bg7 4.e4.<br />
g) 3.h3 - Once thought to be the most accurate move-order for White to play the London System against the King's Indian. However, the move is too slow to stop the ...Nfd7 and ...e5 plan.<br />
h) 3.b3 - Has been played by Smyslov and Portisch but is mainly a modest way of getting the pieces out.<br />
i) 3.b4!? - The <strong><em>Arkell System</em></strong> - at least if White keeps his c-pawn back and plays Nd2-c4, trying to restrain ...e5. I believe there is also a name for the more traditional approach with an early c4 but that line must belong to the King's Indian complex.<br />
<br />
That's all folks! (well, I am sure I have forgotten something, so I expect to edit and update the overview)<br />
<br />
The plan now is to take a closer look at some of the systems (mainly the Colle London and Torre), comparing them and perhaps suggest how some systems can be combined. I have also started collecting bibliographies.<br />

<br />
The new title is "<a href="http://www.olibris.fr/FicheProduit.aspx?Id=54">Répertoire d'ouvertures efficace</a>" which I assume must mean "An Efficient Opening Repertoire". The subtitle "pour joueur d'échecs paresseux" I think must mean "for lazy chessplayers". A little less bloodthirsty than the original English title.<br />
<br />
As you can see, also the cover is a little less aggressive. I prefer <a href="http://www.firebrandx.com/c089.htm">Wolff Morrow's artwork</a>, but the French one is quite nice too, in a very different way. Can anyone tell me the name of the artist (I assume his signature can be seen below the drawing, but I am unable to read it)?<br />
<br />
I am proud to now have been translated to two major European languages, and hope <a href="http://www.gambitbooks.com/index.html">Gambit Publishing</a> or the French publisher <a href="http://www.olibris.fr/">Olibris</a> will be kind enough to send me a few copies.<br />
<br />
<strong>Update July 21st</strong><br />
I found <a href="http://www.chess-and-strategy.com/2010/07/echecs-livres-repertoires-douvertures.html">this advertisment</a> which includes a review. My French is quite poor but I will try to translate the conclusion:<br />
<br />
<span style="color: #e69138;">Autre atout de l'ouvrage, le choix des parties illustratives, jouées par des joueurs qui ne sont pas des grands-maîtres. Une autre bonne idée car c'est bien ce qui se passe pour la majorité des tournois d'échecs pour nous autres amateurs. Avouons-le tout bonnement, c'est une idée géniale !</span><br />
<br />
<br />
<span style="color: #3d85c6;">Another asset of the work is the choice of illustrative games, played by players who are not Grandmasters. This is a good idea because for us amateurs this is what occurs in the majority of chess tournaments. Let us acknowledge that this simply is a brilliant idea!</span><br />
<br />
Well, I hope that isn't too inaccurate. Please inform me if you can improve the translation. Anyway, "<a href="http://www.chess-and-strategy.com/">Chess & Strategy</a>" appears to also be a chess vendor, so the 'review' cannot be expected to be very critical and I will not read too much into it.Sverre Johnsenhttp://www.blogger.com/profile/00796086172553035906noreply@blogger.com5tag:blogger.com,1999:blog-4097677957983331811.post-46531661960993156182010-07-10T09:21:00.001+01:002010-07-10T09:22:07.993+01:00Chessville Reviews Win with the Stonewall Dutch<div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgB5QcdGHa2ur_MRMp2MTmoKHYW-P0nAMfQn4T8E17dKtnFAkCxE3wm3C_xGeuL1u0-wB5rMm03Ps5vNgRW5VVr0_dvyNZaDrEK-tPIK-qTLnP1GI7d1hE-t_Rx4AdYZgiQgQj8_HsN9JA/s1600/CVlogo.jpg" imageanchor="1" style="clear: left; cssfloat: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" rw="true" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgB5QcdGHa2ur_MRMp2MTmoKHYW-P0nAMfQn4T8E17dKtnFAkCxE3wm3C_xGeuL1u0-wB5rMm03Ps5vNgRW5VVr0_dvyNZaDrEK-tPIK-qTLnP1GI7d1hE-t_Rx4AdYZgiQgQj8_HsN9JA/s320/CVlogo.jpg" /></a></div>After a few long periods of dormancy, <a href="http://www.chessville.com/index.html">Chessville</a> now seems to be fully activated again. Today I noted a <a href="http://www.chessville.com/reviews/WinwiththeStonewallDutch.htm">review of 'Win with the Stonewall Dutch'</a> by Bill McGeary.<br />
<br />
As the reader can easily confirm, McGeary is fairly detailed and in general quite positive. I will just quote his conclusion:<br />
<em>I am sure that new ideas and valuations in lines have likely already come to light since the publication of this book, but it remains an excellent work for a player looking to bring the Stonewall into their armory. Because of the strength of the writers, and the complexity of material, this book might be a bit bewildering for players below the 2000 level, and even some above, yet it could well act as one of the steps along the road upward.</em><br />

Just briefly noting that there are now <a href="http://www.everymanchess.com/extract/Play%20the%20London%20System.zip">pdf-extracts</a> from Lakdawala's <a href="http://www.everymanchess.com/chess/books/Play_the_London_System">'Play the London System'</a> at <a href="http://www.everymanchess.com/">Everyman's chess book site</a>. <br />

I note with some surprise that the book now has reached 256 pages, which is 64 more than the last time I checked. It is still hard to judge how much analytical content there is and how well organized it is. However, the book still seems promising and I am pleased to note that the introduction contains a good portion humour.Sverre Johnsenhttp://www.blogger.com/profile/00796086172553035906noreply@blogger.com2tag:blogger.com,1999:blog-4097677957983331811.post-80562359877744456632010-06-03T07:25:00.010+01:002010-06-21T10:04:00.979+01:00Chess Cafe Reviews the Killer Repertoire<div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjRPsEeo7UYqR5T-z2QD7FrXiMllycjtT1M0B80rE0NBdNQGr74QGfqMEJvRZzWJd4i3g3xH0nUACn2tuNNY7VyZJtm28fpyACY3d8_ETjY8oj8sTPDkcIYd6bE2wO5MREV0ZAkZLvia0E/s1600/killer.jpg" imageanchor="1" style="clear: left; cssfloat: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" gu="true" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjRPsEeo7UYqR5T-z2QD7FrXiMllycjtT1M0B80rE0NBdNQGr74QGfqMEJvRZzWJd4i3g3xH0nUACn2tuNNY7VyZJtm28fpyACY3d8_ETjY8oj8sTPDkcIYd6bE2wO5MREV0ZAkZLvia0E/s320/killer.jpg" /></a>In his influential monthly <a href="http://www.chesscafe.com/hansen/hansen.htm">chess book column - Checkpoint</a>, Carsten Hansen yesterday reviewed (among others) "<a href="http://www.gambitbooks.com/books/killer.html">A Killer Chess Opening Repertoire</a>" under the heading <strong><em>'Happy Days for Queen's Pawn Enthusiasts'</em></strong>. Generally his review is favourable and his conclusion is: </div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><em>'However, the meat of the book is on the Colle and Colle-related set-ups, and in those chapters the book really proves its worth. Overall, it is an easily approachable book; the repertoire is by and large not too difficult to follow, even if some of the surprise value has been eliminated by the original book being on the market for more than ten years. In many ways, this present work is a considerable upgrade over the original, and, even by today's high standards for opening books, it is a very good book. It can be enjoyed by players rated up to around 2000.'</em></div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><br />
</div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;">He awards the book with three stars (out of a maximum of four). I obviously would have liked one more star but cannot really complain. According to the Rating Chart three stars is 'good' and four stars 'excellent'. So when Hansen says it is 'very good' I will assume the extra star was within shooting range.<br />
<br />
I don't really agree that the chapters on the Colle (Zukertort) are the core of the book. As I see it, the book's starting point is the Barry Attack (1.d4 Nf6 2.Nf3 g6 3.Nc3 d5 4.Bf4). With this as a basis it adds other low-theory systems - including some Colle related systems - in order to supply the reader with a complete 1.d4 repertoire. However, this is mainly a question of perspectives and in support of Hansen's view it must be admitted that Colle-related systems take up at least 68 of the book's 192 pages.</div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><br />
</div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;">I note with interest that Hansen recommends the book for players up to 2000. In his 'Introduction to the First Edition' from 1998, Summerscale writes: <em>'This book is aimed primarily at club-level players with a playing strength of up to about 2200 Elo (or 200 BCF)'</em>. I briefly considered commenting upon this when writing my 'Updater's Notes' as I had a feeling that today's 2200 players generally prepare a bit deeper than they did a decade ago. When I after all decided not to comment on Summerscale's original estimate, it was because I felt that in general the added material compensated for theory's development.</div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><br />
</div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;">What I really don't understand is this remark:</div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><em>'There are even some bizarre recommendations towards the end of the book, such as how White is to meet 1 d4 d6, where the book recommends 2 e4, which allows Black to take the game to a Pirc or Modern Defense or even the Philidor after 2..Nf6 3 Nc3 e5 4 Nf3. I can't see too many club players, who employ the Colle as white, also going for 2 e4, which changes the entire nature of the game.'</em></div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><br />
</div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEike2Ag3JPaDsUv_d_0FTRB20Dgi9QQLQ5RrCQcpYUAfMBBVVEcKdBxAflLKznpORN-SHoG3JG_Act8W89yEPvZMqFp1GD6DZ9ZNHn5et1Gparrbh5zugKHMN0qBJuYzkeymqbZHhBLLA0/s1600/Pirc.gif" imageanchor="1" style="clear: left; cssfloat: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" gu="true" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEike2Ag3JPaDsUv_d_0FTRB20Dgi9QQLQ5RrCQcpYUAfMBBVVEcKdBxAflLKznpORN-SHoG3JG_Act8W89yEPvZMqFp1GD6DZ9ZNHn5et1Gparrbh5zugKHMN0qBJuYzkeymqbZHhBLLA0/s320/Pirc.gif" /></a>This is a bit mysterious as 2.e4 clearly isn't a bizarre move in itself. It leads to a positions of a different nature than the Colle but so do many other of the books proposed lines. Hansen's point must be that allowing a transposition to the Pirc, Modern and Philidor doesn't fit well with the rest of the book's proposed repertoire. This criticism would make sense if there wasn't a full chapter in the book on the 150-Attack against the Pirc and Modern. </div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><br />
</div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;">Summerscale's original work didn't mention 1...d6, and I must admit that I too originally missed this gap in the repertoire. So when Gambit's editorial staff pointed this out and suggested 2.d4 and a condensed repertoire to cover the non-Pirc lines, I was happy to accept their suggestion. The only sensible alternative seemed to be 2.Nf3, when 2...Bg4!? would require some analysis as well as some prose discussing the strategic points of Black's ...Bxf3 option. In addition there also was 2...f5!? which didn't quite fit into the proposed repertoire against the Dutch.</div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"> </div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;">So in my opinion the only bizarre aspect of 1.d4 d6 2.e4 is the book's attempt to offer a repertoire against the Czech and the New Philidor in half a column. This clearly isn't sufficient to be well prepared in the professional sense of the word. But for the sub-2200 readers it doesn't seem too bad. 1...d6 is after all only Black's 6th most popular move and will normally lead to the Pirc. The Czech (3...c6) seems to be out of fashion (I think there are theoretical problems in the 4.f4 lines) and not that hard to face unprepared anyway. That leaves the Philidor which is an interesting opening where Black has good prospects to outplay a weaker player in the middlegame. However, it's mainly Black that has to be careful in order to survive the first 15 moves.</div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><br />
</div>When re-reading the text on Black's non-Pirc options I notice one unfortunate omission. After 1.d4 d6 2.e4 Nf6 3.Nc3 e5 4.Nf3, Black may try the Antoshin variation 4...exd4 5.Nxd4 Be7, which isn't mentioned at all. However, this too is a very quiet option where White scores well above average, so if a reader should happen to meet it and lose the game, I would expect him to blame his own middlegame play rather than the book.Sverre Johnsenhttp://www.blogger.com/profile/00796086172553035906noreply@blogger.com7tag:blogger.com,1999:blog-4097677957983331811.post-28545877790027125432010-05-30T20:36:00.001+01:002010-05-30T20:44:50.273+01:00Relay ChessThere are countless chess variants; obscure and popular; weird and playable. In an earlier entry I listed <a href="http://sverreschesscorner.blogspot.com/2007/11/top-10-chess-variants.html">some of my favourites</a>. However, I now realize that I forgot an important category of games - those variants that (mostly) retain the standard rules but add an element of physical skill. Chess Boxing seems to be the new big thing and I have already had an entry <a href="http://sverreschesscorner.blogspot.com/2009/09/future-of-kung-fu-chess.html">on Kung Fu Chess</a>. I suppose Drinking Chess (Shots Chess) is still the best known, and may return to this activity as well as the related Valhalla tournaments in a later entry. However, for now I will concentrate on variants better suited for younger players.<br />
<br />
If you ever need an outdoor activity for young chess players, then Relay Chess may be the solution. The main rules are:<br />
<br />
<ol><li>Relay chess is a competition between two teams. On each team there should be somewhere between three and seven players. The teams don’t necessarily have to have the same number of players but the players should keep their place in their team's queue.</li>
<li>The teams are placed some distance away from a chess board. The distance should be sufficient to make it difficult for the players to see what’s going on. Preferably there should be an arbiter near the board.</li>
<li>Use a chess clock with a reasonable amount of time (e.g., 10 minutes for each team), so that the players will have to run and move quickly in order not to lose on time.</li>
<li>The player first in the white row runs to the board, makes his first move and presses the clock. As soon as the white player has pressed the clock, the first player on Black’s team may start running.</li>
<li>A player who has completed his move should immediately return and take his place (at the back of the queue). The next player on his team may not start his run before the previous player has returned (and the player on the other team has completed his move and pressed the clock).</li>
</ol><br />
<div>In addition it may be a good idea to agree on this (but remember that this should be fun and don’t spend too much time on the finer points of the rules - a rematch is usual the perfect way to resolve a discussion):</div><br />
<ul><li>Should the players be allowed to inform their team about their latest move and the position on the board or give advice? Shout advice to the player at the board? </li>
<li>What happens if a player makes an illegal move? Stumbles over the board? Loses a piece on the ground?</li>
</ul><br />
<div>I hope to add some pictures to this entry in a few days as there is an informal Norway-England competition coming up. </div><br />

If you read some German, you could do worse than following this apparently frequently updated chess blog.<br />
<br />
For those not reading German, here is an attempt to translate the summary:<br />
<br />
<span style="color: lime;">"Die meisten der vorgestellten Systeme können ohne großen Aufwand erlernt werden und erfordern nur geringe Variantenkenntnisse. Selbstredend dürfte dadurch sein, dass der Spieler demzufolge keine großen Stellungsvorteile erhoffen darf , aber die Solidität sichert ihm zumeist ausgeglichenes Spiel. Ein Repertoire für Praktiker auf Vereinsniveau. Wer im Besitz der Erstausgabe ist und die Systeme im Repertoire hat, wird voraussichtlich mehr von spezialisierter Literatur profitieren, anstatt das Update zu erwerben."</span><br />
<br />
<span style="color: red;">"Most of the systems presented can be adopted quite easily and demand only modest knowledge of exact variations. This may be due to the systems offering no sizable opening advantage but their solidity will at least ensure you equal play. A repertoire for practical players at club level. Presumably, if you already have the first edition and have adopted the repertoire you will profit more from specialist literature than from getting this update."</span><br />
<br />
(My German is to a large extent based on the language's similarity with Norwegian and contains an element of guesswork. So any improvements/corrections will be appreciated.)<br />
<br />
I don't quite agree with this conclusion and may add some comments at a later point.Sverre Johnsenhttp://www.blogger.com/profile/00796086172553035906noreply@blogger.com0tag:blogger.com,1999:blog-4097677957983331811.post-84551620022676835242010-05-06T10:43:00.001+01:002010-05-06T10:48:35.773+01:00Killer Repertoire in Marsh TowersIn his <a href="http://marshtowers.blogspot.com/2010/05/chess-reviews-139.html">chess reviews today</a>, Sean March among other reviews "<a href="http://www.gambitbooks.com/books/killer.html">A Killer Chess Opening Repertoire".</a> The potential buyer can also find a snapshop from one of the new games I added and his impressions regarding the extent of the update. I don't think his estimate of 5 new game references on a double spread is far off but I know that the changes are far from uniformly distributed.<br />
<br />
Marsh has certain doubts about some of the repertoire choices but seems quite satisfied with the update and concludes: <br />
<em>"This is a neat little book which can provide serious ammunition for keen club players."</em>Sverre Johnsenhttp://www.blogger.com/profile/00796086172553035906noreply@blogger.com5tag:blogger.com,1999:blog-4097677957983331811.post-11664591998348595492010-04-29T11:07:00.001+01:002010-04-29T12:09:01.797+01:00Elburg reviews "A Killer Chess Opening Repertoire"Only this Monday afternoon I got hold of some copies of the revised "A Killer Chess Opening Repertoire". Since then I have been very busy and haven't really had the time to examine the book closely. My first impression is that most (possibly all) of my late corrections/additions made it to the final varsion. <br />
<br />
Today I found the first review of the book at <a href="http://chessbooks.nl/elburg146.html">John Elburg's chess reviews</a>. As expected he is quite positive. My guess is that Gambit on their <a href="http://www.gambitbooks.com/books/killer.html">info page</a> will only quote his concluding line:<br />
<strong>Conclusion:</strong> <strong>Impressive update!</strong><br />
<br />
Elburg points out that there is no bibliography and thinks this would have been useful for the reader. Well, he may be right. However, as a matter of fact I originally wrote a quite extensive bibliography but eventually decided to skip it as it would either have been somewhat misleading or would have needed a lot of comments. For instance it would have been somewhat misleading to list the large number of books that I consulted only to find out that they had nothing new to offer.<br />
<br />
Elburg also mentions my analysis on Trygstad’s 1.d4 f5 2.Bg5 h6 3.Bh4 g5 4.e4 Rh7!? which may be the part where I did the most analytical work (or more precisely: where I had Rybka slaving for the longest time). <br />
<br />
<div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi_obnRgzDmRcqy-QPDFf0Q2fysBgqq6dKOj3yZSUienkZwj8ugO3pzFC-GooZZTBl4UJztsAliOpgdd5g64ernbHnSao-b_d_GooQ0B-YdT8jZfie-1onF4aKYaI9DehC1w6eJqNx_jX0/s1600/Trygstad.gif" imageanchor="1" style="clear: left; cssfloat: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi_obnRgzDmRcqy-QPDFf0Q2fysBgqq6dKOj3yZSUienkZwj8ugO3pzFC-GooZZTBl4UJztsAliOpgdd5g64ernbHnSao-b_d_GooQ0B-YdT8jZfie-1onF4aKYaI9DehC1w6eJqNx_jX0/s320/Trygstad.gif" tt="true" /></a></div><br />
As a matter of fact only a tiny fraction of my analysis was actually included in the book. Initially I spent a lot of time trying to find a way to a clear advantages in the semi endgames resulting from Williams' mainlines in <a href="http://www.everymanchess.com/chess/books/Dangerous_Weapons:_The_Dutch:Dazzle_your_Opponents!">Dangerous Weapons: The Dutch</a>. However, although I succeeded finding some quite promising paths, the positions remained difficult and there was a very real risk that Black would be better prepared for these positions. There were also space issues to be taken into consideration (the book's 192 A5 pages have been utilized more fully than I have ever seen in a chess opening manual). So in the end - just before the final proofs had to be sent - I retraced a few steps, searched for moves that Williams had ignored, and was happy to find a quite promising option that could be covered within the space available. Now I look forward to analytical feedback from Dutch players.Sverre Johnsenhttp://www.blogger.com/profile/00796086172553035906noreply@blogger.com3tag:blogger.com,1999:blog-4097677957983331811.post-29897096278508646502010-04-05T10:35:00.003+01:002010-04-08T09:28:49.680+01:00Killer Chess Opening Repertoire Available<div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgkxajORlvwlZmoHNXBpvQLuyp-oKrPK4IXYACz8Or5x3tLOdUNDLurgAimtoW5t1R6xZQO5Y2lr-P9_m9rz4IpQzUauFn6H1ijFowkVp2Y73qdtaxCfo4bu-Ydbjn-vBg7PtnaNQFSkDY/s1600/killer.jpg" imageanchor="1" style="clear: left; cssfloat: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" nt="true" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgkxajORlvwlZmoHNXBpvQLuyp-oKrPK4IXYACz8Or5x3tLOdUNDLurgAimtoW5t1R6xZQO5Y2lr-P9_m9rz4IpQzUauFn6H1ijFowkVp2Y73qdtaxCfo4bu-Ydbjn-vBg7PtnaNQFSkDY/s320/killer.jpg" /></a></div>According to <a href="http://www.gambitbooks.com/">Gambit Publishing's Infopages</a>, <a href="http://www.gambitbooks.com/books/killer.html">'A Killer Chess Opening Repertoire'</a> is now available. I don't know why Gambit now has the copyrights to the book (the previous edition was an Cadogan/Everyman book). Although I am listed as a co-author I really was more of an editor as my instruction from Gambit was to leave the original content unchanged wherever reasonable. Summerscale was not involved in the update; I don't know why and presume he must be busy with other matters.<br />
<br />
What I did was mainly adding recent game references and analysis wherever appropriate. However, this in turned forced a considerable restructuring of the book, as some of the notes were already overly long. I believe this was a fortunate necessity as it made the book a more comfortable read. Now the book is 192 A5 pages - an increase of 48 pages or roughly a third of the original 1998 version. I didn't do a lot of independent analysis but I did spend a lot of hours together with Rybka on a few critical lines.<br />
<br />
Now I am quite eager to get my hands on a copy - not least because of the cover artwork which looks great from the web images. Unfortunately, I fear my copies will take some time to arrive as deliveries to Norway have taken surprisingly long time lately.<br />

He was one of the strongest players of all times and as late as in 1983, at the age of 62, he made it to the final in the Candidate finals (where he put up strong resistance against the young Kasparov). <br />
<br />
Differences in style are often exaggerated by authors and journalists. Smyslov was often said to have a harmonious or universal playing style. Well, that's probably as true for him as for almost all top players. <br />
<br />
Here is an example of him outplaying a weaker opponent, and it indeed looks simple. You may ask why I don't show a titanic struggle against Botwinnik or Kasparov. The answer is simply that I analysed this game when preparing a lesson on 1.g3, and I liked it.<br />

However, this exact position is less likely to arise from 1.e4 c5 2.g3, as then Black has 2...d5, which probably equalizes.</div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><br />
</div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><strong>3...Bg7 4.Ne2</strong> </div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><br />
</div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;">4.c3 may be slightly more flexible but after 4...Nc6, 5.Ne2 would transpose. We now have a position that could also arise from the move-order 1.e4 c5 2.Ne2 (an old Keres favourite).</div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><br />
</div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><strong>4...Nc6</strong> </div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><br />
</div>Now we reach positions that more frequently arise from 1.g3 c5 2.Bg2 Nc6 3.e4. A more independent line is 4...d6 5.c3 Nf6, when Karjakin-Carlsen, Wch blitz Moscow 2009 continued 6.d4 0–0 7.0–0 Nc6 8.h3 e5 9.Be3 cxd4 10.cxd4 exd4 11.Nxd4 Ne5 12.Nc3 Nc4 with equal chances.<br />
<br />
<strong>5.c3 </strong><br />
<br />
This can be said to be the point of White's set-up. By holding back his queen's knight, he is able to better control the d4 square.<br />
<br />
<strong>5...e5 6.0–0 Nge7 7.d3 d6</strong> <br />
<br />
Or 7...0–0 8.a3 d5 when Dorfman-Magerramov, Beltsy 1979 somewhat surprisingly continued 9.exd5!? Nxd5 10.c4!? (these ideas are well known from the King's Indian with reversed colours) 10...Nc7 11.Nbc3 Bf5 12.Ne4 Ne6 13.Be3 Ncd4 14.Nxd4 exd4 15.Bd2 h5 16.b4 and White's position had more potential.<br />

Black is untitled and not quite in Smyslov's league but a strong player who uses the tactical resources available to fight the grand old man.<br />

</div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;">You could be forgiven for assuming that this queen exchange is an admission and expect the g-pawns will be a weakness in the endgame. However, as will soon be evident, the doubled pawns can not be attacked, they neutralize Black's kingside pawns, cover some useful squares, and the extra open file proves quite useful.</div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><br />
</div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><strong>23...Qxg4 23.fxg4 Rxf1+ 24.Kxf1 Nc7 25.Kg2</strong> (Dia)</div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj4ZpUaffDgqjwv1g2l-D61-QvFesNiHGFbE1RySpJdXXxfIys5wzYWSlLZ2z2zGJZTpkOUwXgfvWc7aFl5sIfnHEn4oSb_fv134YpahBoPwSWCMVpKOgh2ec0IY8QOUqCRm9ZgWendPqY/s1600/Smyslov4.gif" imageanchor="1" style="clear: left; cssfloat: left; float: left; margin-bottom: 1em; margin-right: 1em;"><img border="0" nt="true" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj4ZpUaffDgqjwv1g2l-D61-QvFesNiHGFbE1RySpJdXXxfIys5wzYWSlLZ2z2zGJZTpkOUwXgfvWc7aFl5sIfnHEn4oSb_fv134YpahBoPwSWCMVpKOgh2ec0IY8QOUqCRm9ZgWendPqY/s320/Smyslov4.gif" /></a></div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><strong>25...g5?!</strong> </div><br />
This creates a new weakness and simplifies White's task. After 25...Nc8 26.Nd5 Nxd5 27.exd5, White's advantage is also huge, and he can combine play in the a-file with ideas of a5-a6, completely immobilizing a knight on c8.<br />
<strong>26.Nd5 Ncxd5 27.exd5 bxa5 28.Rxa5</strong><br />
<div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><br />
</div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;">White is now clearly better - maybe even winning as Black has no counterplay. </div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><br />
</div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><strong>28...e4!</strong> </div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><br />
</div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;">This probably is Black's best try, weakening c4 and taking away the e4-square from White's pieces. An example of more passive defence would be 28...Nc8 29.Nc3 Rb8 30.Na4 h6 31.Ra6 Kf8 32.Rc6 Ke8 33.Rc7 and Black is helpless.</div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><br />

</div><div style="border-bottom: medium none; border-left: medium none; border-right: medium none; border-top: medium none;"><strong>31.e5! </strong><br />
<br />
In a sense this is the counterpart of Black's 28th move, weakening c5 and gaining access to e4 again.<br />
<br />
<strong>31...dxe5 32.Kf3 Nxc4 33.Ke4 Rd8 34.Nc3 Rd7 35.Rc6 </strong><strong>Kg7 36.Rxc5 Nd6+ 37.Kxe5 </strong></div><br />
White is a healthy pawn up and has the more active pieces. <br />
<br />
<strong>37...Kf7 38.Ne4 Nxe4 39.Kxe4 Re7+</strong> <br />
<br />
39...Ke7 40.Ke5 is not better.<br />
<br />
<strong>40.Kf5</strong> <strong>1–0</strong> <br />
<br />
I am not sure whether Black lost on time or resigned in view of lines like 40...h6 41.d6 Re1 42.Rc7+ Ke8 43.Rxa7 Rb1 44.b6!

A <a href="http://www.gambitbooks.com/pdfs/183Samp.pdf">pdf sample</a> from <a href="http://www.gambitbooks.com/books/killer.html">'A Killer Chess Opening Repertoire'</a> is now available. <br />
<br />
It's just a few pages - the Table of Contents and two games featuring the Barry Attack. The first game is Hebden - Nunn, Hastings 1996/7, which gave White's opening system a lot of publicity and then it's Brousek - Rivest, corr. 2003 which is a more recent attempt to keep White's initiative alive. <br />
