A New Barry Idea

These days I am reading Cyrus Lakdawala’s “Play the London System”. It’s an interesting read and I will probably return to the subject.

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 Killer Chess Opening Repertoire’ (and concluded that Summerscale’s 7.Ne5 probably still is White’s best try):

7...Qa5

This is the most popular reply and the only one mentioned in the book although 7...Nbd7!? has been played by Khalifman among others.

8.Nd2!

The exclamation mark is by Lakdawala and the move probably is White’s best try.

8...Qxc5

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.

9.Nb3 Qb6 10.Nb5!

Again the exclamation mark is by Lakdawala. White has also tried 10.0-0, 10.a4 and 10.Nxd5?!.

10...Ne8! (Dia)

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.

11.Qxd5

What else? Black was threatening ...e5 as well as ...Bxb2.

11...Bxb2 12.Rb1 Bg7 13.0–0 Nc6 14.c4 (Dia)

Not 14.N5d4? e5! 15.Nxc6 bxc6 and Black wins.

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):
A: 14...Bf5 15.Rbd1 Nf6

Or 15...Nb4 16.Qd2 Na6 17.Nc3 Nf6 18.Qc1 Rac8 19.Be5 Be6 20.Bd4 Qb4 = L.B.Hansen-Djurhuus, Reykjavik 1995.

16.Qc5 e5 17.Bg3 Ne4 18.Qxb6

Rybka claims that 18.Qa3 is equal. That may well be right; the position looks somewhat strange and I find it hard to evaluate.

18...axb6 19.Ra1 Rfd8  and in Akselrod-Salinnikov, Tomsk 2003 Black was clearly better thanks to his activity.

B: 14...Nf6 15.Qc5 e5! 16.Bg3 Ne4 (Dia)

This too looks fine for Black who is active and has the bishop pair.
a) 7.Qxb6 axb6 18.a3 Bf5 =+ Rogers-Fedorowicz, Groningen 1990.

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.






Conclusion:
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?

Play the London - pdf Extracts

Just briefly noting that there are now pdf-extracts from Lakdawala's 'Play the London System' at Everyman's chess book site.

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.

Play the London System Announced

Everyman Chess has now officially announced 'Play the London System' by Cyrus Lakdawala. It is scheduled for September 2010 in the US and October 2010 in Europe, but Everyman hasn't exactly stuck rigorously to their publishing scheme the last year. At 192 pages it will be be of similar size as our 2005 work.

With this information I will take new contact with Gambit Publishing and suggest they publish an updated version of 'Win with the London System' early in 2011. There almost certainly will be an update but its extent is unclear (as is the timing).
