It appears that the (directly) comparable lines would be:<BR/>a) 1.Nf3 d5 2.g3 Nf6 3.Bg2 Bf5 4.0–0 e6 5.d3 h6 6.Nfd2 e5<BR/>b) 1.d4 Nf6 2.Bf4 g6 3.e3 Bg7 4.Nf3 d6 5.h3 0–0 6.Be2 Nfd7 7.e4<BR/><BR/>Here White has the extra move Be2 in the London line (b).<BR/><BR/>My gut feeling is that Black is very close to equality in both lines. But that feeling is not supported by extensive computer analysis, GM evaluations or even by intense brain activity.Sverre Johnsenhttps://www.blogger.com/profile/00796086172553035906noreply@blogger.comtag:blogger.com,1999:blog-4097677957983331811.post-33191036865928325782008-04-11T21:14:00.000+01:002008-04-11T21:14:00.000+01:00On the Chesspublishing.com Flank Openings Forum, t...On the Chesspublishing.com Flank Openings Forum, there is some discussion of this line but with the colors reversed. There has been some discussion of the move 6...e5!? after 1 Nf3 d5 2 g3 Nf6 3 Bg2 Bf5 4 0-0 e6 5 d3 h6 6 Nfd2 and IM Richard Palliser thinks that 6...e5 is sufficient enough to give black equality. Do you think playing this move as white a tempo up should give white an advantage? I also asked this same question on the d-pawn Specials Forum.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-4097677957983331811.post-12114646343661228332008-02-11T15:42:00.000+01:002008-02-11T15:42:00.000+01:00This is very interesting.

That is not a promise that I will publish anything - I just hope to have a serious look at Silman's lines.<BR/><BR/>The position is very complicated and I note that Silman is just as careful as me to deny any responsibility for analytical mistakes!Sverre Johnsenhttps://www.blogger.com/profile/00796086172553035906noreply@blogger.comtag:blogger.com,1999:blog-4097677957983331811.post-51327456534169673272008-02-09T05:03:00.000+01:002008-02-09T05:03:00.000+01:00Sverre, I asked the same question about the line o...Sverre, <BR/><BR/>I asked the same question about the line of the London System/King's Indian to Jeremy Silman as I did to you and here was his analysis. <BR/><BR/>1.d4 Nf6 2.Bf4 g6 3.e3 Bg7 4.Nf3 d6 5.h3 0-0 6.Be2 Nc6 7.0-0 Nd7 8.c4 e5 9.Bh2 f5 10.Nc3 g5 11.dxe5 dxe5<BR/><BR/>My first impression would be to play 12.Qd5+ Kh8 13.c5!? (13.Rad1 seems too slow to offer anything). And now:<BR/><BR/>13...Qe7<BR/><BR/>* 13...g4 (incredibly ugly) 14.hxg4 fxg4 15.Nd2! Nxc5 16.Qxc5 Qxd2 17.Rfd1 and I think Black is in serious trouble due to lines like 17...Qc2 (17...Qxb2 18.Rab1 Qc2) 18.e4! (Trapping the Queen and defending f2.) 18...Nd4 19.Bxe5 Nxe2+ 20.Kh1 and wins.<BR/><BR/>* 13...a5!? when both 14.Rad1 and 14.Rfd1 lead to fun positions that need a serious analysis.<BR/><BR/>14.Qc4 Qxc5<BR/><BR/>14...Nxc5 15.Nd5 Qd6 16.Nxc7 is just good for White.<BR/><BR/>15.Nd5 Qd6 16.Rad1 g4 17.hxg4 fxg4 18.Ne1 and Black's position has a lot of holes, which leads me to prefer White.<BR/><BR/>Of course, all this needs analysis and testing. Don't trust my quick, toss it out, analysis!<BR/><BR/>What do you think about his analysis?Anonymousnoreply@blogger.com
