[Koetsier,David]
1.e4 e5 2.Nf3 f5 3.Nxe5 Qf6 4.Nc4 fxe4 5.Nc3 Qf7 6.Ne3 d5!?
I’m working on this move recently. [6…c6 7.d3 exd3 8.Bxd3 d5 9.0–0 Bd6 Prob. the only way to keep things going for black. (9…Bc5?! 10.b4 Bd6 11.Nexd5 cxd5 12.Re1+ Ne7 13.Nb5 Bxb4 14.Rb1!+-; 9…Be6 I still like the look of this move. It prevents all sacrifices on d5 and black can continue his development by 0–0–0 etc.. 10.Re1 Ne7 11.Ne2 Nd7 12.Nd4 0–0–0 13.Ng4 Bxg4 14.Qxg4 But white is clearly better.) 10.Re1 (10.Nexd5 cxd5 11.Nb5 Qd7!? Koetsier.) 10…Ne7 11.Nexd5 !Kosten. 11…cxd5 12.Nb5 0–0 13.Nxd6 Qxf2+ 14.Kh1 Bg4 15.Qd2 Qh4 16.b4 Strautin’s move. And now: 16…Nbc6 17.Bb2 Rad8! (17…Rf2 18.Qc3 Qh6 19.b5 Raf8 20.Bf1 ! Bucker 20…Nd8 21.Qg3 Rxc2 22.Ba3 Bh5 Melchor’s idea. But: I like Rybka’s 23.Rxe7! and the black position is gone. 23.Rxe7+- Qf6 24.Nf5 Qxa1 25.Qxg7+ Qxg7 26.Rxg7+ Kh8 27.Bxf8 Rf2 28.Bd3 Be2 29.Bxe2 Rxf5 30.Bd3 Rxf8 31.Rxh7+ Kg8) 18.Qc3 Rf6 19.Nxb7 Rdf8 20.b5 R8f7 21.Qc5!?N Koetsier (21.bxc6 Rh6 22.h3 Bxh3) 21…Rh6 22.Qg1 Nb4 23.Nc5! (23.Ba3 I still haven’t work out this position…but I have the feeling that white will be on top. 23…Nxd3 (23…a5? 24.Bxb4 axb4+-; 23…Bd7 24.Bxb4 Qxb4 25.Nc5 Nf5 26.Bxf5 Bxf5 27.Re8+ Rf8 28.Rxf8+ Kxf8 29.a4 Not easy to defend but black has Certain drawing changes.) 24.cxd3 Rg6 25.Qe3 Be6 26.Bxe7 Rxe7)
Can white take the pawn with 25.Qxa7 instead of 25.Qe3?
25…h6 is forced and now 26.Qe3.
How can black continue his attack in this position?
26…Bf3 27.gxf3 Nf5 28.Qe8+ Kh7 29.Qxf7 Qh3 30.Qxg6+ Kxg6 31.Rg1+ Kh7 32.Rg2 Qxf3 33.Kg1 Qxd3 unclear.
23…Nxd3 (23…Rf8 Mb this move is better 24.Be5 Nf5 25.Rab1 Nxd3 (25…Ng3+ 26.Bxg3 Qxg3 27.Re3+-) 26.Nxd3 d4 27.Qf2 Ne3 28.Qxh4 Rxh4 29.Bxd4 Nxc2 30.Re4 Nxd4 31.Rxd4) 24.Nxd3± Be6 (24…Rg6 25.Ne5 Nf5 26.h3 Ng3+ 27.Kh2 Ne4 28.Rxe4 dxe4 29.Nxg6 hxg6 30.Qe1) 25.Bd4 Nf5 26.Bf2] 7.Nexd5 [7.Ncxd5?! Be6 (7…c6 8.Nc3 Nf6 9.d3 Bb4 10.Bd2 (10.Be2 Be6 (10…0–0?! 11.0–0 exd3 12.Qxd3 Na6 13.a3) 11.0–0 exd3 12.Qxd3 Nbd7„) 10…0–0 11.Be2 exd3 12.Bxd3 Bxc3 13.Bxc3 Nd5 14.0–0 Nxc3 15.bxc3 Be6 16.f4± Pecis-Melchor 5th Wch final Latvian 2005 ) 8.Bc4 Bd6 9.0–0 Nc6 10.f3 exf3 11.Rxf3 Qd7 12.d4 0–0–0 13.c3 Melchor-Ardila , cr. LADAC Thema 2008] 7…Be6 8.Bc4 Na6 Best move. 9.Bxa6 [9.d3 0–0–0! 10.Bxa6 Bxd5 (10…bxa6 11.Nf4 exd3±) 11.Nxd5 Qxd5 12.Bc4 Qf5; 9.b3 Bucker.] 9…bxa6 10.Ne3 Nf6 11.f4!? 0–0–0 Koetsier 12.Qe2 Kb7 13.b3 [13.b4!? Looks very dangerous but black is Ok!] 13…Bd6 14.0–0 h5!© Black brings his pawn up to h3 with compensation. 15.Nc4 Bc5+ 16.Kh1 Bg4 17.Na5+ Kb6 18.Qc4 Qxc4 19.Nxc4+ Kb7 20.h3 Be6 21.Na5+ Kc8 22.Nc6 Rd6 23.Ne5 h4With active play. So to me it looks like the Gunderam variation is still much alive! The resurrection of LATVIAN! 24.Na4 Bd4 25.c3 Bb6 26.Nxb6+ axb6 and white is a little bit better.
