KL Open 2008, 19.12.2008
1.d4 d5 2.c4 c6 3.Nc3 e6 4.e4
The Marshall Gambit .Now the main line runs 4...dex4 5.Nxe4 Bb4+ 6.Bd2 (6.Nc3 saves the pawn but is not considered dangerous) Qxd4 7.Bxb4 Qxe4+ 8.Be2 with sharp and unclear play.
4...dxe4 5.Nxe4 Nd7 Tirto avoid the main line 5...Bb4+ 6.Bd2 (6.Nc3 saves the pawn but not the critical choice ) 6...Qxd4 7.Bxb4 Qxe4 8.Be2 6.Nf3 Ngf6 7.Nc3 Bd6 8.Bd3 0–0 9.Bg5 9...Qc7 9...e5 ! break the centre is better considering white has not fully develop yet. 10.Qe2 Bf4 probably better for black is to complete his development first with 10..b6 and later Bb7 11.h4!? Aggressive reply by Julio. Alternative 11.Bxf4 Qxf4 which is a typical computer move 11... h6 12.g3! 12...Bd6 12...hxg5? would blunder a piece after 13.hxg5 13.c5 Be7 14.0–0–0 In the spirit of Kasparov and Topalov ! Many would probably choose the safer move 14.Bf4 Qd8 and then 15.0–0–0 ...but not Julio. He has shown from move 11. that he mean business! 14...b6 15.Bf4 Qb7 16.g4 Consistent. Black continue to play aggressively16... Nd5 black would be wise not to accept the pawn after 16...Nxg4 because white will have a dangerous initiative after 17.Rhg1 h5 18.Nh2 Ndf6 (18...Nxh2? would lead into a losing position after 19.Qh5! ) 19.f3 Nxh2 20.Qxh2 17.Nxd5 cxd5 18.c6 Stronger is the immediate 18.g5! 18... 18...Qxc6+ 19.Kb1 e5 20.Rc1 Qf6 21.Bg5!! Probably the most beautiful move from the game (tournament!?) 21... hxg5 22.Bh7+! Another brilliant continuation 22...Kh8 23.Bf5 gxh4 24.Rxh4+ Qxh4 25.Nxh4 Bxh4 26.Rh1 g5 27.Rxh4+ gxh4 28.Qe3
