1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Bf4 Be7 5.e3 0-0 6.a3 c5 7.dxc5 Bxc5 8.Nf3 Nc6 somewhere around here, my opponent offered a draw. However, because we were outrated on all boards, I realized that every point and chance to create a winning chance will be helpful for the team. I've always liked to play fighting chess anyway:) 9.Qc2 Qa5 10.Rd1 Be7 11.Be2 dxc4 12.Bxc4 Nh5 13.0-0 Nxf4 14.exf4 a6 [more commonly played is 14...g6 as was played in a battle between titans 15.g3 Rd8 16.Rxd8+ Qxd8 17.Rd1 Bd7 18.f5!? gxf5 19.Qd2 Qb6 20.Qh6 Be8 21.Ng5 Bxg5 22.Qxg5+ Kf8 23.Qh6+ Kg8 24.Qg5+ Kf8 25.Rd6 Qc7 26.Qh6+ Ke7 27.Qh4+ Kf8 28.Qh6+ Ke7 29.Nb5 Qa5 30.b4 Nxb4 31.Rxe6+ fxe6 32.Qxe6+ Kd8 33.Qf6+ Kc8 34.Qxf5+ Kd8 35.Qf6+ Kc8 36.axb4 1-0 (36) Kramnik,V (2759)-Carlsen,M (2772)/Dortmund 2009/CBM 131] 15.Ne4 provoking a weakness in Black's kingside. 15...h6!? [once again, probably better was 15...g6 ] 16.Ba2 here, I saw a number of attractive ideas but I decided to be consistent . 16...Rd8 [16...Qc7 meets the unpleasant 17.Ne5 which hinders Black's q-side development.; 16...Nb4?? 17.axb4 Qxa2 18.Rd4! inevitably trapping the Black queen.] 17.Rxd8+ Qxd8 18.Rd1 Bd7 19.Bb1 Kf8? planning to run away from White's onslaught, and prevent Nc5 ideas. [forced was 19...g6 but 20.Nc5 Bxc5 21.Qxc5 Rc8 22.Qe3 still gives White unremmitting pressure on the k-side e.g 22...Kg7 23.h4! ] 20.Ng3 [now 20.Nc5 doesn't work as well due to 20...Bxc5 21.Qxc5+ Qe7 ] 20...g6 21.f5! exf5 [21...gxf5 22.Qd2 Ke8 23.Qxh6 Bf6 24.Re1|^ ] 22.Qd2 f4?! [more stubborn is 22...Ke8 23.Qxh6 Bf6 24.Ba2! but Black has to endure a long, tough defensive task.] 23.Qxf4 Kg7 24.Qd2 [also possible was to go to a much better ending with 24.Ba2 Qe8 25.Bxf7 Qxf7 26.Qxf7+ Kxf7 27.Rxd7 ] 24...Qb6 now Black seems to have everything in control because both 25 Qxd7 and 25 Qc3 do not work for White but wait, let check other candidate moves... 25.Bxg6! a destructive blow which escaped Black's radar [25.Qxd7 Rd8 ; 25.Qc3+ Bf6 ] 25...Rd8 26.Bf5 Be8 [26...Bc8 27.Bd3 Bg4 28.h3 Bxf3 29.Nf5++- Kg8 30.Qxh6 Bf8 31.Ne7+ Nxe7 32.Qh7# ] 27.Bd3 Kg8 28.Qxh6 Qxb2 Diagram 29.Nd4 interference tactic! 29...Qxd4 [29...Bxa3 30.Bh7+ Kh8 31.Be4+ Kg8 32.Ngf5 Bf8 33.Ne7+ Nxe7 34.Qh7# ] 30.Bh7+ Kh8 31.Bf5+ Kg8 and Black resigns. 32.Rxd4 Nxd4 33.Qh7+ Kf8 34.Qh8# 1-0
