Round 4 Board 2

1.d4 Nf6 2.c4 e6 3.g3 Bb4+ 4.Bd2 a5 I was aware of this variation, but had never faced it before 5.Bg2 d5 6.Qc2 6.Nf3 dxc4 7.Qc2 Bxd2+ (7...Nc6 8.Qxc4 transposes back to the current game) 8.Qxd2 c6 9.a4 b5 10.axb5 cxb5 11.Qg5 as in the first game of the Kramnik-Topalov match leads to unbalanced positions 6...Nc6 7.Nf3 dxc4 8.Qxc4 Qd5 9.Qxd5 exd5 10.0-0 Bg4 11.Be3 0-0-0 12.h3 Bxf3 13.Bxf3 Ne4 14.Rd1 f5 15.a3 Be7 16.Nc3 g5 17.Nb5 Bf6 18.Rac1 Rhe8 19.Bd2

19...Nxd2 He went for this rather quickly. I had spent a lot of time calculating captures on d4 19...Bxd4 20.Nxd4 Nxd4 21.Bxa5 Nb3 22.Bxe4 (22.Bxc7 Nxc1 23.Bxd8 Nxe2+ 24.Bxe2 Rxd8) 22...fxe4 23.Bxc7 Nxc1 24.Rxc1 Rd7 25.Bf4+ Kd8 26.Bxg5+; 19...Nxd4 20.Nxc7 20.Rxd2 g4 21.hxg4 Bg5 22.e3 Rxe3 23.fxe3 Bxe3+ 24.Kg2 Bxd2 25.Rd1 25.Rh1 fxg4 26.Bxg4+ Kb8 27.Rxh7 Bc1 28.b3 Bb2 29.Rxc7 Nxd4 30.Nxd4 Kxc7 31.Ne6+ Kc8 32.Nxd8+ Kxd8 33.Bf3 is an equal ending 25...Bg5 26.gxf5 Ne7 27.g4 c6 28.Nc3 Kc7 29.a4 Afterwards he suggested 29.Rh1 to prevent Black's next. I was trying to avoid getting my queenside pawns fixed on Black after an eventual Ne2 a4 29...h5 30.Ne2 Rg8 31.Rh1 h4

32.Re1? A horrible move that just loses. 32.Rd1 Nc8 33.Ng1 Nd6 34.Nh3 Bf6 and Black is making some progress. The engine suggests just 32. Kh2 stepping out of the tactics on the g-file 32...Nxf5 33.gxf5 Bd2+ 34.Kf1 Bxe1 35.Kxe1 Rg5 36.Kf2 Rxf5 37.Ng1 b5 38.axb5 cxb5 39.Ke3 a4 40.Nh3 b4 41.Bd1 a3 42.bxa3 bxa3 43.Bb3 Kd6 44.Nf4 Rg5 45.Kf2 Rg8 46.Ba2 h3 47.Nxh3 Rb8 0-1
