1.e4 c5 2.Nf3 d6 3.Bb5+ Bd7 4.Bxd7+ Qxd7 5.c4 Nf6 6.Nc3 g6 7.d4 cxd4 8.Nxd4 Bg7 9.h3 Three days ago Sergey played 9.f3 against Nakamura Qc7 10.Qe2!? White mostly plays this way: 10.b3 Qa5 11.Bd2 Nxe4 12.Nxe4 Qe5 13.Qb1 f5 14.Bc3 Qxe4+ 15.Qxe4 fxe4 The position gets less complex and it seems to me that Black equalizes without many problems. 16.Nb5 Bxc3+ 17.Nxc3 Nd7 18.Nxe4 Rc8 19.Kd2 Nc5 20.Rhe1 Nxe4+ 21.Rxe4 Rf8 22.f3 Kd7 23.a4 a5 24.Rae1 Rf7 25.Ke3 1/2-1/2 Spasov,V (2594)-Mamedov,N (2587) Konya TUR 2011 10...Nc6 11.Nc2 0-0 12.0-0 a6 13.Bd2 Sergey is just trying to develop his pieces. The position is of course about equal. e6 14.Rac1 Rfe8 15.Be3 Ne5 16.Na3 16.b3 b5! 16...Rac8 17.b3 Qa5 18.Nab1 d5! 18...b5?! is dubious because after 19.cxb5 axb5 20.Qxb5 Qxb5 21.Nxb5 Nxe4 22.f3! Ng3 23.Nxd6 Ne2+ 24.Kh1 Rxc1 25.Rxc1 Nxc1 26.Nxe8 Nxa2 27.Nxg7 Kxg7 28.Bd4 f6 29.Bxe5 fxe5 30.Kg1± White can get a winning endgame in a more or less forced line. 19.f4 19.cxd5 exd5 20.exd5 Nxd5 21.Nxd5 Qxd5 22.Rxc8 Rxc8 23.Rd1 Qe6 24.Na3 would be just equal. 19...Nc6 20.e5 Nh5 21.Qf2?! Although this move led White to victory, in my opinion a better move would be 21.g4, with a draw as a probable outcome. The move that White chose to play could provoke huge problems for him. However, Black did not realise that opportunity. 21.g4 Ng3 21...d4 22.gxh5 dxe3 23.Ne4∞ 22.Qf2 Nxf1 23.Bb6 Qb4 24.Bc5 Qa5 25.Bb6= 21...d4! 22.Bxd4 Nxd4 23.Qxd4 g5! 23...Ng3!? was also interesting, but 23...g5! is much stronger 24.Rf3 Bf8 25.Kh2 Nf5 24.fxg5 Bxe5 25.Qf2 Bf4? Black played very reasonably and strongly, but unfortunately now Hou Yifan misses an opportunity to take an initiative. 25...Ng3! 26.Rfd1 26.Qxf7+ Kh8 27.Rf2 Qc5 28.g6 hxg6 29.Qxg6 Qe3! 30.Qc2 Rcd8 26...Red8 and probably White is in big trouble here. 26.Ne4!± Bxc1 27.Rxc1 White chose a more positional play. 27.Qxf7+ Kh8 28.Rxc1 Ng7 29.Nbd2± 27...Qe5 28.Re1 Kh8 29.Nbd2 Red8 30.Nf3± White had a very nice position, and I didn't have any doubts that Sergey would gain victory in this round. Qf4 31.g3 Qc7 32.Qb2+ Ng7 33.Ne5 Qb6+ 34.Kg2 Rc7 35.c5 Qb4 36.Qf2 Rd5 37.Nd6 Nf5 38.Nexf7+ Rxf7 39.Nxf7+ Kg7 40.Nd6 Nxd6 41.Qf6+ Kg8 42.Qxe6+! Kg7 42...Nf7 43.Rf1! Rd2+ 44.Kh1+- 43.cxd6 also wins, but 43.Qf6 would mate Black in nine moves. For example: 43.Qf6+ Kg8 44.Qd8+ Kg7 44...Kf7 45.Re7+ Kg6 46.Qg8+ 45.Re7+ Nf7 46.Qxd5 43...Qxd6 44.Qxd6 Rxd6 45.Re7+ Kg8 46.Rxb7 Rd2+ 47.Kf3 Rxa2 48.Kg4 Rd2 49.h4 a5 50.Kh5 Rd6 51.Ra7 Rb6 52.Kg4 Rb4+ 53.Kh3 Rb5 54.Kh2 Kh8 55.Kg2 Kg8 56.Kh3 Kh8 57.Kg4 Rb4+ 58.Kf5 Rxb3 59.h5 Rf3+ 60.Kg4 Rf8 61.Rxa5 Rb8 62.h6 Kg8 63.Kh5 Kf7 64.Rf5+ Ke6 65.Rf4 Rb3 66.Rf6+ Ke7 67.Ra6 Kf7 68.Ra7+ Kg8 69.Ra8+ Kf7 70.Rh8 1–0
