[Chirila, Ioan]

1.d4 Nf6 2.c4 e6 3.Nc3 Bb4 4.Bg5 A sideline that steers the game into unclear waters, the type of position that I was striving to achieve against my solid opponent [4.e3 ; 4.Qc2 Are just a few other posibilities] 4...c5 5.d5 h6 6.Bh4 Bxc3+ [6...exd5 7.cxd5 d6 8.e3 Nbd7 9.Bd3 0-0 10.Nge2 Ne5 11.0-0 Chirila,I- Yang, D was played just a few months before this game] 7.bxc3 d6 8.e3 e5 9.Qc2 [9.Nf3 Bf5 10.Nd2 Nbd7 11.e4 Bh7 12.f3+/= White has space advantage and the bishop pair, these two factors should allow him to have a better game] 9...g5 10.Bg3 e4 taking away the f3 square for my knight, but at the cost of opening my black square bishop and offering him a clear target on d6. Nevertheless, it was hard already to find a clear plan for black. 11.f4! Qe7 [11...exf3 12.Nxf3 0-0 13.Bd3 Qe7 14.0-0~~ ] 12.Be2 Kf8?! [12...Kd8 I think this was better, the king is much safer on the queen side than on the king side, especially after the 'f' file will open] 13.Nh3 Bxh3 14.gxh3 gxf4 [14...Nbd7 15.0-0 Rg8 16.Kh1+/= ] 15.Bxf4 Nbd7 16.0-0 Ne5 17.Kh1 Re8 18.Bg3 [18.Bxe5 This was my initial thought, and probably the better move. I did not want to commit by giving away my strong bishop, but I think that white simply has an almost winning position due to the strong pressure on the f file 18...Qxe5 19.Rf4 Rg8 20.Raf1 Rg6 21.Bd1 Kg7 22.h4 h5 23.Rf5 Qe7 24.Bxh5+- ] 18...Nf3 [18...Rg8 19.Bh4 Nf3 20.Bxf3 exf3 21.Rxf3 Qe4 22.Qxe4 Nxe4 23.Raf1 Rg7~~ ] 19.Bxf3 exf3 20.Rxf3 Ne4 21.Raf1 Rh7 22.Rf4 Rg7 23.Bh4 Ng5 [23...Qe5? 24.Rf5 Qxc3 25.Qxc3 Nxc3 26.Bf6+- ] 24.e4 Kg8 25.Bxg5 hxg5 26.Rg4 f6 27.Rf5 Rh7 28.Qf2 Kg7 29.h4 Rh5 30.hxg5 fxg5 31.h4 Reh8 32.Kg1 R8h6 33.Qf4 Rg6 34.Rfxg5 Rhxg5 35.Rxg5 Qe8 36.Qxd6 Rxg5+ 37.hxg5 Qxe4 38.Qf6+ Kh7 39.Qh6+ 1-0
