1.e4 c5 2.Nc3 Nc6 3.g3 d6 4.Bg2 e5 5.d3 Nf6 6.Nge2 Bd7 7.Bg5 [Committing to castling was worth considering. 7.0–0 ] 7...Be7 8.Bxf6 Bxf6 9.Nd5 a6 Unconstructive use of time. 10.Nxf6+ Unable to decide what to play, this move is not very good. 10.c3 is suggested by fritz. [10.c3 Be6 11.0–0 b5 12.f4] 10...Qxf6 [10...gxf6 I considered this recapture, with play down g file, but white can simply castle q-side and f pawns are weak. e.g: 11.Nc3 Qa5 12.Qf3 0–0–0 13.0–0–0 with an advantage to white.] 11.Qd2 g5 This is an active move but black has many pawn weaknesses now, together with the c5,e5 already played. 12.Nc3 Nd4 Bad for black, by allowing Nd5. Ne5 should be prevented, e.g. 12...Be6 [12...Be6 13.Nd5 Bxd5 14.exd5 Nd4 15.0–0–0 0–0–0 16.c3 Nf3 17.Qe3 g4 18.Bxf3 gxf3 for example.] 13.Nd5 According to the computer, a definite plus for white. 13...Qd8 Parrying Nf6+ & Nc7+ 14.c3 natural 14...Bh3 Tactically incorrect. My guess is this is an attempt to complicate things in an uncomfortable position. 15.cxd4 White retains an advantage with this clear line, but there was a MUCH better move, giving three times the advantage. Fritz gives 15.f4 [Naturally not 15.Bxh3 Nf3+; 15.f4 Bxg2 Only move to avoid losing a piece. 16.Qxg2 Ne6 17.fxe5 dxe5 18.0–0 Material is even but fritz approximates this as E2.5. Black's pawns are very weakened, and white has fantastic play down the f file in coordination with his knight.] 15...Bxg2 16.Rg1 Bf3 17.dxe5 [17.dxc5 is exactly the same as black has nothing better than 17...dxc5] 17...dxe5 18.Qe3 g4 A better defence existed, avoiding loss of exchange but still leaving black with a difficult position. [18...Bg4 19.Qxc5 Rc8 the point is, now Nc6+ is no longer a threat as after Qxc6, Qxc8+ is impossible because of Bg4's defence of Rc8 20.Qb4 Be6 21.Qxb7 Bxd5 22.exd5 0–0 23.f4 a human might prefer something more solid (e.g. 23.Kf1 Rb8 24.Qxa6 Qxd5 25.Qc4 Qd6 26.Kg2 Rb4 27.Qc1 Qd5+ 28.f3 g4 29.Qg5+ Kh8 30.Qf6+ Kg8 31.Rgf1 Rxb2+ 32.Kh1 Rc8 33.Qg5+ Kf8 etc. fritz considers it a likely draw, probably due to likely perpetuals by defending side etc) 23...exf4 24.gxf4 Re8+ 25.Kf1] 19.Qxc5 f5 Definitely an error. This opens the board more for a killing attack by white. 20.Nc7+ Kf7 21.Qc4+ I was most happy with this move out of all in the game. I couldn't see a simple solution to convert the advantage: e.g. 21.Nxa8 right away, 21...Qxd3, with threat of mate on e2. However, it occured to me after looking at my options for some time just to play Qc4+, improving my position before taking the exchange. 21...Kg6 22.Qe6+ [22.exf5+ was more accurate, making life even worse for the white king. e.g.: 22...Kxf5 23.Nxa8 Bd5 24.Qc5 Bf3 25.Nb6 Qxd3 26.Qc4 Rd8 27.Qxd3+ Rxd3 28.Rc1 h6 29.a4 a5 30.Rf1] 22...Qf6 23.Qxf6+ This time my inoptimal move could have thrown away the game. After 23.ef+ there is no chance for white, but now there is a chance of holding. [23.exf5+ Kg5 24.Nxa8 Rxa8 25.Qxf6+ Kxf6 26.Kd2 Kxf5 27.Rac1 Rd8 This was better, but almost the same position occured in the game anyway.] 23...Kxf6 24.Nxa8 Rxa8 25.exf5 The critical reply is apparantly Rd8 25...Kxf5 [25...Rd8 26.Kd2 e4 27.Ke3 Rxd3+ 28.Kf4 Rd5 29.Rac1 Rxf5+ 30.Ke3 Rd5 31.Rc3 Rb5 32.Rc2 It's still unconvincing that black can hold.] 26.Kd2 Rd8 27.Ke3 Rd4 28.h3 h5 29.Rac1 Be4?? A blunder in a bad position. 30.hxg4+ 1–0
