{584MB, Fritz11.ctg} 1.d3 d5 2.Nd2 e5 3.e3 Nf6 4.Nb3 c5 5.h3 Nc6 6.Be2 Bd6 7.Nf3 h6 8.O-O O-O 9.Bd2 Be6 10.Rc1 c4 {(BvR) here black has a very good position and quite a few options to choose from (eg. 10..b5; I was 'afraid' for 11.c4, but I should not have to, e.g.11...bxc4; 12.dxc4, e4; 13.Nh4, dxc4; 14.Bxc4, Bxc4; 15.Rxc4, Qd5! and 16...g5). Instead I overlooked white's strong reply 12. Na5, expecting 12.Na1} 11.dxc4 dxc4 12.Na5! Nxa5 13.Bxa5 Qe7 { (BvR) I did not like the alternative 13...Qxa5; 16.Qxd6} 14.Bc3 Rfd8! 15.Qe1 Nd7? {(BvR) I missed the much better 15...Ne4!; e.g.16.Bxe5, Bxe5; 17. Nxe5, Nd2 winning the exchange for a pawn.} 16.Rd1 b5 17.a3 Bf5 18.Qd2 {(BvR) the positions are equal here, according to Fritz 7. But 18.Bb4 was needed to simplify, rather than placing the white queen in the firing line and black an extra move.} Nb6 19.Qc1 a5 {(BvR) here we come, pawns marching forward? At least, that was the intention. It only happened towards the very end of the game.} 20.Rfe1 b4 {(BvR) Fritz does not like this move: 21.Rxd6,Qxd6; 22.Bxe5, Qc6; 23.Bd4 and black will be Ok} 21.axb4 axb4 22.Bd2? {(BvR) now black will have to lose stuff..} Qc7 {(BvR) threatening 24.c3. Tempting to play was 22..Ra2?, but white could have reacted strongly with 23.e4!, Bxe4; 24.Bxc4!. Hence 22.Qc7, instead.} 23.e4 Bxe4 24.Bxh6 {(BvR) white is more or less lost here, so he might as well go for broke and sacrifice a bishop. 24. Be3 would have been more prudent, though. Most likely less exciting though...} gxh6 25.Qxh6 Bxc2 26.Bd3 Bxd3 27.Rxd3!! Bf8 {(BvR) A fantastic rook sacrifice. After a 20 minute thought, however, I chickened out: 27...cxd3; 28.Re4!, f5; 29.Rh4, Qg7; 30.Qe6+, Kf8; 31.Qxf5+, Ke8; 32.Rh7. I did calculate to this point, and concluded that I was lost. Unfortunately, Fritz 'tells' me that I was wrong and that I have the miraculous escape: 32..Ra1+; 33.Kh2, e4+; 34.g3, Bxg3!!; 35. fxg3; Qxb2 checkmate. Or 35.Kg2, exf3+; 36.Kxf3, Qf8. What a pity that I am only a 'mortal' player'...} (27...cxd3 28.Re4 f5 29.Rh4 Qg7 30.Qe6+ Kf8 31.Qxf5+ Ke8 32.Rh7 Ra1+ 33.Kh2 e4+ 34.g3 Bxg3+) 28.Qg5+ Bg7 29.Rde3 f6 30.Qg3 Nd5 31.Re4 Nf4 32.Nh4 Rd3 33.Qg4 Rd4? {(BvR) allows white to be back in the game to a degree (-1.73). Pushing the c-pawn would have been the most direct way for black to win: 33...c3; 34.Rxb4, c2; 35.Rc1, Rd8 and white has to give a rook to prevent the c-pawn to promote} 34.Rxd4 exd4 35.g3 {35.Nf5 (best move) is +2.0 better for black, whereas 35.g3 is about +4.} Nd3 36.Re2 Rd8 37.Nf5 Ne5 38.Qh5 d3 39.Re4 {(BvR) Here white had only 8 minutes and black 6 minutes on the clock. Understandably, that not the best moves were played from here on.} d2 40.Ne3 Qf7 41.Qd1 Qg6 42.Rf4 Bh6 43.Nf5 {(BvR) with the threat 44.Ne7, with less than 4 minutes on black's clock} Rd7 44.Nxh6+ Qxh6 45.Kg2 Qg6 46.f3 {giving black +31 advantage (Fritz)} Qd3 47.Rxf6 Rf7 48.Rxf7 Kxf7 49.Kf2 Qxf3+ 50.Qxf3+ Nxf3 51.Ke2 c3 52.bxc3 bxc3 {(BvR) b3 better, of course with both players on1 minute} 53.Kd1 Ng1 54.h4 Nh3 55.Ke2 Nf2 {(BvR)Thanks Harrison for some great firework in an interesting game} {#R}
