[Rybka 2.2n2 32-bit (9s), M.Otero]

B41: Sicilian: Kan Variation: 5 c4 1.e4 c5 2.Nf3 a6 The O'kelly variation of the Sicilian. I should have played the Najdorf, since this opening is not recommended against strong master level players. 3.c4 Setting up the Maroczy bind. White makes it difficult for Black to make a freeing pawn break. 3...e6 4.Nc3 Qc7 5.d4 cxd4 6.Nxd4 Nf6 7.Bd3 Last book move. 7...Nc6 I should have played 7...Bb5 pinning the c3 bishop which is what the opening recommends. 8.Nxc6 [8.Nb3 Ne5 9.f4 Nxd3+ 10.Qxd3 d6 11.0-0 Be7 12.e5 dxe5 13.fxe5 Nd7 14.Bf4 Nxe5 15.Qg3 f6 16.Rae1 0-0 17.Ne4 Bd7 18.Nxf6+ Bxf6 19.Bxe5 Bxe5 20.Rxf8+ Rxf8 21.Qxe5 Qxc4 22.Nc5 Bb5 Abramovic,B (2460)-Mijailovic,Z (2335)/Nis 1993/EXT 1997/0-1] 8...Qxc6N I wasn't sure whether to take back with ...bxc6 or with the Queen. Decided on taking with the Queen with hopes of having b7-b6 in the future. [8...bxc6 9.Be3 Bd6 (9...Bb7 10.Rc1 Qd8 11.e5 Ng8 12.0-0 Ne7 13.Ne4 Nf5 14.Qf3 Be7 15.c5 0-0 16.Qh3 g6 17.Bd2 a5 18.g4 Ng7 19.Bh6 f5 20.exf6 Bxf6 21.g5 Be7 22.Bxg7 Kxg7 23.Qh6+ Kg8 24.Rfd1 Harnois,C (1880)-Swiercz,S (1670)/Hyeres 2002/EXT 2003/0-1 (71)) 10.h3 Bf4 11.Qf3 Be5 12.Qe2 c5 13.0-0 Bb7 1/2-1/2 Le Quang,K (2235)-Van Uytven,E (2110)/Belgium 1997/EXT 1998] 9.0-0 d6 I played this move in fear of 10.e5 with my f6 knight not having a good square to go to except g8. 10.Be3 Developing the bishop 10...Be7 Getting ready to castle. 11.Rc1 After this move my Queen began to feel vulernable. 11...0-0 Getting the King to safety. 12.Qf3 e5 Preventing e5, and closing up the h7-b1 diagonal to the White bishop.. Black has a new backward pawn: d6. Rybka doesn't like this move. Eval went from .27 in White's favor to .82. [12...Nd7 13.Qg3= ] 13.Bg5 Be6 I spent a lot of time on this move. I was torn between the aggressive 13...Bg4 attacking the Queen and the text move. I decided against Bg4 because the queen could go to 14.Qg3 and then if my f6 knight fell, the Queen would be ready to snap up the bishop. 14.Nd5 I wasn't expecting this from White. I figured I had no choice but to take the dangerous knight since 15.Ne7 was a Queen - King fork. I also looked at 14...Qd7, but then White had 15.Nb6 forking the my Queen and rook. 14...Bxd5 15.exd5 I thought White would take with the c-pawn, with a triple attack on my Queen.. White has the pair of bishops 15...Qe8 I looked at 15...Qa4, but 16.a3 refuted this move, and I felt my Queen would be vulnerable in the corner. Eval went from .60 to 1.60, this is the critical point in position. [>=15...Qd7!? is an interesting alternative 16.Bf5 Qd8+/= ] 16.Bxf6+- Bxf6 17.Qf5 Threatening mate on the next move with 18.Qh7#. 17...g6? The only way to save the game cost me the bishop. The game is over at this point, but I decided to play to see how she would finish me off. [>=17...e4 I would have been able to take White's bishop in this variation. I considered this candidate, but not deep enough to show that I would have been able to take the bishop on the 5th ply. I should think as deep as possible in critical positions such as this. 18.Bxe4 g6 19.Qxf6 Qxe4 20.Qxd6 b5+- ] 18.Qxf6 Rd8 Protecting the d-pawn. [18...Qd8 19.Qxd8 Rfxd8 20.f4+- ] 19.h4 Launching a pawn storm to get rid of the King's defenses. [19.f4 makes it even easier for White 19...exf4 20.Rce1 Qa4+- ] 19...e4 An aggressive move, that was not well thought out (there wasn't much left). I thought of 19...h5, but then 20.g4 would be very problematic. [19...Rd7 20.f4+- ] 20.Rfe1 White quickly puts an end to any hopes. Black resigns. 1-0
