1.e4 c5 2.Nc3 Nc6 3.g3 Diagram The Closed Sicilian has been my pet for the past years after a few pointers from NM Rich Kmiec. 3...d6 4.Bg2 Bd7 5.d3 Rb8 Black adopts a strange setup declining from playing the natural g6, Bg7; He opts instead for inmediate counter play on the queenside. 6.Be3 Nf6 7.h3 a6 8.Nge2 e5 9.Qd2 Be7 10.0-0 0-0 11.f4 Diagram After having developed; I begin with probably "The most logical" plan in this position and very thematic in this opening. 11...b5 12.f5 Nd4 13.g4 b4 14.Nd1 Ne8 He begins a very dubious idea by playing Ne8. The idea of g5 worried him and reacted incorrectly. [Fritz 8: 14...h6 15.c3 bxc3 16.bxc3 Nxe2+ 17.Qxe2 Bc6 18.g5 hxg5 19.Bxg5] 15.Nc1 f6 16.c3 Nc6 17.h4 g6 18.Bh6 Fritz catches an idea which I didn't really consider during the game. The idea is to give up the pawn on g4 for piece activity by playing fxg6 Bxg4 Nf2!? activating White's pieces for a future attack againt's white's king. [Fritz 8: 18.fxg6 Bxg4 19.Nf2] 18...Rf7 19.Nf2 Bf8 20.Be3 Diagram I saw that I could take on g6 and penetrate with the queen on h6, but since I failed to see anything concrete I decided to maintain the tension. [Fritz 8: 20.Bxf8 bxc3 21.bxc3 Rxf8 22.fxg6 hxg6 23.Qh6 Rf7 24.Nb3 Ne7] 20...Be7 21.Nh3 Qc8 22.Ne2 Rb7 23.Ng3 Qb8?! Diagram My oppponent's position has not been lost but it sure has been very difficult to play. As soon as I saw Qc8?! I knew that my opponent was running out of ideas. This plan of intending to penetrate through the b-file is very slow! which gives me time to set-up an attack against his king.24.Rf2 Rf2 defends from any penetration on b2 and also creates the posibility of playing Raf1 when I'm soon looking for a g5 break. 24...bxc3 25.bxc3 Rb1+ 26.Rxb1 Qxb1+ 27.Rf1 Qb5 Diagram Now my opponent's position only relies on whether or not he has a chance to play c4 under good circunstances. 28.g5 c4 29.d4! Diagram Trying to limit himself from any possible counter play. 29...exd4 30.cxd4 Qb4 31.Qxb4 Here with 7 minutes left to achieve move 40 and make time control I fail to consider Qc1!? with a plus. Now I decided to only go into a slightly better endgame where he now has good drawing chances. [Fritz 8: 31.Qc1 fxg5 32.hxg5 c3 33.Qd1 Ng7 34.f6 c2 35.Qc1 Bxh3 36.Bxh3] 31...Nxb4 32.Rc1 Bb5 33.a4 Bxa4 34.Rxc4 d5 35.Rc8 Kg7?? Diagram Here I have misplayed the position better was 36.exd5! with a fine position for White. Now after Rc8 I have given up my slight advantage and he has a good chance with Bd7! [Fritz 8: 35...Bd7! 36.Rc3 dxe4 37.Bxe4 Bd6 38.Bd2 a5 39.Re3 Kg7 40.Kg2 gxf5 41.Bxf5 Bc6+] 36.gxf6+ Nxf6 37.e5 Ng4 38.f6+ Nxf6 39.exf6+ Bxf6 After this mini combination winning a piece for 2 pawns with 10 seconds left I make time control and play the best move on the board h5! creating a matting net. 40.h5! Diagram After this mini combination winning a piece for 2 pawns with 10 seconds left I make time control and play the best move on the board h5! creating a matting net.40...h6 41.hxg6 Kxg6 42.Nf4+ Kh7 43.Nxd5 After all of these virtually forced moves 43. Nxd5! not with the idea of winning a pawn but even stronger.
