BDO , Round 5, 20.8.09
Analysed by Hairulov and Rybka 3!
1. e4 c5 2. Ne2 A rarely seen move order but usually transpose into the main line 2...a6 3. c4 I'm not sure about this move but it look rather unusual. Probably white decide to go away from theoretical duel and just wan to play "chess" !? 3...b5 4. d3 g6 5. Be3 Bg7 6.
Qd2 d6 7. Nbc3 bxc4 8. dxc4 Nc6 9. f3 Rb8 10. Nf4 Qa5 11. Rc1 Nd4 12. Bd3 e6
13. O-O Ne7 14.Nh3 Nec6 15.b3? black seems to blunder a pawn with this move. Black can play 15...Nxb3 16.axb3 Rxb3 17.e5 Bxe5 and white's knight on c3 will lose.
15... Nxb3 16. axb3 Rxb3 Now my new silicon "friend" Rybka 3 give a wild line 17. e5 Bxe5 18. Be4 d5 19. cxd5 Bxc3 20.Qd1 (20. Rxc3 Qxc3 21. Qxc3 Rxc3 22. Bd2 Nd4 23. Bxc3 Ne2+ 24. Kf2 Nxc3) 20...Nd4!
17. e5 Bxe5 18. Be4 18...Nd4?! The correct move is 18... d5! 19. cxd5 Bxc3 20. Qd1 (20. Rxc3 Qxc3 21. Qxc3 Rxc3 22. Bd2 Nd4 23. Bxc3 Ne2+ 24. Kf2 Nxc3) 20... Nd4 Now the game look unclear or should i called it "dynamic equality" because white have extra piece but black have extra 3 pawns. 19. Kh1 f5 20. Bb1 0-0 21.Bf4 21...Bh8 Quiet an unusual retreat by Mas. Why not retreat the bishop to it normal square at g7? Probably Mas want to keep his black's bishop or sometime call - the Gufeld's Bishop. if he played 21...Bg7 white probably will exchange it with 22.Bh6 As a former GM Eduard Gufeld student, he must have admire his teacher passion toward the black square bishop. 22.Qe1 Bb7 23.Bxd6 Rd8 Now white can play 24.Be5 with the idea of 26.Bxd4 and the 27.Qxe6+ with strong attack 24.Bf4 Qa3 Mas mantain the pressure against white's c3 knight. 25.Bg5 Re8 26.Nd5 Bc6? A serious mistake by Mas. The correct move is the wild knight sacrifiece 26...Nxf3! . Now after the text move, he will be down more material 27.Ne7+ Rxe7 28.Bxe7 Re3 29.Bxc5 1-0 Mas resign after 29...Rxe1 30.Bxa3 black's is simply a rook down.
