BC Closed/Vancouver (5.1) 2001

1. d4 d5 2. Nc3 c6 3. e4 dxe4 4. Nxe4 Bf5 5. Nc5 Qb6 #The reason why I played this move was because I saw it recommended by Karpov as the simplest way to equalize. Its drawback is that I have to develop a queen too early. It can be justified though, as 1) the queen cannot be easliy harrassed from b6 2) it makes it harder for White to develop pieces and the queen puts pressure on b2 and d4 However, if White manages to develop without any time loss, my position should be worse. 6. Nf3 Nf6 6... e6 was obligatory. I preferred the text move because I thought that I could possibly get a chance to play e7-e5 in one move. This is a very superficial approach to position 7. Ne5 (7. Nb3 Nd7 8. Bd3 Bg6 9. O-O Ngf6=) 7... Bxc5 (7... Nf6 8. Nc4 Qc7 9. g3 Nd5 10. Bg2 Bxc5 11. dxc5 O-O 12. O-O= Rublevsky-Luther, 1992 ) 8. dxc5 Qxc5 9. Nc4 7. Bd3 Bxd3 8. Nxd3 e6 9. O-O Be7 10. Be3

10... Qd8 The queen returned, and White has a firm control over e5 and c5. 11. Re1 O-O 12. Qe2 Alex has spent more time than me in the opening and this paid back: I did not realize how dangerous this passive position can be for me, and gradually allowed White to gain a nearly decisive advantage 12... Nbd7 13. Rad1 Rc8 14. c4 a6 I decided to prepare b7-b5 in order to fight for the d5 square 15. Nde5 Here I sank into thought, because after 15...Qc7 16. Bf4 Nxe5 White has several reasonable choice and I was scared of all of them 15... Qc7 15... Nxe5 16. dxe5 Nd7 appealed to me less 16. Bf4 Nxe5 17. Nxe5 I traded off another pair of pieces, but White's remaining pieces are more and more active. 17. Bxe5 17. dxe5 17... Qd8 18. Rd3 Nd7 19. Nxd7? I was thinking that I would lose after 19. Rh3 This seemed to be a natural follow-up to White's previous move 19... Nxe5 20. Qh5! h6 21. Bxh6 Ng6 I think I did not even consider this move, as I did not see 22...Bh4 ( and here I only saw 21... g6 22. Qxe5 Bf6 23. Qf4 and I hoped that I could hang on in this position 23... Qxd4 (23...

Rxd5 Qc6 #around this moment we both had about 5 minutes left and I offered a draw, thinking that 1) my disappointed opponent would take it as largest part of his advantage is gone 2) objectively position should be drawn, even if White has a small initiative 25.

White has a more active king and rook, he can now try to push his kingside pawns in several ways 44... Ke7 45. g5 Another plan was 45. f4 45... fxg5 46. hxg5 Ke8 46... Kd8 I had planned to transfer the king to c7, but when actually getting to this position decided to keep king in the center 47. Ke5 Ke7 47... Kd8? 48.
