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.

10... Qd8 The queen returned, and White has a firm control over e5 and c5.

I had a hole in my calculation: Only here did I realize that the intended 52... Re7+?? loses to 53. Rd7 53. b5 axb5 53... Rxa4 54. b6 Rg4 55. Kxb7 a5 56. Ka7 Rxg5 57. b7 Rb5 58. Rd7+ Ke6 59.

35. Kd4? back in 2004, I thought that g5 wins as well, but now (2007) it looks like that's not the case: 35. g5 Ke6 36. h3 h6 (36... g6 37. h4 Kd6 38. Kd4) 37. Kd4 hxg5 38. Kc5 Ke5 39. Kb6

5... Nh6 this is the most logical move here as I don't want to shut down my bishop with e7-e6, and at the same time can't put the knight on f6.
