Nxc3 8. bxc3 Bb7 9. e6! and numerous games show that it's easier to attack than defend in this position 8. axb5 Frequently played with a flourish - White often thinks Black has blundered 8... Nb6 9. Be2 Be7 10. O-O O-O 11. Be3 Bb7 A typical position for this line. After the b5 pawn is exchanged, the 'weakness' of the c-pawns is difficult to exploit - the c7 pawn is very well hidden and the weak c4 pawn is balanced by the backward d4 pawn. Also, while on c4, the pawn cramps White's forces and makes it difficult to organise any Kingside play 12. Qc2 Qd7 13. Bg5 Bxf3 14. Bxf3 Bxg5 15. Bxa8 Nxa8 16.

The exposed nature of the White King helps me do just this. 33... Qb7! 34. Kh2 c5! 35. dxc5 Bxc5 36. Ra5? 36. Ra2 was forced, but this was a time trouble error 36... Bxf2 Now Black is winning 37.
