Nf3 O-O 6. Be2 e5 7. O-O Nc6 8. d5 Ne7 9. Nd2 {This is the main alternative to 9.Ne1.} 9... a5 { The most popular reply.} 10. a3 Nd7 11. Rb1 f5 12. b4 {Black's 9th move succeeded in holding this back for a while, but now White is back on track on the queenside. I like to have the initiative!} 12... b6 {Black can ignore this the attack at a5 and play 12...Kh8, preparing to use the g-file for a kingside onslaught.} 13. f3 f4 {It is still not too late to opt for 13...Kh8.} 14. Na4 axb4 15. axb4 g5 {In this footrace, White has a headstart.} 16. c5 Nf6 17. cxd6 cxd6 18. b5 Bd7 19. Nc4 Nc8 {An ugly move, but the b-pawn must be protected.} 20. Ba3 {Another ugly move is now forced, to defend the d-pawn.} 20... Ne8 21. g4 {With this move I try to keep the kingside closed. Black has to capture en passant here, or face a long battle with no counterplay at all.} 21... fxg3 22. hxg3 g4 23. Bc1 {I keep an eye on the dark squares of the kingside this way.} 23... gxf3 24. Bxf3 Nf6 25. Bg5 Ra7 26. Rf2 Rb7 27. Rb3 Ra7 28. Rb1 Rb7 29. Rb3 Ra7 {Hmm, I am not getting anywhere!} 30. Rb4 {This is the right move. Next I will sacrifice the b-pawn and then I will be the one attacking on kingside.} 30... Kh8 31. Qf1 Bxb5 32. Rxb5 Rxa4 { So Black has a pawn. Big deal. I can sacrifice more than that!} 33. Bg2 h6 34. Bh4 {The bishops step aside so that the big pieces can get into the act.} 34... Qe8 35. Bxf6 Rxf6 36. Rxf6 Qxb5 37. Re6 { Black's pieces are so useless that I can afford to part with the knight.} 37... Kg8 {37...Qxc4 38.Re8+ Kh7 39.Qf5+ or 37...Rxc4 38.Qf7 Rc1+ 39.Kh2} 38. Bh3 Rxc4 39. Rxh6 {There goes the last barrier! Now nothing can stop me.} 39... Bxh6 40. Be6+ Kh8 41. Qf6+ {Black resigned, because there is no way to prevent mate. If you don't believe me, try making Gambit white then let Gambit show you!} 1-0
