1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. cxd5 Nxd5 5. e4 Nxc3 6. bxc3 c5 7. Be3 Bg7 8. Bc4 Nc6 9. Ne2 O-O 10. O-O Qc7 Black frees d8 for his rook, to increase the pressure against the d4 pawn.
11. Rc1 White takes rook away from the dangerous a1h8 diagonal and indirectly defends his bishop on c4 which is eyed by the black queen.
11... Rd8 12. Bf4 White tries to take advantage of black's queen placement to disrupt black's position. The queen doesn't have many safe squares e.g. 12... Qb6?? 13. Rb1 Qa5 14. Rb5 Qa3 15. Bc1 and it is trapped, or
12... Qa5 allows 13. Qb3 , black's knight no longer has the use of the a5 square.
12... e5 13. Bg5 Rd7 This move looks slightly odd but this is the best square for the rook. It must stop white's dpawn marching up the board to d6 e.g. 13... Rf8 14. d5 Na5 15. d6! Qd7 16. Bd5
14. d5 a6 It may be that black does not need to make this move. He can play 14... Na5
attacking the bishop, then c4 b5
15. Qd2 Na5 16. Bd3 b5 At this stage it is clear how the game will play out. White will be pushing on the kingside, taking advantage of most of black's pieces being on the other wing, while black's counterplay will be on the queenside with his dangerous pawn wedge
17. Bh6 Bh8 This left f8 looking weak
18. f4 c4 19. Bb1 The bishop would have been better on c2. I was worried about black's queenside pawns, or even the bishop on h8, attacking the pawn on c3 as I intended the pieces currently defending c3 would be joining in the kingside attack.
19... Nb7 20. f5 Rd6 The start of a clever defensive plan by black.
21. Ng3 a5 22. Rf3 Raa6 23. Be3 Bd7 24. Rcf1 Be8 25. Qf2 Fritz likes 25. Qb2 here, switching attention to to black's queenside pawns.
25... Bg7 26. fxg6 hxg6 27. a3 Bf8 The bishop on a3 is weak and black looks to attack it quickly
28. h4 I decided to let the pawn on a3 go, thinking I had enough play on the kingside to compensate, although to be honest I wasn't sure.
28... Rd7 29. h5 Bxa3 30. hxg6 Rxg6 31. Nh5 This move wins the exchange, 31... Be7 covering f6 allows 32. Rxf7
31... Bc5 32. Nf6+ Rxf6 33. Rxf6 Bxe3 34. Qxe3 Qc5 35. Kf2 Qxe3+ 36. Kxe3 Nd6 37. Bc2 Kf8 Black allows 38. Re6 which I just did not see. Fritz gives the line 38... b4 39. cxb4 axb4 40. Rff6 Nb5 41. Ba4 Nc3 42. Bxd7 Bxd7 43. Rb6 b3 44. Rb4 Ke7 winning for white.
38. Ra1 1/2-1/2
