1. e4 c5 2. c3 Nf6 3. e5 Nd5 4. d4 cxd4 5. cxd4 e6 6. Nf3 d6 7. Bc4 Be7 8. Qe2
O-O 9. O-O b6 10. Nc3  Nxc3 11. bxc3 Bb7 12. exd6 

White plan is to occupy the e5 square. This is a very effective plan against which black has no answer.

Bxd6 13. Ne5 Nd7

Black should look for counter-play. 13... Nc6 14. f4 Ne7 and place the kight on f5. white is unlikely to play g4 as it will weaken the long white diagonal

14. f4 Rc8 15. Bd2 Rc7 16. Bd3 Nf6 17. Rae1

A good centralizing move but white can also try to open lines on the queen-side with a4. white is just waiting to see what black will do.

17...Re8 18. Bb1 g6 19. Rc1 Ba3 20. Rcd1 Bb2 ?!

This allows white to take the bishop pair. ...Be7 is better but the position is roughly equal after that.

21. Nc4 Ba6 22. Bd3 Bxc4 23. Bxc4 Nd5 24. Bb5 Ree7 25. c4 Nc3

25... Bxd4+ 26. Kh1 Nf6 27. Bb4 Red7 ({There is a
nice tactical motif after} 27... Re8 28. Bxe8 Nxe8 29. Bc3 Rd7 30. Rxd4 Rxd4
31. Qe5 +- the rook is pinned because if it moves there is a mate on h8 ) 28.Rd3 {There is no hurry, the rook on d7 is not going anywhere.})

26. Bxc3 Bxc3 27. Qe3 Ba5 

the idea is to stop an a4-a5-a6 push, but the bishop is pretty much a spectator here. 27... Bb4 28. a3 Bd6 29. a4 Bb4 30. Qb3 Qd6 =

28. Ba6

If white plays for a win he can try 28. Rc1 Qc8 29. c5 to create a passer.

28... Qd6 29. a3 Qd8 30. Kh1 Rcd7 31. Rd3 Rd6 32. Rfd1 Red7 33. h3 Qh4 34. Kh2 Rd8 35. g3 Qh5 36. Qe5 Qh6 

36... Qxe5 37. fxe5 R6d7 38. Bb5 Rc7 += White has the advantage as he can prepare to push d5. The bishop on a5 is totally out of play.

37. Bb7 Qf8 38. h4 

White has the space advantage in the centre. This is not enough to win so he prepares to open another battle front, the king-side with h4-h5. Black has to stop this.

38...h5 39. Ba6

If 39. d5 Re8 40. Bc6 Rc8 41. Kg2 (White cannot break the blockade on d6 nor can he open the d-file with dxe6 satisfactory results.)

39... R6d7 40. Bb5 Rd6 41. Ba6 

White signals that he is okay with a draw. The  pre-tournament strategy was to play safe and not take un-necessary risk against the stronger players (IMs and GMs). Let them try to beat you and if they over-extend themselves, than punish them accordingly. This strategy worked well in the Brunei tournament and it worked here as well.

41... Qe7 42. Qe4 Qc7 43. Qe5 Qc6 44. Qb5 Qa8 45. Qe5 Qc6 46. Qb5 Qc7 47. Qe5 Qe7 48. Qe4 Qd7 49. Qg2 Kf8 50. Qb7 Qa4 51. Bb5 Qc2+ 52. Qg2 Qxg2+ 53. Kxg2 

With the exchange of queens, the position is clearly drawn. This did not suit the GM who needed the win to get back amongst the prize contenders.

53...Ke7 54. Kf3 Rc8 55. Ke4 Rc7 56. Re3 Rc8 57. Ba6 Rc7 58. Bb5 Kd8 59. Red3 Ke7 60. Ba6 Rdc6 61. Kf3 Kf6 62. Rb1 Rxc4 ??

 There is not enough compensation but I bet black is banking on the time trouble to hustle
his young opponent.

63. Bxc4 Rxc4 64. Rbd1 Ra4 65. Rc1 b5 66. Rc5 b4 67. Rc4

Black is only fighting for a draw after 67... Rxa3 68. Rxa3 bxa3 69. Ra4
Bc3 70. d5 ! a5 71. Rxa3 Bb4 72. Rd3

68. Rb3 Kd6 69. Ke4

69. axb4 Bb6 70. Ke4 Ra2 {black rook is active}

69... f6 70. Rd3 !?

(70. axb4 f5+ 71. Kd3 Bb6 72. Rc8 Kd5 73. Rg8 Ra1 {is not so clear and black has some chances})

70... f5+ 71. Kf3 Kd5 72. Rc5+ Kd6 73. axb4 Bxb4 74. Rb5 a6 75. Rb8 Kd5 76. Rd8+ Bd6 77. Rb3 

This wins but white could have played Re3 straight away. (77. Re3 Rxd4 78. Re5+ Kc6 79. Rxe6 a5 80. Rxg6 a4 81. Rg5 +- {the a-pawn is not dangerous at all. White always has Ra8})

77... Kc6 78. Re3 Rxd4 79. Rxe6 a5 80. Rxg6 a4 81. Ra8 

As noted, Rg5 also wins

 Kb5 82. Rg5 Rd5 83. Rxh5 Bc5 84. g4Rd3+ 85. Ke2 Rg3 86. Rxf5 a3 87. g5 a2 88. h5 Kc4

(88... Rg1 89. h6 a1=Q 90.
Rxa1 Rxa1 91. h7 Rh1 92. g6

black is helpless against the queening white pawns

}) 89. Rxc5+

white finds the simplest win.

 Kxc5 90. Kf2 Rh3 91. Kg2 Rxh5 92.
{Kd5 Re2 and white wins easily.} 1-0
