Mamedyarov takes a half point lead into the final round of the FIDE Grand Prix in London. Mamaedyarov held Wang Hao to reach 6.5/10 and his rivals Grischuk (who probably came closest to a win), Topalov and Gelfand remain half a point further back after draws. The only decisive game of the day saw Hikaru Nakamura end his nightmare four game losing streak with a win against Anish Giri who misjudged a sharp ending.

After four losses in a row Hikaru Nakamura stopped the rot and beat Anish Giri in round 10. Nakamura didn't have anything much in the way of an advantage but both players kept things complicated and eventually Giri made a fatal misjudgement of the power of his pawns against a bishop and went down to defeat (he may actually be lost here too in which case Giri's error is in the position below).

46... Bf4 was also possible but black saw no reason to prevent Nakamura's ambitious play but now it seems he probably should have.

Position after 52.Bxd7

52...Kxd7?

This is more than black's position can take white's bishop proves to be more than enough for the pawns. 52... Kxf7 and whilst white should be a bit better I don't think it will amount to a win.

I kept changing the strength of the above comment from good winning chances for white to the above. (The ChessMind Blog of Dennis Monokroussos thinks Giri is lost after Kxf7 too. It wasn't so much I was relying on the computer evaluation as I followed the game without computers in the afternoon before looking at them later. It's that even I could see the precise winning moves after Kxd7 which after Kxf7 there looked to be some hope, although maybe not as much as I thought.

53. Bxc5 h5 54. f8=Q Rxf8+ 55. Bxf8

I believe this is clearly winning for white because he can eventually stop the black pawns and the only way black might be able to win is with e4 but this would give white three running pawns which will in turn be unstopable.

55...h4 56. Bh6 g4 57. Bg5 h3

57... e4 58. dxe4 h3 59. Bf4 {is no kind of alternative.

58. Bh4 Kd6 59. Bg3

Bishop takes care of black's running kingside pawns, it's all over.

59...Ke6 60. Ke2 Kd6 61. Kd2 Kc5 62. Bxe5 Kb4 63. Kc2 Kxa5 64. Kb3 Kb6 65. Bxd4+ 1-0

Leader Shakhriyar Mamedyarov held Wang Hao on the black side of a rather strange Caro-Kann Classical which saw lively tactics and exchanges to a drawn endgame.

Alexander Grischuk was pushing as black for some time against Rustam Kasimdzhanov but it was always a difficult task. Maybe he missed a better chance on move 36. He quickly traded into a drawn ending shortly afterwards.

Leinier Dominguez Perez and Vassily Ivanchuk drew a Ruy Lopez Steinitz Variation in 40 moves that was probably level throughout.

Veselin Topalov tested Michael Adams in a side-line of the Queen's Gambit which was a bit of a technical challenge but the game was probably balanced throughout.

Peter Leko possibly had a small edge in a Sicilian against Boris Gelfand but it never amounted to very much and the game was drawn in 59 moves.
