39th Olympiad Khanty-Mansiysk 2010 Khanty-Mansiysk/Russia (1), 22.09.2010

1.d4 Nf6 2.c4 e6 3.Nf3 Bb4+ 4.Bd2 Bxd2+ 5.Qxd2 d5 6.g3 0-0 7.Bg2 Nbd7 8.Qc2 c6 9.Nbd2 Qe7 10.0-0 e5 11.cxd5 Nxd5 12.e4
White's plan is to play his center majority against black's queenside majority.

[The usual move is 12...N5b6 ]

13.Rfe1 exd4 14.e5 Nd5 15.Nxd4 N7b6 16.f4! Nb4 17.Qe4
White has achieved what he wanted and is clearly to be favored.

17...Rd8 18.N2f3 Bg4 19.Rad1 Bxf3?
Why play this without being forced to?

20.Bxf3 Qc5

[Black would still be in big trouble after 20...Nxa2 21.f5! Nd5 22.f6! and his position would collapse after 22...gxf6?! 23.Nf5! Qf8 24.Qh4 b6 25.Bxd5 Rxd5 26.Nh6+ Kh8 (26...Kg7 27.Qxf6# ) 27.Qxf6+ Qg7 28.Nxf7+ Kg8 29.Qxc6 ]

21.e6! fxe6 22.Kh1 Qd5 23.Qe3 Qxa2 24.Nxe6 Rxd1 25.Rxd1
The threat of Qe5 is very tough to meet.

25...Qxb2? 26.Nd8!
This lovely move wins by force.

26...Qf6 27.Qe8+ Qf8 28.Qe6+ Kh8 29.Nf7+ Kg8

30.Rd8! Rxd8 31.Nxd8+ Kh8 32.Nf7+ Kg8 33.Ng5+ Kh8 34.Qe4 g6 35.Qd4+ Qg7 36.Qxb4?
Winning a piece and no doubt the game, but he had a stronger continuation all the same. [36.Qd8+ Qg8 37.Qf6+ Qg7 38.Nf7+ Kg8 39.Nh6+! Undoubtedly the move that Carlsen missed. 39...Qxh6 40.Bg4! and the threat of Be6 is unstoppable.]

36...h6 37.Ne4 Nd5 38.Qa3 b5 39.Qc5 b4 40.Qxc6 Qa1+ 41.Kg2 Ne3+ 42.Kf2 Qd4 43.Qe8+ Kg7 44.Qe7+ 1-0
