1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.Nc3 dxc4 5.a4 Bf5 Rock solid. Wang Yue plays the rock solid Slav.
6.Ne5 Not a surprise, Topalov chose this main move from the World Championship match.
6...Nbd7 7.Nxc4 Nb6 8.Ne5 a5 Wang Yue probably thought that the ending Anand had gone for was too solid for him and chose one of the other main systems. The third main system was played on the next table, in Bacrot-Anand.
9.e3 [The other critical move, 9.f3 was chosen by Topalov against the same opponent in Sofia last year. He then won a brilliant game, but this time apparently both players had found an improvement for Black.]
9...Nbd7!? This move is becoming popular due to the efforts of the top Chinese players (all experts on the line) that switched from g6 after Wang Yue has lost twice to Grischuk.
10.Bd3 Topalov tries to get some advantage with simple play, but Wang Yue showed him that it's not so easy. [10.Qb3!? is critical, trying to punish Black for his knight moves back and forth. But if Topalov didn't choose it, there must be a reason for this. The following line seems critical and was played in the latest game, Hammer-Felgaer, from the Olympiad in Khanty. 10...Nxe5 11.dxe5 Nd7 12.e4 (12.Qxb7!? ) 12...Be6 13.Qxb7 Rb8 14.Qa7 Nxe5 15.f4 Nd7 16.f5 Bb3 17.Bf4 Ra8 18.Qb7 e5! 19.fxe6 Bxe6 with unclear play.]
10...Bxd3 11.Nxd3 Qb6! New move. Bu Xiangzhi played 11...Qc7 this year in Aeroflot, got under pressure, but also drew. The point of the move is that it prevents e4. So it's not clear for White what he should do now. Topalov finds an interesting solution... [11...Qc7 12.Qb3!? e6 13.e4+/= 1/2-1/2 Rodshtein,M (2622)-Bu Xiangzhi (2673)/Aeroflot 2010]
12.Ra3!? creative, but it seems that it doesn't give White any objective edge. [After the standard 12.0-0 e6 it's not clear how White should proceed in order to fight for any little advantage.]
12...e6 13.Rb3 Bb4! It seems a little tricky to put the bishop under the pin, but White doesn't have time to exploit it.
14.0-0 c5 An essential move, that had to be played here or after short castle.
15.dxc5 Nxc5 16.Nxc5 Qxc5 17.Na2 Now Topalov gets the bishop, but no advantage. Black is well developed and Wang Yue is in time to change everything.
17...0-0 18.Rd3 Rac8 Black could have played the position differently (for example b5!?), but Wang Yue wanted to just change everything, to keep it safe.
19.Nxb4 Qxb4 20.b3 Qc5 21.Bb2 Qc2! Just in time, otherwise White might have got some pressure.
22.Bxf6 Qxd1 23.Rfxd1 gxf6 24.Rd7 b5! The Chinese super-GM is defending very energetically and precisely, though for a player of his class such moves are played automatically.
25.Ra7 Rc3! 26.Rxa5 Rb8! Very exact, not giving Topalov any hope to press.
27.Ra7 Rxb3 28.a5 Ra3 29.g4 b4 30.a6 b3 31.Rb7 Ra8 32.Rdd7 b2 33.Rxb2 R3xa6 34.Rbb7 Rf8 35.Kg2 1/2-1/2
