Welcome to the Chessdom live commentary of Corus 2009! The games to be commented depend on your votes (more info). Submit your vote for round 4 here. The audience voted for Carlsen - second with 18%, behind So with the impressive 34% - so we'll follow the game of the young Norwegian star for third consecutive day. His games are very spectacular, this tournament being no exception so far, so that choice is no surprise. In spite of his two starting draws there was a lot of fighting and complications in both games so his fans shoul not be disappointed.
1.d4 d5 2.c4 c6 3.Nf3 Nf6 4.e3 As Movsesian has vast experience in Slav Defense with 4...a6, Caslsen has obviously prepared himself in a sideline, which by the way is very popular recently and may turn inato one of the main lines.
4... Bg4 5.Qb3 Qb6 6.Nc3 e6 7.Nh4 Bh5 8.h3 Still no new moves are played but Black spent 15 minutes until now.
8... Nbd7 (8... Bg6 was played in Bilbao in Topalov - Aronian.)
9.g4 Bg6 10.g5 White is looking for other solution instead of the standard Nxg6.
10... Ng8 The Knight usually retreats to this square in similar situations dreaming for Ng8-e7-f5.
11.Nxg6 hxg6 12.Qc2 Ne7 13.Bd2 Nf5 14.cxd5 cxd5 (14... exd5 leaves the Knight without sufficient support and the situation may become dangerous after 15.O-O-O)
15.Nb5 Bd6 16.Qa4 a6 17.Rc1 Ke7 18.Nxd6+ Nxd6 19.Bd3 Rhc8 Carlsen has the advantage of the Bishop pair but with so static pawn structure that is not essential.
20.Ke2 e5 The correct decision. 21.dxe5 Nxe5 favors Black while after e5-e4 he would be out of danger.
21.Qb4 e4 22.Bc2 Qxb4 23.Bxb4 a5 24.Bxd6+ Kxd6 25.f3 After the exchanges the resulting situation should be estimated as equal.
25... exf3+ 26.Kxf3 Nf8 This Knight could go to 'b6' or 'c6' as well but Movsesian likes it at 'e6'. (26... Nb8 planning Nb8-c6 followed by doubling the Rooks on the 'c' file.)
27.Bd3 Ne6 28.h4 Rxc1 Else White Rooks could be doubled on the 'f' file.
29.Rxc1 Rh8 30.Kg4 Re8 31.Bb5 Rg8 Preparing f7-f5.
32.Rc3 f5+ 33.Kg3 Rf8 34.Bd3 f4+ 35.exf4 Nxf4 36.Kg4 Nxd3 37.Rxd3 Rf2 38.Rb3 Kc6 39.Rc3+ Kd6 Draw agreed. Black got very solid position after the opening. Carlsen tried everything in order to undermine the defensive build but to no avail and the draw seems to be the just result. 1/2
