Magnus Carlsen won again in the second round of the Biel ACCENTUS GM tournament moving to 6/6 (three points for a win). Alexander Morozevich also won after a miscalculation by Maxime Vachier-Lagrave, Caruana-Pelletier was drawn. Round 3 1pm UK time on Wednesday: Pelletier-Vachier-Lagrave, Shirov-Caruana, Morozevich-Carlsen.

Magnus Carlsen won his second game in the row to move to 6 points with a rather easy win against Alexei Shirov. The players followed Anand-Van Wely from 2005 until Carlsen played an obvious computer improvement. By this stage I think this was not the position Shirov wanted because once Carlsen played his improvement, which was the computer's first choice, Shirov faced a hard battle to stay in the game. Carlsen appeared to have many ways to keep a large advantage and he converted this to a win after 33 moves and only 70 minutes of thinking time.

Magnus Carlsen

Position after 15.Nh6

A first new move but one that Fritz 12 at least thinks is the best. Carlsen played much faster than Shirov and at no point did black's position look satisfactory so it is odd he played this line.

15.Ne3 with an eventual draw was Anand,V (2786)-Van Wely,L (2679)/Monte Carlo MNC 2005 and indeed this does look fine for black almost immediately.

Maxime Vachier-Lagrave was doing well out of the opening against Alexander Morozevich but then badly miscalculated with 28.Ng5+? and after that there was no way back.

Maxime Vachier-Lagrave

Position after 28.Ng5+?

A strange and losing blunder, Vachier must have made a simple miscalculation but it is hard to see what he was hoping for.

Finally Fabiano Caruana tried for a long time against Yannick Pelletier a pawn up in the Rook and pawn ending but had to settle for a draw on move 59.

Three points for a win, one for a draw.
