Mark Crowther comments:

Veselin Topalov took hold the the Wijk aan Zee A group with a brief win against Magnus Carlsen. His strong exchange sacrifice caused Carlsen many problems and although he started along the best line it proved impossible to find all the good moves and pretty soon he was flat lost. This extends Topalov's lead to a full point over the field.

Part 2

Viswanathan Anand continued his recovery with a win against Sergey Karjakin. Anand played a line investigated in San Luis and which was also investigated in correspondence games before. The line seems fully satisfactory for black. White decided to go for a fortress with rook and knight hopefully keeping out the Queen and King. However Anand showed that by zugzwang he could win a pawn on the kingside. He then by his own admission demonstrated terrible technique which included dropping his b-pawn. I implied that he was still winning at the end but couldn't afford to drop any more pawns. As it was 62.Rd5 makes life easy as Anand queens and then takes the a-pawn (not the knight) when the win is easy. Karjakin didn't wait and immediately resigned.

62.Rd5? Anand has made many errors and the game could still end in a draw although there are still chances to win. But this move allows Anand to win the h-pawn and with it the position. 0-1

Peter Svidler followed his game against Vladimir Kramnik at Wijk two years ago. In that game he forgot his preparation and lost quickly. In order to "put the variation to bed" Svidler repeated the variation but his opponent Radjabov only vaguely remembered the game and it was agreed drawn without leaving the prior game.

Tiviakov drew with Navara in a sterile game that never wavered from equality.

Alexander Motylev didn't make any progress against Vladimir Kramnik's Petroff and the game was agreed draw in 17 moves.

Alexei Shirov and Ruslan Ponmariov fought hard but they coudn't overcome the opposite coloured bishops and the game was draw in 47.

After various adventures Loek van Wely obtained some winning chances against Levon Aronian. He fell into a trap which immediately turned the position into a draw.
