Essent: Mamedyarov - Topalov

Today the first round in the Crown Group of the 2006 Essent was played. Key game was the first performance of Topalov after he lost his world title to Kramnik two weeks ago.

Mamedyarov played an excellent game, keeping Topalov under pressure troughout the game. Especially after the less accurate 22... f5?! Topalov had to defend with precision. Mamedyarov seemed to squeeze out a win until he played 28 Bg5?!. It looked spectacular but the key variations all led to a draw. Instead 28.Qh5! would have held the initiative.

However, Topalov cracked under the pressure after having found most of the forcing drawing line. Move 35... Nf4? was a clear blunder and Mamedyarov finished the game with computer like precision.

Judit Polgar returned from maternity leave and beat Sokolov in a long manouvering game. Actually Sokalov lost after producing two weaker moves and a blunder in an equal position (42... Ng7?! instead of Rd8!=, 43... Qe7?! instead of Qc7!= and 45... h5?).
