The wrong choice of ending
27.01.2010 – In round 7 in Wijk, Nigel Short was within touching distance of a win over Ex-World Champion Vladimir Kramnik. In the position in the diagram he had to decide whether to exchange queens or to gobble up another pawn with Qxc5. Short chose 50.Qxc5, but after 50...Be6! 51.g4 Bxf5 52.Qxf5 Qb2+ the activity of the black queen turned out to be the decisive drawing factor, despite Black being two pawns behind. But how should the minor piece ending after 50.Qxf6 gxf6be evaluated? Can the extra pawn be made to tell in the struggle of knight against bishop? Yes, says GM Karsten Müller in ChessBase Magazine Online.

Wijk aan C
28.01.2010 – Seeing all these superstars at the Corus Tournament 2010, one can easily forget that also the C-group provides a wealth of highly interesting chess. For example this game, where White after Black's last move 23...Bg7-f6 had to parry the attack on his queen. The strike 24.Rxf5 in your opinion leads to what?
A) advantage for White;
B) balanced play;
C) advantage for Black.
The solution is here, but first ponder over it with a larger version of the diagram.
