Round six tie-break

Alexander Grischuk (Russia) and Vassily Ivanchuk (Ukraine) exchanged victories in their rapid games (25 minutes plus ten second per move), then Grischuk took the upper hand in the two ten-minute games, spurred by a capital blunder in a possibly winning position by Ivanchuk.

In the first game Grischuk (above right), in his own words, played well: "I got an opening advantage and then transposed to a very unpleasant ending for Black, which Vassily was unable to hold."

Grischuk: "In the third game I played in Polgar style: my combination was absolutely unsound, but all the pieces on the board started to hang, and my opponent resigned in three moves. This is so typical for Judit!"

The blunder on move 33 that sent the Ukrainian veteran packing


Lost this match by a single move: Vassily Ivanchuk

Thursday, September 15 is a free day at the World Cup. The matches Grischuk-Svidler and Ivanchuk-Ponomariov begin on Friday, September 16. Grischuk and Ivanchuk will play White.

Peter Svidler and Alexander Grischuk are very good friends. In Spring 2011 Svidler was Grischuk's second during the Candidates Matches, where Grischuk also reached the final. Ruslan Ponomariov and Vassily Ivanchuk played a World Championship match in January 2002, almost ten years ago. Will Ivanchuk manage to avenge his loss? The winner of this match earns the last spot in the 2012 World Championship Candidates (the first two spots are already secured by Grischuk and Svidler).
