Maxime Vachier-Lagrave assumed the advantage against Wesley So after the American was forced to sacrifice a knight for two pawns. However, in the forced sequence of moves many pieces were exchanged and the position simplified with all remaining pawns being on the kingside.
It took a lot of patient maneuvering from black to finally destroy white’s pawn mass and achieve a victory and qualification to the 5th round.
Peter Svidler played a good game with black to hold the ground and earn a much needed draw with black against the tournament’s top seed Veselin Topalov. In the final position black is even objectively winning, but he made a practical decision and agreed to opponent’s draw offer.
At the press conference Svidler shared that he lost several consecutive games with black pieces against the Bulgarian. He broke the negative record at the best possible moment as the result enabled him to advance to the World Cup quarterfinals.
Local star Shakhriyar Mamedyarov and Hikaru Nakamura comfortably drew their games with black pieces, against Fabiano Caruana and Michael Adams, respectively, to also reach the stage of best-eight.
In the Chinese derby the young prodigy Wei Yi was able to strike back against Ding Liren and equalize the score in the match, which will now be decided in the tie-breaks.
The matches Radoslaw Wojtaszek vs Anish Giri, Sergey Karjakin vs Dmitry Andreikin and Dmitry Jakovenko vs Pavel Eljanov are also to be settled in quick-play on Tuesday afternoon.
The total prize fund of the 2015 FIDE World Chess Cup is 1,6 million USD. In addition, the tournament also awards two places in the 2016 Candidates Tournament, part of the FIDE World Championship cycle.
The players are getting 100% of their prizes, not 80% as most are quoting. This is because the Organizers paid the FIDE share on top of the Prize Fund.
