Coming into today's round with a one point lead and just two rounds to go, and with the black pieces, Magnus Carlsen's job was a rather Hippocratic one: first, do no harm. He kept things under control against Wesley So and achieved a draw without too much trouble. It was a good result against a player who had until the previous round looked like his main challenger for first place.
Instead, that honor goes to his two-time world championship match opponent, Viswanathan Anand, who defeated Shakhriyar Mamedyarov on the white side of a Spanish Four Knights. First Anand made progress in the center, and then sacrificed the exchange for a pawn and loads of kingside play. He enjoyed a serious advantage, but didn't manage to make the most of it. Several moves before time trouble Mamedyarov managed to equalize, though proving and maintaining it wasn't going to be easy. Short of time, he bashed out his last two moves, and they were both mistakes. He was losing at this point, but even so his next two moves were also errors, and it was time to resign after White's 43rd move.
In other games: Vladimir Kramnik finally stopped the bleeding and even managed to win his game, against Maxime Vachier-Lagrave, and got back to -1 in the tournament. Michael Adams also improved his hitherto unfortunate tournament with a win, in his case over Anish Giri. Finally, Rauf Mamedov continued his very solid tournament with a draw against Fabiano Caruana.
One round remains; here are the pairings:
- Mamedyarov (3.5) - Adams (3)
- Caruana (4.5) - Anand (5.5)
- Carlsen (6) - Mamedov (3.5)
- Vachier-Lagrave (3) - So (4.5)
- Giri (3) - Kramnik (3.5)
