The 2015 tournament featured Fabiano Caruana, Viswanathan Anand, Vladimir Kramnik, Levon Aronian, Sergey Karjakin and Hikaru Nakamura. The tournament was held from 13-19 February 2015 at the Hotel Savoy Baur en Ville in Zurich.
A Blitz Tournament determined the colors distribution on the first day of the tournament (Friday, February 13, 2015). After the opening, 5 classical games were played following by another 5 rapid games on the last day of the tournament. The rules stated that wins (2 points) and draws (1) count double for classical games, with a draw before move 40 “punished” by an extra rapid game.
Vishy Anand and Hikaru Nakamura ended up with 9 points. For determining the winner, although it was said before that the previous games between two must decide the result, they changed the rules midway and asked the players to play an armageddon game in which Hikaru Nakamura won with the black and ended up as the tournament winner.
