The 7th game of World Chess Championship at Sochi was a make-or-break affair for the Indian challenger. Vishy Anand had to avoid a loss in any case after blowing up a straightforward winning chance in Game 6 on Saturday. But Anand waded into troubled waters in the Berlin Defense and needed to sacrifice his bishop for two pawns to prevent Carlsen from overpowering him. After that, the Game continued endlessly with Carlsen trying to break Anand’s position but the challenger held on to his ground. The 7th game marathon lasted over 6 ½ hours, before the gentlemen shook hands over the board and settled for a draw.
