The longest game of the match. Anand switched to a Nimzo-Indian, forsaking the Catalan that had served him so well. His choice seemed to be vindicated as Topalov found himself in trouble in an ultra-complicated endgame with an imbalanced position. Anand made it to the winning line more than once, but faltered at the last moment. The Bulgarian's resilience paid off with a draw.
