After losing with the Petrov in game two, Adams instead played his usual 2...Nc6. Kasimdzhanov played the exchange variation of the Ruy Lopez, as he had against Grischuk in round five, and they followed theory until Adams' novelty 12...f5. White exchanged pieces and played against Black's weakened queenside, a typical plan in this variation. Adams came under considerable pressure, but it seemed he may be able to hold White off until, in the diagrammed position, he apparently tired of passive defence, and lashed out with 30...Rxa5? (30...Ke7 is probably better), which after 31.bxa5 Rxa5 32.f4! Bxf4 33.Rg6 Kf7 34.Rxe6 Kxe6 35.Bxf4 left him with just two weak pawns for a bishop. Adams resigned on move 40.
