In game one of round five, every game ended in a win for white. Top seeds Topalov (who had won every game apart from one draw going into this round) and Adams won as expected, but the other two wins were slight upsets. Radjabov lost to Dominguez after a complicated opening after which white emerged with three connected passed pawns for a bishop, and Grischuk lost to Kasimdzhanov in an exchange Ruy Lopez. In the position shown in the diagram, which appears to be better for Black, Grischuk slipped up with 46. ... Bc2? allowing 47. Ne6+. This forks the king and bishop on c5, so 47. ... Rxe6 is forced, but this deflects the rook from defence of d7, allowing 48. R3d7+ Kb6 49. Rb8+, a skewer which picks up the rook on b2. Grischuk fought on before resigning on move 73. The match Radjabov-Dominguez ended 3½–3½ with Radjabov only advancing by virtue of drawing with black in the final Armageddon tie-breaker.
