The only decisive game of the fifth round was between former World Chess Champion Rustam Kasimdzhanov and Leinier Dominguez. The Bogo Indian was an interesting position with the Carlsbad pawn structure, and the resulting double Rooks endgame seemed headed for a draw. “Of course, with correct play it should be a draw,” Dominguez explained. However, he found 28…Kf8, which was a clever way to eliminate the problems with the 7th rank.

If 29.Rd7 black checks twice and picks the b2-pawn, at the same time protecting the b7-pawn. After 30…a5 the point is that every possible pawn endgame is winning for black. Kasimdzhanov’s King was cut on the back rank and he tried to dig in with his Rook on the third rank (g3). That’s why 33.e4 was played, but the precise 33…Re2 put white into zugzwang.
