In this position from a game Krasenkow - Karpow Karpow moved 29… Re1! .
The white rook on f1 now has to protect the pawn on f3 (there is a threat of Qxf3 # ), but at the same time shield the king from the black rook on e1 . The white tower is hopelessly overwhelmed with this double task. Logically, Krasenkow gave up the game at this point.
