Learn How to Spot Mate in 2: Endgame Pin
This chess endgame shows how a seemingly equal rook ending can hide a forced tactical finish. White’s pieces are active, the files are open, and the black king is boxed in by its own back-rank pieces. The key idea is to use a forcing check that creates a pin and removes the defender of the mating square. In classical chess, these short combinations often come from piece activity rather than material advantage.
