Learn How to Pin: Endgame Mate in 1
This puzzle shows how a pin can turn a seemingly ordinary endgame into a forced finish. White’s attacking pieces coordinate against the black king, and the key defender is restricted by the alignment of king and pawn. In classical chess, these tactical motifs often appear when the king is exposed and the opponent’s pieces are overloaded. The position is a great example of how a single active rook can convert pressure into immediate mate.
