Learn How to Spot Mate in 1: Endgame Checkmate
This chess endgame puzzle is a pure mate in 1, where the winning idea is to use the rook’s power on the seventh rank to deliver immediate checkmate. The key tactical motif is a mating net: the enemy king is boxed in by its own pieces and pawns, so a single rook move ends the game. In classical chess, these patterns often appear when lines are open and the king has no safe flight squares.
