Learn How to Spot Mate in 1: King Safety
This puzzle is a classic example of a forcing mate in one, where king safety matters more than material. In the middlegame, the defending king is boxed in by its own pieces and pawns, leaving a single checking move that ends the game immediately. Even though the position may look materially balanced or even better for one side, tactical threats can override everything when the king has no escape squares and no adequate blocks or captures.
