Learn How to Spot Mate in 1: Pin Tactic
This chess puzzle is a classic middlegame tactic where the king is vulnerable and one forcing move ends the game immediately. The key idea is a pin: a piece is immobilized because moving it would expose the king. In positions like this, strong attackers often combine piece activity, king safety, and direct threats to create a mating net. Even when material is down, a single forcing move can override everything else and decide the game at once.
