Learn How to Spot Mate in 1: Discovered Check
This puzzle is a classic middlegame mating pattern where a single forcing move ends the game immediately. The key idea is a discovered check that also creates a double-check, leaving the defending king with no legal escape. In practical classical chess, these motifs often appear when pieces are aligned on open files and diagonals, and the opponent’s king has weakened shelter. Always scan for forcing moves first, especially when a piece can move with tempo and reveal another attacker.
