Learn How to Spot Mate in 1: Queen's Gambit Declined
This puzzle is a classic middlegame mate in 1 from the Queen's Gambit Declined, where king safety outweighs material and development. The key idea is to notice when the enemy king is boxed in by its own pieces and pawns, leaving a single forcing move that ends the game immediately. Even in a position with active pieces and extra material, a direct mating net can override everything else. Always scan for checks first when the king is exposed.
