Learn How to Spot Mate in 1: King Safety
This middlegame puzzle is a classic example of king safety deciding the game immediately. White’s queen is already active near the enemy king, and the black king’s shelter is loose enough that one forcing move ends the struggle at once. In positions like this, the strongest tactic is often not material gain but a direct mating net. When the opponent’s king has limited escape squares, even a single well-placed queen move can be decisive.
