Learn How to Spot Mate in 1: French Defense
This French Defense Advance Variation puzzle is a classic middlegame example of king safety deciding the game. White’s queen and bishop coordinate to overload the dark squares around the black king, while Black’s pieces are too tied up to help. The key idea is that when the enemy king is exposed and the back rank or escape squares are restricted, a single forcing move can end the game immediately. Look for direct checks, pinned defenders, and squares that cannot be covered in time.
