Learn How to Spot Mate in 1: French Defense Exchange
This French Defense Exchange Variation puzzle is a classic middlegame tactical finish where the position collapses because the king’s protection is overloaded and a key piece is left hanging. White’s active rook and bishop work together to exploit the open e-file, the pinned f-pawn, and the exposed back rank. Even though the material looks close, the king safety imbalance is overwhelming, so the correct move ends the game immediately with a direct mating pattern.
