Learn How to Spot Mate in 1: French Defense
This middlegame puzzle shows a classic king-safety collapse in the French Defense. White’s queen and rook coordination creates a direct mating net against the black king, with the key idea being that the defender’s pieces and pawn shield are too overloaded to respond. In classical chess, these positions often come from active queen placement, open lines, and a vulnerable king that has lost its shelter. The tactical finish is immediate because the mating square is protected and the king has no flight squares.
