Learn How to Spot a Mate in 1: French Defense
This French Defense puzzle is a classic middlegame mating pattern where White’s active pieces coordinate against the black king’s weakened shelter. The key idea is that the king’s defenders are overloaded and the final blow lands on a vulnerable square near the king. In positions like this, piece activity matters more than material count: a single forcing move can end the game immediately when the enemy king has no safe escape squares and the checking piece is protected.
