Learn How to Spot a Mate in 1: French Defense
This middlegame puzzle comes from the French Defense and shows how a kingside attack can end the game instantly when the enemy king’s shelter is weakened. Black’s queen and bishop coordinate on the h-file and dark squares, creating a mating net around White’s king. The key lesson is that tactical pressure is not always about winning material; sometimes the most forcing move is the one that ends the game immediately with checkmate.
