Learn How to Spot Mate in 1: Philidor Defense
This middlegame puzzle comes from the Philidor Defense and shows how quickly a kingside attack can become decisive when the enemy king is under pressure. White’s queen and bishop coordinate on the dark squares, while Black’s weakened pawn shield leaves the king vulnerable to a direct tactical finish. The key lesson is that active pieces near the king often outweigh material, especially when one defender is overloaded or a key square is left unprotected.
