Learn How to Spot Back Rank Mate: Mate in 3
This middlegame puzzle is a classic mating net built around king safety and piece coordination. White’s pieces are active, but Black’s king is vulnerable because the back rank is cramped and key defensive squares are overloaded. The tactical idea is to force the king into a narrow corridor, then use a queen and rook battery to finish the attack. Even when material is roughly balanced, direct threats against an exposed king can decide the game immediately.
