Ruy Lopez Berlin Defense Exposed King Puzzle (Rated 1178): Mate in 3 — Exposed King

This middlegame puzzle is a classic exposed-king attack: White’s pieces are coordinated around the enemy king, and the position is ripe for a forcing tactical finish. The key idea is to use checks that restrict the king’s escape squares while the queen and knight work together to create a mating net. Even though material is not in White’s favor, king safety is the dominant factor, and that often outweighs countable material in classical chess.
