Ruy Lopez Berlin Defense Exposed King Puzzle (Rated 1423): Mate in 3 — King Safety

This middlegame puzzle is a classic king-safety lesson: one exposed king, a loose kingside pawn shield, and a powerful queen and bishop battery aimed at the dark squares. The key idea is to use forcing checks to keep the defender’s king from escaping while the attacking pieces take control of the mating net. When the enemy king has few safe squares, a direct sacrifice or capture can open the final route to checkmate.
