Ruy Lopez Schliemann Defense Kingside Attack Puzzle (Rated 973): Spot Mate in 1 — Kingside Attack

This middlegame puzzle is a classic king-safety finish: one side’s queen is already aimed at the enemy king’s shelter, and the final blow comes from a direct mating net. The key idea is that active pieces can work together to exploit weak dark squares, pinned pawns, and an exposed king. In classical chess, these patterns often appear when the defender’s king has few escape squares and the attacking queen can deliver a forcing check on the g-file or near the king’s pawn shield.
