Ruy Lopez Steinitz Defense Kingside Attack Beginner Puzzle (Rated 911): Mate in 1 — Ruy Lopez Tactics

This middlegame puzzle comes from a Ruy Lopez structure where king safety outweighs material. White’s queen is aggressively placed near the enemy king, and the black kingside has loosened just enough for a direct finish. In classical chess, these positions reward alertness to forcing moves, especially when the opponent’s king has limited escape squares and nearby defenders are overloaded or pinned. The key idea is to recognize when a mating net is already complete.
