Ruy Lopez Cozio Defense Beginner Puzzle (Rated 1385): Win Material — Tactical Refutation
This middlegame puzzle is a classic tactical refutation: one side has active pieces, but the position contains an overloaded defender and a hanging piece. The key idea is to force simplification in a way that wins material and leaves the opponent unable to keep everything protected. In practical classical chess, these moments often decide the game immediately because the best defense is tied to multiple duties at once.
