Ruy Lopez Cozio Defense Beginner Puzzle (Rated 1477): Win Material — Crushing Opening Tactic

This Ruy Lopez middlegame shows how a seemingly safe kingside setup can hide a tactical collapse. White’s pieces are coordinated around the enemy king, and the key idea is to exploit a pinned pawn and a loose defender on the kingside. In classical chess, these positions often reward forcing moves that remove the defender and open lines against the king, even when material is already imbalanced.
