Ruy Lopez Open Berlin Defense Puzzle (Rated 966): Win Material — Ruy Lopez Tactic

This middlegame puzzle shows a classic Ruy Lopez idea: use active pieces to exploit loose coordination and win material with a forcing tactical refutation. White’s queen and rook work together against the black queen-side structure, and the key is that the black queen is overextended while the king remains stuck in the center. The position rewards sharp calculation, but the underlying concept is simple: when a major piece is attacked and a tactical line opens, the best move can convert pressure into a decisive material gain.
