Learn How to Win Material: Pin Tactics
This Ruy Lopez middlegame puzzle centers on a classic pin-based tactical idea: one active piece is tied to the king, and that restriction creates a winning sequence. White’s rook lift to the open file increases pressure on the enemy queen and the pinned knight, turning a static weakness into a concrete tactical target. In positions like this, the best move is often a quiet improving move that makes the pin more powerful and forces the opponent into a defensive concession.
