Learn How to Exploit a Pin: Ruy Lopez Tactics
This puzzle comes from a Ruy Lopez Berlin Defense middlegame where king safety is the main imbalance. White’s rook activity on the e-file creates a powerful pin against the black queen and king, turning a seemingly active queen into a tactical liability. The position is a classic example of how a short forcing sequence can punish an exposed king and an overloaded defender. Even though Black has extra material, the coordination of White’s pieces makes the position tactically unstable.
