Learn How to Exploit a Pin: Winning Material
This middlegame puzzle comes from the Queen's Gambit Declined and highlights how a pin can create a decisive tactical edge. White’s pieces are active, while Black’s king is exposed in the center and several black pieces are tied down. The key idea is that a forcing check can drag the king into a worse square, allowing White to win material by attacking overloaded defenders and loose pieces. It is a classic example of using activity and coordination to convert a tactical opening into a concrete advantage.
