Learn How to Exploit a Pin: Decisive Material Gain
This middlegame puzzle is all about using a pin to create a decisive material gain. White’s active bishop pressure on the enemy queen and king line turns a seemingly normal position into a tactical problem, because the queen cannot move freely without dropping important material. The key idea is that the pinned piece becomes overloaded: if it captures, it can be recaptured by a rook and the position collapses into a winning simplification for White.
