Learn How to Exploit a Pin: Decisive Material Gain
This middlegame puzzle shows how a pin can turn a strong-looking piece into a liability. White’s bishop is active and advanced, but it becomes vulnerable once the rook takes control of the file and the king alignment matters. The key idea is that a pinned piece often cannot move because doing so would expose something more valuable behind it. In practical chess, these positions reward forcing moves, accurate calculation, and awareness of overloaded defenders.
