Learn How to Exploit a Pin: Winning Material
This middlegame puzzle is built around a forcing pin that turns a defended-looking position into a winning material sequence. The key idea is that one piece is tied to the king, so a tactical jump can create a direct check and overload the defense. Once the king is forced to respond, the pinned line collapses and a valuable piece becomes vulnerable. In classical chess, these moments often decide the game because activity and king safety outweigh static material balance.
