Learn How to Exploit a Pin: Tactical Refutation
This middlegame puzzle comes from the Italian Game and shows how a pinned piece can become the target of a forcing tactical refutation. White’s active pieces and king safety issues create tension, but Black’s best response is to use the pin on the queen and knight to win material. The key idea is that a seemingly strong attacking piece can be overloaded when it is both attacked and tied to a more valuable target.
