Learn How to Exploit a Pin: Winning Material
This middlegame puzzle is built around a classic pin-based tactic. One side has active pieces aimed at the king, and the key defender is overloaded by pressure on the same file and diagonal. The position rewards accurate calculation because a seemingly natural defensive move fails to solve the underlying problem. Instead of chasing a direct attack, look for a forcing move that improves piece activity and turns the pin into a material win.
