Learn How to Win a Pin: Decisive Material Gain
This middlegame puzzle is built around a long-range pin that turns a seemingly active piece into a tactical liability. The key idea is to exploit alignment: when a defender is pinned to a more valuable target, forcing exchanges can win material or break the position open. Here, the attacking side uses piece activity, pressure on the center, and a vulnerable queen-side structure to create a sequence where the pinned piece cannot move freely without consequences.
