Learn How to Clear the Pin: Decisive Material Gain
This middlegame puzzle is built around a clearance idea: one piece is removed to open lines and expose a tactical weakness. The key feature is a long-range pin that makes a seemingly active defender vulnerable once the position is opened. After the first tactical shot, the follow-up relies on forcing exchanges and improving piece coordination, turning activity into a concrete material win. It is a classic example of how tactical refutation can override static material balance.
