Learn How to Use a Pin: Winning Material
This middlegame puzzle is built around a powerful pin that turns a defended piece into a tactical target. When a lower-value piece attacks a more valuable one, the pinned defender can’t move without exposing the king or another major piece. That restriction often creates a winning combination, especially when the pinned piece is also overloaded. In practical chess, pins are one of the cleanest ways to convert a small edge into decisive material gain.
