Learn How to Win with a Pin: Middlegame Tactics
This middlegame puzzle is built around a powerful pin that ties a key defender to the king and turns a seemingly active position into a tactical collapse. The attacking side uses pressure on open lines, forcing moves, and king safety to create a decisive sequence. Even when material is close, a pinned piece can become overloaded, trapped, or unable to defend critical squares. That is why classical chess calculation often rewards activity over raw material.
