Learn How to Win with a Pin: Long Middlegame Tactics
This puzzle is a classic example of a long middlegame pin turning into a forcing tactical sequence. The key idea is that one piece is overloaded by king safety and material concerns, so a tactical shot can attract a defender onto a square where it becomes vulnerable. Once the defender is drawn away, the pinned piece and the exposed king can no longer coordinate. In classical chess, these positions often look messy, but the underlying pattern is simple: force, pin, and win material.
