Learn How to Win with a Pin: Crushing Endgame Tactic
This puzzle shows how a pin can turn a seemingly active position into a tactical collapse. The key idea is that one piece is tied to the king, so its movement is restricted and the whole defensive setup becomes fragile. In this kind of middlegame-to-endgame transition, king safety matters more than material count alone. Once the pinned piece is overloaded, a forcing sequence can win material or create a decisive attack.
