Learn How to Win a Rook Endgame: Crushing Pin
This chess endgame shows how active rooks can decide the game when one piece is pinned to a king. The key idea is that a seemingly safe defensive move can fail if the rook on the open file is overloaded or tactically tied to the king. In classical chess, rook activity often matters more than raw material, and here the stronger side uses that activity to force a winning simplification. Always check whether a pinned rook can be challenged or exchanged.
