Learn How to Win With a Fork: Endgame Pin
This chess endgame puzzle shows how a seemingly active rook can become vulnerable when a pinned piece and a loose back-rank-style king setup combine. The key idea is to use a forcing tactical sequence that wins material by creating a fork and exploiting a long pin on the enemy rook. In classical chess, these patterns often appear after simplification, when piece coordination matters more than king safety and one tactical shot can decide the game.
