Learn How to Back Rank Mate: Endgame Tactic
This chess endgame puzzle shows how a seemingly active rook can become a tactical liability when the enemy king has limited flight squares. The key idea is a forcing sequence that uses check to drag a defender onto a critical file, then exploits the pinned or overloaded piece to finish the attack. Even in classical chess, simple-looking positions can hide a mate in 3 when the back rank is weak and the king has no escape route.
