Rook Endgame Puzzle (Rated 1567): Win a Rook Endgame — Crushing Defensive Move

This chess endgame is a classic example of using a forcing defensive move to turn active rook pressure into a winning tactical sequence. Even with material appearing balanced, the side with the more active king and rook can create decisive threats by attacking a loose piece and forcing the enemy king into a vulnerable square. In classical chess, these positions often hinge on open files, king activity, and whether a defender can be removed at the right moment.
