Rook Endgame Puzzle (Rated 1461): Win a Chess Endgame — Rook Trap

In classical chess, rook activity matters, but activity without safety can backfire fast. Here, the key idea is to use forcing play to win material and then convert with king activity and pawn play. The position is a clean example of a tactical refutation inside a rook endgame, where precise calculation matters more than general plans.
