Mate In 2 Puzzle (Rated 1371): Spot Mate in 2 — Rook Endgame

This chess endgame puzzle is a classic example of how active rooks can create a mating net even with equal material. The key idea is to use forcing checks to drive the enemy king onto a vulnerable square, where the rook can deliver a decisive finish. In rook endgames, king activity matters, but so does coordination: one active rook can dominate files, cut off escape squares, and turn a seemingly balanced position into a forced mate.
