Mate In 2 Puzzle (Rated 414): Spot Back Rank Mate — Rook Endgame

This chess endgame puzzle is a classic back rank mate pattern: the enemy king is boxed in by its own pawns, and a rook can exploit the lack of luft. In rook endgames, even a small tactical detail can decide the game instantly. Here, the key idea is to use forcing checks to overload the defender and create a mating net on the back rank. These positions reward calculation, not slow maneuvering.
