Zukertort Opening Mate In 2 Puzzle (Rated 871): Back Rank Mate — Chess Endgame Tactic

This chess endgame puzzle shows a classic back rank mate pattern: the enemy king is boxed in by its own pieces, and a rook can exploit the only open line to deliver a mating blow. Even though the material is balanced, piece activity and king safety decide the game. The key idea is to create a forcing check that leaves the king with no escape squares and no way to block the rook’s file.
