Opera Mate Intermediate Puzzle (Rated 933): Mate in 2 — Back Rank Mate

This chess endgame puzzle is a classic mating net where the attacking rook coordinates with the king’s limited escape squares. The key idea is to use a forcing check that drives the enemy king onto a vulnerable square, then finish with a second rook move that seals every flight square. In classical chess, these patterns often appear when the opponent’s pieces and pawns accidentally box in their own king, creating a sudden mate in 2.
