Opera Mate Intermediate Puzzle (Rated 943): Spot Mate in 2 — Back Rank Mate

This chess puzzle is a classic mating net built around king safety and rook coordination in the middlegame. White’s heavy pieces are already active near the enemy king, and the position shows how a trapped king can be finished with a forcing check. The key idea is that one checking move can restrict the king’s flight squares so completely that the follow-up becomes unavoidable. Patterns like this often appear in classical chess and opera mate style combinations.
