Opera Mate Puzzle (Rated 900): Spot Opera Mate — Chess Endgame Puzzle

In practical classical chess, these one-move finishes often appear when the enemy king is boxed in by its own pieces and pawns. Even in a seemingly quiet position, a single forcing move can turn king safety into the deciding factor and override material balance.
