Ruy Lopez Opera Mate Beginner Puzzle (Rated 887): Spot Opera Mate — Mate in 1

This middlegame puzzle is a classic example of an opera mate style finish: the attacking side uses active rooks and a vulnerable king to force immediate checkmate. The key idea is that the defending king has limited escape squares, while the heavy piece invasion creates a mating net on the back rank and along open files. In classical chess, these patterns often appear when king safety matters more than material.
