Sacrifice Puzzle (Rated 1473): Win with Opera Mate — Mate in 3

This puzzle is a classic kingside attack where White uses a forcing sacrifice to drag the black king into a mating net. The key idea is not material gain but coordination: the queen, rook, and bishop work together to exploit the exposed king and weak pawn cover. In classical chess, these tactical shots often appear when a defender is pinned or overloaded and the king has too few escape squares.
