Kiss Of Death Checkmate Puzzle (Rated 1500): Spot Mate in 1 — Kiss-of-Death Pattern

This puzzle is a classic kiss-of-death finish: the attacking queen lands on a square that the enemy king cannot escape from, while nearby defenders are overloaded or pinned. The position is built around king safety, with the white rook already controlling the open file and the black king boxed in by its own pieces. In classical chess, these are the moments where activity matters more than material, because one forcing move can end the game immediately.
