Mate In 1 Puzzle (Rated 1152): Spot Mate in 1 — Middlegame Tactic

This puzzle is a classic middlegame mating net where king safety outweighs material. Even though one side may be down in material, the exposed king and loose pieces create a forcing finish. The key idea is to look for checks first, then ask whether the king has any legal escape squares, captures, or blocks. When those are all removed, a single tactical move can end the game immediately.
