Mate In 1 Intermediate Puzzle (Rated 804): Mate in 1 — Chess Endgame Tactic

This chess endgame puzzle is a classic mate in 1: the attacking side has a direct checkmate available because the enemy king is boxed in by its own pieces and pawns. In positions like this, the best move is often a forcing rook or bishop move that seals every escape square at once. Even when material is down, a mating net can override everything else. The key is to look for immediate checks before considering any quiet improvement.
