Nimzowitsch Defense Smothered Mate Beginner Puzzle (Rated 1177): Spot a Smothered Mate — Mate in 1

This middlegame puzzle comes from the Nimzowitsch Defense and shows how a cramped king can be punished when its own pieces and pawns block escape squares. The key idea is a smothered mate pattern: the king is boxed in by its own army, so a single forcing move can end the game immediately. These positions often appear when one side has active knights and the opponent’s queen, rooks, or bishops are poorly coordinated.
