Owen Defense Mate In 1 Puzzle (Rated 1158): Spot a Mate in 1 — Classic Queen Trap

This middlegame puzzle is a pure tactical finish: White’s pieces are already aimed at the enemy king, and the position collapses because the king has no safe flight squares. The key idea is to recognize a mating net where the queen and bishop coordinate to seal the escape route. Even though material may be down, king safety overrides everything when the opponent’s back rank and pawn shield are weakened.
