Sicilian Defense Closed Mate In 3 Puzzle (Rated 1178): Spot Mate in 3 — Back Rank Mate
This middlegame puzzle is a classic example of a back rank mate pattern combined with deflection and a forcing tactical sequence. White’s heavy pieces coordinate against the king’s shelter, and the key idea is to lure a defender away so the final mating net becomes unavoidable. The position also shows how a seemingly active queen can create a decisive attack when the enemy king has limited luft and the back rank is vulnerable.
