Italian Game Sacrifice Puzzle (Rated 1117): Back Rank Mate — Mate in 3

This middlegame puzzle shows how a seemingly active queen and rook can create a forced mating net against an exposed king. The key idea is to use a forcing sacrifice to drag the king into a vulnerable square, then exploit the lack of luft and the overloaded defenders around the back rank. Even when material is uneven, tactical threats can override static evaluation and turn a winning attack into a direct mate in 3.
