Sacrifice Puzzle (Rated 800): Spot Mate in 3 — Back Rank Mate

This middlegame puzzle is a classic example of a back rank mate pattern hidden inside a tactical sequence. White’s pieces are coordinated to exploit the enemy king’s limited escape squares, while the heavy pieces create a mating net around the back rank. The key idea is that a forcing queen sacrifice can drag the defender away and overload the remaining rook, turning material imbalance into a direct attack. In classical chess, these motifs often decide games instantly.
