Sacrifice Puzzle (Rated 1303): Spot Mate in 3 — Back Rank Mate

This puzzle is a classic middlegame tactical finish built around king safety and a back rank mate pattern. White’s pieces are active, but the real story is the exposed black king and the limited escape squares around it. The key idea is to use forcing checks to drag the king into a mating net, then coordinate the queen and rook for a decisive finish. In classical chess, these motifs often appear when one side has a loose back rank and overloaded defenders.
