Sacrifice Puzzle (Rated 1281): Mate in 3 — Back Rank Mate

This puzzle is a classic middlegame mating net where the attacking side uses forcing checks to drag the enemy king onto a vulnerable square. The key idea is a back rank mate pattern supported by a queen sacrifice, with the rook delivering the final blow. Even though the material balance is heavily against White, king safety and piece coordination matter more than raw count here. In classical chess, these tactical shots often decide games instantly.
