Dutch Defense Sacrifice Intermediate Puzzle (Rated 857): Back Rank Mate — Mate in 3

This middlegame puzzle shows how king safety can outweigh material. White’s queen and rook coordination creates a forcing attack against the exposed king, while the defender is overloaded and the back rank is vulnerable. The key idea is a tactical refutation: a sacrifice opens lines, drags the king into a worse square, and sets up a mating net. In classical chess, these patterns often appear when active pieces target weak pawn shields and loose defenders.
