Sacrifice Puzzle (Rated 1356): Spot a Mate in 2 — Back Rank Mate
This puzzle is a classic middlegame tactical finish where king safety matters more than material. White’s pieces are active, the black king is boxed in, and the queenside structure creates a vulnerable target. The key idea is a forcing queen sacrifice that drags the king onto a fatal square, allowing a rook to deliver the final blow. In classical chess, these patterns often appear when one side’s heavy pieces coordinate against a cramped king.
