Sacrifice Puzzle (Rated 1098): Spot a Mate in 3 — Back Rank Mate

This classical chess puzzle is a great example of how king safety can outweigh material. In the middlegame, the defending king is boxed in by its own pieces and pawns, creating a mating net on the back rank. The attacking side uses forcing checks and tactical coordination to overload the defense. Even when one side appears materially better, a hidden mate in 3 can flip the evaluation instantly.
