Back Rank Mate Beginner Puzzle (Rated 978): Back Rank Mate — Mate in 3

This middlegame puzzle shows a classic back rank mate pattern where the defending king is boxed in by its own pieces and pawns. The key idea is that the attacking side uses a forcing check to drag the king onto a vulnerable square, then exploits the lack of luft and the overloaded defender. Even though material is heavily in White’s favor, the real finish comes from a precise mating net rather than simple simplification.
