Deflection Puzzle (Rated 1117): Mate in 3 — Back Rank Mate

This chess endgame puzzle is a classic example of a back rank mate pattern where the enemy king is boxed in by its own pieces and pawns. Even though White is materially ahead, the win comes from forcing the black king into a mating net rather than winning more material. The key idea is to use checks to restrict the king’s escape squares and create a decisive tactical sequence. In classical chess, these patterns often appear when rooks and minor pieces coordinate against a cramped king.
