Sacrifice Puzzle (Rated 1211): Spot Back Rank Mate — Mate in 3

This chess endgame puzzle is a classic example of a back rank mate pattern hidden inside a tactical sequence. White’s heavy pieces coordinate to exploit the enemy king’s limited escape squares, while a bishop sacrifice clears the way for a decisive rook-and-queen finish. Even though the position looks materially balanced enough to defend, the real story is king safety: once the defender is deflected, the back rank becomes fatal. In classical chess, these mating nets often appear after forcing checks and sacrifices.
