Sacrifice Puzzle (Rated 1185): Mate in 3 — Back Rank Mate

This chess endgame puzzle is a classic example of a back rank mate built around king safety and forcing moves. White’s heavy pieces coordinate to restrict the enemy king’s escape squares, while a sacrifice removes the last defender and opens the mating line. Even though the position looks like a normal middlegame transition, the tactical reality is that the king is already boxed in. In classical chess, these patterns often decide games instantly when one side has an exposed king and overloaded defenders.
