Botez Gambit Puzzle (Rated 860): Back Rank Mate — Mate in 3

This chess puzzle is a classic mating net built around king safety and a vulnerable back rank. White’s queen and rook coordinate to exploit the exposed black king, while the opponent’s active pieces are overloaded and unable to defend every threat. The key idea is a forcing sacrifice that drags the defending rook away from its ideal square, opening a direct line to mate. In practical classical chess, these patterns often appear when one side’s heavy pieces are active and the king has limited escape squares.
