Botez Gambit Puzzle (Rated 958): Spot Back Rank Mate — Mate in 3

This chess endgame puzzle is a classic forcing sequence built around king safety and a vulnerable back rank. White’s queen is active deep in the position, and Black’s king has limited escape squares because the pawn shield is weakened. The key idea is to use checks that force the king into a tighter box, then coordinate the queen and rook to finish the attack. In classical chess, these mating nets often appear when one side’s pieces are overloaded and the king has no luft.
