Botez Gambit Puzzle (Rated 966): Spot Back Rank Mate — Mate in 3
This chess endgame-style middlegame puzzle is a classic example of a back rank mate pattern. White’s king is boxed in by its own pieces and pawns, while Black’s heavy pieces coordinate to exploit the weak back rank and the exposed f-file. The key idea is not just checking the king, but forcing it into a narrow corridor where every escape square is controlled. Once the defender is overloaded, a sacrifice can clear the way for a decisive mating net.
