Zukertort Opening Sacrifice Puzzle (Rated 1154): Spot Back Rank Mate — Mate in 3
This puzzle is a classic back rank mate pattern in a sharp middlegame. White’s queen and rook coordinate to exploit the enemy king’s limited escape squares, while the h-file becomes the key attacking lane. The position also shows how a sacrifice can force the defender’s pieces into awkward squares, creating a mating net. Even with material down, the attack works because the king is boxed in and the final rook lift is decisive.
