Bird Opening Dutch Variation Sacrifice Intermediate Puzzle (Rated 1069): Spot Back Rank Mate — Mate in 3

This chess endgame puzzle shows a classic mating net built around the back rank. White’s king is short on luft, and the open f-file gives Black’s heavy pieces direct access to the king. Even though the position looks like a normal middlegame, the tactical reality is much sharper: the queen and rook coordinate to force the king into a corner and remove its escape squares. The key idea is not material, but forcing checks that leave the defender helpless.
