Vienna Game Advanced Pawn Intermediate Puzzle (Rated 1457): Checkmate with Bishop and Knight — Mate in 2

This middlegame puzzle shows how a passed advanced pawn can open the king’s shelter and create a forcing mating net. White’s attack is built around king safety, not material: the pawn on the seventh rank becomes a direct tactical lever, and the bishop joins the attack with a decisive diagonal. In classical chess, these patterns often appear when the defender’s pieces are overloaded and the king has too few flight squares. The result is a clean checkmate with bishop and knight coordination.
