Vienna Game Mate In 1 Intermediate Puzzle (Rated 1100): Mate in 1 — Bishop Checkmate

This puzzle is a clean middlegame mate in 1, where White’s pieces coordinate to exploit the exposed black king in the center. The key idea is a bishop checkmate pattern: the bishop lands on a square that attacks the king directly while also controlling the king’s escape routes. In positions like this, king safety matters more than material count, and a single forcing move can end the game immediately.
