Bishops Opening Mate In 1 Puzzle (Rated 915): Spot Mate in 1 — Bishop's Opening Theory

This puzzle comes from the Bishop's Opening Vienna Hybrid and shows a classic mating pattern in the opening. White has a large material edge, but the real lesson is tactical: when the enemy king is still exposed and key defenders are overloaded or misplaced, a single forcing move can end the game immediately. In classical chess, these short tactical shots often appear when development is incomplete and the king lacks a safe shelter.
