Duras Gambit Fork Beginner Puzzle (Rated 1272): Mate in 3 — Bishop Fork

This middlegame puzzle shows how a forcing bishop check can start a mating net when the enemy king is stuck in the center and short on defenders. The key idea is deflection: the first check drags the king onto a worse square, opening lines for the queen to invade. Even though Black is materially ahead, active piece coordination and king safety matter more than raw material when the attack is immediate and precise.
