Scandinavian Defense Mieses Kotroc Variation Puzzle (Rated 842): Royal Fork — Win a Queen

A royal fork is a double attack against the enemy king and queen — the most devastating single move in chess, because the king must always be answered first. When a bishop lands on a square that both gives check and eyes the queen, the defender is forced to deal with the check, and the queen falls. Here White's king is exposed on c1 while the queen pushes deep to h6; one bishop move hits both targets on the same diagonal and flips a losing material score into a decisive win.
