One Queen Move, Two Targets
Black's bishop sits undefended on the same rank the queen can reach.
Your Move
White to move. Find the single queen move that wins the bishop.
Solution: 1. Qh5+
Qh5+ checks the king along the h5–e8 diagonal and simultaneously attacks the undefended bishop on a5 along the open 5th rank — safely, since a bishop can never move along a rank to capture back. Black must answer the check, and the bishop falls next.
