Endgame Study #24: Bishop and Queen Power

Hey all! Welcome back to my 24th blog post regarding endgame studies! Reminder: tomorrow is a prize problem, meaning that the first 5 people to post "solved" will get an award! Enjoy the puzzle!

Scroll down for small and big hints...

Small hint: Use elimination - black's king cannot go to certain squares because of a double attack from the bishop.

Big hint: Try to use both your bishop and queen together to checkmate/win the queen! You don't have to keep checking non-stop to do this!
