White to play and win in 3. I've been looking at this for days and getting nowhere!

Go to: https://www.chess.com/analysis

Click "Load FEN" and paste "8/6Kn/1Q4B1/3pk3/8/8/5P2/8 w - - 0 1"

It will then show you various different lines one of which is a mate in 3. 

If you only want a hint the first move is to do with the queen.

Qc6 <--- highlight here for the move if you are still stuck

Thank-you. Took me a little while to get to grips with the analysis tool but much longer to convince myself it was truly a force win no matter what black did. A very clever puzzle. Cleverer than me, anyway.
