The final position is not hard to see, but working out how to force it without the king having a chance for repeat position draw -- that's what makes this one quite tough. My short term memory isn't great but I could swear I managed to give him forced moves the whole way, ( which I didn't think would be possible) ... (incidentally making this puzzle quite valid , IMHO). May have to work this again later to be sure. Anyway, S p o i l e r A l e r t : This mate can only be delivered as a discovered check, and I needed to sac 2 bishops at a1 in the process. Did anyone's mileage vary on that last point?

When I first found out white can checkmate, I was stunned. But as a analyzed a bit, and watched a video, I noticed that 2 bishops can indeed be saced on a1. It's more of a pattern that'll guide you to a solution to checkmate in indeed, 9 moves.
