Clever Ending

This is taken from the latest Australasian Chess magazine. A neat little problem that contains plenty of instructive value.

that's brilliant

a brilliant study! - so rare on this site now...

Very clever indeed my friend thank you!

I just managed to solve. But basic idea were clear. Sac of bishop almost forced. So you must look how to save rook.And rook chech became clear, now if one can exchange rooks then lone knight is harmless. I hoped black king will go to f7 but  it went to h7. Now Kb3 looks more natural but then black ends of with a rook instead of knight. So look for stalement then Kb1 seems much better.
