KNB vs K

I know the final mate looks something like this, but how do you force the king into its corner?

Thank you scherbak, I understand now how you have to block the king from escaping.  Will just have to practise!

The scariest mate to learn! I will put in the effort needed to learn this mate when I actually need to use it.

Just remember it must be a corner which is the same colour as your bishop.

I have no clue how to do this checkmate, and I've never had a position where I've needed to. 

Its pretty rare, I've been on the losing side of it a few times but never the winning 😐 All you need to do is zugzwang the king into a corner the same colour as the bishop. Max it takes is around 30 moves I think from the most awkward starting point.
