checkmate with king+knight+bishop

It takes 20 something moves to checkmate a king with bishop, knight and king. I dont even know how to do it. Mrwizard my coach was in a tournement and he had a bishop king and knight vs a king. he had 1 hour so he read a book and found out how to do it. I thought it was cheating. So anyone here know how to do it?

I think it's pretty hard (haven't done it yet), but here is a video you can watch on how to.

yeah I do

um... I'm not too sure about the "reading a chess book during a tournament game" incident. Thats seems like cheating to me too. As for the mate... I will learn it... sooner or later, but I ever see it before than I know the basic plan:

a.) herd opponent's king to side of board.

b.) herd king to a corner the same color as your bishop. (this is hard, there is ppoint where you have to let the king come off the side of the board) 

c.) once he's near the corner it just takes calculation.

here's a small tutorial for KNB that I wrote when I was learning it myself:

KNB is hard only before you have studied & drilled it. after a while it gets ridiculously easy, and the speed you can move the mouse becomes the limiting factor. anybody can learn it with a little work, and although you're not gonna face it almost ever, you'll reap huge benefits for increased board vision & sense of piece coordination.

he didn't he read it in breaktime in a match

pinapple y do u make so much fourms about ur coach

The golden key to this awesome endgame is this... Don't waste time on an endgame that is rarely seen in practice, and even more rarely concluded correctly!!! Spend your time on something useful so you can take the kings head before such a troublesome ending comes about ; )
