I really have to know this so i would appreciate the replys.
I know a punch to the jaw can possibly ko your opponent.

My question is
excactly what part of the jaw must be struck and what angle must it be struck at to break someones jaw
and what part of the jaw can be hit to just ko him.
I dont want to break anyones jaw cause of the law suit, but a ko would be needed.
So excactly what part must be hit to break it?
