Exactly. Size means nothing. I have seen 5'2 guys take out 6'4 240lbs monsters before. If you want a quick ending, go for a straight shot to the jaw. There is a nerve behind the jaw and when it is struck, it IS lights out. For guys who are 8ft tall and 400lbs, it will still knock them out. If you hit them hard enough in the jaw, it will actually impact their brain giving them a concussion.

For a bloody battle, go for the bridge of the nose. That will cause their eyes to water up, blinding them, then that gives you a chance to really give it to them.
