I'm fresh from a full-contact sparring session with one of my mates from work, and i've foind something quite useful. He started attacking quite hard and fast, and got me off balance n threw a cross, but, in my off balanced state i threw a half palm-heel half knife hand to his temple n turned my head to take his cross on the side of my jaw (instead of a bare knuckle punch to my mouthgaurd, which bloody well hurts)... we hit each other at the same time, but this open handed strike of mine, which hit with the heel of the hand, was enough to make my mate see stars. All it was was the kind of movement one would make if slamming a door shut, and it was purely instinctual. I suggest anyone looking for the power of a hook with a bit more distance try this shot. I know Bas Rutten used to use it a lot in his Pancrase tournaments to good effect (they were only allowed to use open hands anyway). Just a thought on a new technique peoples. fskarateoz
