I remember reading somewhere that Enho has great difficulties gaining weight. He literally eats himself nauseous, but still can not gain weight. He is now down on 92 kg. I think he weighed in on 99 a couple of tournaments ago. The fighters now all know that he has no defence against a careful straight push out. He is just to light weight. As long as they don't let him slip in under them or to the side of them, there is precious little he can do to defend against a cautious push out attack.
I wish I shared Enho's weight gaining problem
