Ah I was in one. If you ever see one of the competitor's knock down or knock the wind of his opponent, he is usually awarded half a point.. I cant remember if the judges award it or the ref.If it's the Judges like I think then they should raise a flag corresponding to either red or white depending on the one who knocked the opponent down. Its been awhile, and the ref was a Senpai. but thats the only way to receive a point.
