If kids say they can't breath, my opinion is they are saying that because they are about to get pinned....if you can talk, you can breath. I referee and unless they are bleading or it is potentially dangerous I won't stop the match. As for 4 points, its actually however many near fall points earned plus one. So if a ref only has a 3 count, then the top wrestler only gets 3 pts. But if he has reached a 5 count then 4 pts are awarded.
