What are the rules (or ethical practice) around taking people qualified as black belts, and having them compete as a red belt? I know someone who is a black belt, and was shocked to see them competing last month as a red belt. This was both for Poomsae and sparring. He was competing as a red belt, under the direction from his Dojang master. I guess from one perspective, no big deal for Poomsae, as it is non-contact, and in theory every black belt should know their patterns. However the issue is with sparring, where a black belt, who knows more techniques and has moreexperience, and competing against a lower belt. That can't be fair, or ethical?
