I think a black belt should have mastered the general technique of their art, should be prepared to teach their art to students on any level, and should have developed their own feel and style for their art.
About the feel and style thing, you see bjj black belts that might pass the guard using "wrong" technique such as keep their head down and neglecting posture or leaving one arm behind, but they have just developed their own style and it's not as if someone is going to collar choke them or put them in a triangle when they are doing this. |
