It is mandatory for all the male black belts and female brown and black belts to carry the IBJJF/USBJJF/CBJJ membership id cards in the IBJJF sanctioned events. The schedule will be available February 23rd. Each academy can only have two athletes in the same division (of age/weight/belt). Depending on the number of athletes in the tournament, some classes may not have an absolute division. Before each fight, athletes will be asked to show their Ids to the officials. Make sure you have it at hand.
