Team CKD competes in the National Blackbelt League (NBL). The NBL is the only international sport karate league based upon a series of open tournaments which rate and qualify blackbelt level players to become official sport karate world champions at a year-end championship called the “Super Grands World Games”.

The Super Grands and most NBL sanctioned tournaments follow the Sport Karate International Tournament Alliance (SKITA) Rules. For a copy of the SKITA Rulebook and more information on the NBL, please visit them at www.nblskil.com.
