What are the main differences between Gracie Barra jj and just Gracie or Brazilian jj? I know GB was founded by Carlson and it's covered some in other threads like the Rickson FAQ, but I would like some clarification. If you train at a GB school, are you ranked in GB jiu jitsu or are you ranked in Brazilain jiu jitsu (that may be a stupid question) Are the differences really just tournament rules? Or are the fundamentals of the art different? Can non GB students participate in IBJJF tourneys? And just what are all the rule differences? Are the differences between the 2 styles just semantic or are there very distinct differences? What are some of the best non-GB camps? It seems to be popular opinion that GB schools are very high caliber compared to others. (This might be a misconception on my part) Thanks.
