Stupid question, I'm sure: I just got back into BJJ after a 7 year lay-off and I keep hearing of this event/organization so obviously, it's important. It was probably around when I used to train, but I've never heard of it until now. I searched here and found little to answer my questions. Is ADCC the same as Abu Dhabi (Joe Rogan talks about it in UFC's)? Is it an event, org, or both? Is it American, Brazilian, or Middle Eastern, as the name implies? I also know that some world-class grapplers compete in it, and there are videos available. Where can I find these? Any links would be helpful. Thanks.
