Priit Mihkelson is a black belt from Estonia who trained under SBG found Matt Thornton, and a member of the Brazilian Jiu Jitsu Globetrotters. I just found out about him last week when a friend that I train with sent me one of his videos. Since then I’ve traveled down the rabbit hole with Mihkelson’s material. His approach to jiu jitsu is very scientific, and from the videos I’ve seen he challenges some of the conventions that we’ve come to know in jiu jitsu.
The video below is a perfect example of challenging conventions. The guard break that he shows is essentially a stack pass. He says that we should sit in guard with “active toes” rather than flat feet (I think he’s calling flat feet “seal feet” in the video). His contention is that we should be on our toes, and pressuring down towards our partner so that we can react to things better. He’s not against posturing back, or standing up, but says we should also explore posturing into our opponent when we’re stuck in closed guard.
I’ve tried this pass a couple of times at class this week, I was able to put some pressure on my partners that they weren’t expecting, but I couldn’t quite get the legs to open to pass the closed guard. I’ve since re-watched this video and noticed that I didn’t have the correct angle. I took better notes, and will give this a try in the next class.
He’s also got a few videos for sale at BJJ Fanatics, which I’m looking forward to getting as some point. This one in particular I’m interested in:

While training at the Rickson Gracie Academy he worked as a secretary, instructor and even as a training partner for Gracie to help him prepare for his fights in Japan. He earned his black belt in 2004 and was the main instructor at Rickson’s place until a back injury forced him to stop.
