Just awesome to watch. Quite simply, one of the best BJJ performances I have ever seen. I was so lucky to see it live and up close. Just essential BJJ done at the highest level. Nothing fancy. Someone with less than two years of training will know every technique here. But this is how it is done with ultimate timing, position, and control.
This is how it is done, whether the context is sport grappling, MMA, or self-defense.
