Recently, I went up to Nashville for a Sambo seminar put on by this guy:
He displayed many evil evil things to do to BJJ people who are not accustomed to leg locks.
But the thing I think I will remember most is Basket Brawl. He prefaced the game with a warning of bruises and black eyes. Of course, I was inherently hesitant to even play. But once we started playing I did not want to stop.
One of the episodes of Human Weapon talked about it.
We did not have enough room to remain standing during the game so we stayed on our knees. Only the leg locks were out of bounds.
It is definitely a warm up that I was not use to.
