B.J. Penn brought out the cameras to show people a little of what goes on in one of his classes. The snippet he showed at bjpenn.com was something he called “jiu jitsu 101.” It is a sort of lock flow that has students move from mount escape to guard open to combat base to guard pass to side control.
Code for the flow would be something like: “mount escape” to Buddha to Jayhawk to Master to Watch Dog.
