I really like that knee bar from Brent. I prefer using the buttocks compressor to pass, but that looks like a good attack to have in my back pocket.
That rolling kimura to the back is sick! I'll be waiting a while to use it though.
Loving the prison guard attacks too. I need to start working more attacks from closed guard. I gotta work on being comfortable there. I usually fight to get on top and I'm sure that's limiting my guard's development.
