Favorite: Arm Triangle - This is one I work for off of mount or side control, usually by setting up with a kimura or americana.
Best: Rear Naked Choke - Simple and effective.
Worst: Triangle Choke (with the legs) - My legs are short and thick... I have a real hard time trying to finish properly with a standard triangle.
It doesn't matter if you agree or disagree
... As long as I don't bore you and I spark a moment of thought, my goal is achieved
