2 Part Technique - Marcelo's Seatbelt Control is fastened with a thumbless Ball-N-Socket Grip; the fist of your choking arm is enveloped, leaving no edge for your opponent to grab onto. Anticipate his roll from Turtle, and leap over his body, sitting him up to set your first hook. If you encounter difficulty setting in the second hook, use the seatbelt and your bottom hook to stretch him out, making enough room for the top hook. When finishing the Rear Naked, keep both palms facing you, rather than leaving a palm on the back of his head for him to reach and peel off the choke.
