2 Part Technique - Hand Fighting for the Rear Naked Choke seems complicated, but with practice it will eventually become second nature and an invaluable method of attack from the Back. Monitor the tightness of your Seatbelt Control based on whether or not your opponent is trying hard to escape, otherwise you run the risk of tiring out your arms. Falling to the under-side, trap his arm with your top hook and remove his other arm from the equation with 1on1 Wrist Control. If you cannot slide under his chin to finish the choke, use your choking hand to grab his wrist while you pull back his forehead with the other hand. When the gap is large enough, slingshot the wristbone of your choking hand under his chin and look to finish.
