1 Part Technique - Hold onto your opponent's back with Seatbelt Control, specifically with a Ball-N-Socket Grip centered directly in the middle of his chest. Despite the fact that if you lay on the side of your underhook'ed arm your opponent has an escape route, you benefit in the ability to actively shoot your overhooking arm under his neck for the choke. You can always step your hook to the mat and push back over to the safe-side, but if he fights back to his escape, fire your hand through and clasp his shoulder. To finish the Rear Naked, step on the mat to bounce him up enough to place your arms in a figure-four configuration for the finishing pressure.
