2 Part Technique - Since the Seatbelt Control is an asymmetrical hold in terms of mirroring left and right, laying on the side of your underhook lends itself to a greater chance of escape for your opponent, but an easier time at attacking his neck. Begin setting up the Bow-N-Arrow Choke from Back by gaining a grip on his collar with your top hand, and pulling the sharp edge of the gi across his throat when he attempts to escape. Use your top foot to help push your bottom hook across his belly and then rock yourself up as you move your underhook from his armpit to his near knee. If you miss his knee, sit up into technical mount to lean over and reach his leg for the finish.
