3 Part Technique - Feed the collar to your over arm from Seat Belt control and initiate the best grip possible to start the submissions. Push the opponent's blocking hand away and zip the choking grip up the collar for a tighter choke. Dig your under arm far behind the opponent's neck and push against his head, while pulling his collar for the Collar Choke. If the opponent refuses to allow your under arm to go behind his heck, switch to the Bow and Arrow Choke instead. Holding the opponent's leg underneath his knee is more controlling than just holding the Gi fabric.
