This is a choke from the sitting back position, (and it’s very similar to the clock choke.)
With your top hand, try to get a deep lapel grip. do this but sliding your thumb under the lapel, pointing your knuckles up and sliding your hand as far up the lapel as you can to get a deep grip. try to flick the guys chin up with a turning motion of your wrist. If you get a bad grip, don’t be too discouraged, you can still finish, it will just take more patience.
Next get a decent, but not too high grip with the other hand, the bottom hand.
Lean over to your side and you pull your tom-grip arms, elbow hard to your hip as you drop your head and get ear to ear.
Finish by giving a had hug as you squeeze, turning your choking grip arm, pulling your elbow closer to your hip, and extending your other arm at the elbow to tighten the lapel.
I think it’s easier to finish this choke by also pulling your bottom hand up into your opponents neck as you pull back with that arm. You donlt have to wait for the lapel to do all the work. Hug the neck with this hand hard by trying to touch your fingertips to the back of their neck.
IF you can’t get the grip, attach with a backward eziekel choke:
S grip your hands.
post your top-arm-side foot on their hip hip
spin your arms as you push with your foot. (You’re spinning to a positions similar to the Bow-and-Arrow position)
Get the Eziekel, gripping inside your back hands sleeve
Rotate your back hand around to the near side of their neck.
Choke, by pushing this had forward into the side of their neck. (Make sure your far hand wrist bone is perpendiculal to thier neck to get the pincher-like pressure here which is the finish)
