Gable Grip behind opponents shoulder...Choking arm (back of the hand faces you, other arm palm faces you and forearm runs down the opponents back - squeeze and shrug to finish
you can also go with your hand (back of the hand toward the ceiling) across his throat S grip pinch elbows together and choke that way....sometimes (just to be a D!CK) Ill take my top hook off and drive my knee into the back of their neck shin in the center of the back...
enjoy
