Arm-In Rear Naked Choke from Seatbelt Control

From back control with a seatbelt grip, Tori attempts a standard rear naked choke, but when Uke defends by “answering the phone” and blocking the choking arm, Tori switches to the Arm-In Rear Naked Choke. Using the outside hand, he controls behind Uke’s elbow and tricep and forcefully pushes that defending arm across Uke’s face, clearing the line. Simultaneously, the choking arm shoots deep under Uke’s armpit, threading across the neck. Tori then grabs his own elbow, brings the secondary hand fully behind Uke’s head, and compresses by squeezing the elbows together and tightening the chest-to-back connection, finishing the choke with Uke’s arm trapped inside.
