I saw a clip a few weeks ago where an Asian(John) was pummelled by a black

guy(Tyrone) on a New York subway train. Tyrone was fit and about 3 inches taller

and John was no match. As John gave up fighting and turned away, protecting his

head with his hands, Tyrone threw his right arm around John's neck and put him

to sleep with a rear naked choke. Tyrone might know some Jiu-Jitsu, it occrred to

me at the time.

John could not turn to face Tyrone to break the choke because the latter's chest

was on his back and his own shoulder was in the way.

Today, I learnt (actually re-learnt) the defense where John could just raise and

swing his _right_ arm downward between their bodies and use the momentum to turn

in Tyrone's hold. The arm-swing would grease the right shoulder and John could

end up in a very good position for a hip throw.
