Cool stuff Mike , this should be fun
I take the name fairly literally , I have perhaps come up with my applications becasue i see it as ways to deal with a very strong guard , someone you cant overpower with strikes etc .
Move number one
I see the hand in fist position usually as a grab or a counter grab .
you have there right wrist or they yours in a same side grab ( maybe you grabbed there jewels )
you latch on with both hands
You rotate back , using your body torque to extend there arm , you use your grip and postion it in a double hand wrist lock , the rotation and angle of the arm minimises there ability to strike with the other arm .
You rotate back executing the wrist lock while driving forward , the combination of both drives him flat towards the ground .
this si a great way to execute a wrist lock IMHO , I`m not big on them but Ive used this and it`s doable .
A less complicated move is too do the same move , draw the arm or whatever is in the way maybe grabbed wrist again , maybe a chest grab etc .
Grab with with the left arm then spring forward with the rotation shouldering and coming over the limb to the back fist .
you get quite the charge ,a nd because there resisiting your pull you get a big straike and shoulder .
most imporatntly its a dominant entry .
So basically Mike Mines the same as yours , except I see the initial rotation as a draw , utilising both the sinking and the rotation to pull them out of there base or at least to gain resistance . The attack is a jam IMHO , the reinfocing arm controlling the limb while the connected mass drives over it with the other to make the impact .
Just a couple variations , It can work on the otherside going up the middle too .
