"Tori sits astride Uke. Uke pushes Tori
with Uke's right arm.
Tori
encircles Uke's right arm, using his left arm, pressing against
Uke's upper arm with his forearm. Tori rolls to Tori's left,
sitting close to his own left heel. Tori locks the fingers of
both hands together,
Tori
presses down on Uke using his right leg in order to retain control
of Uke, Tori presses directly upwards using his left forearm
and right hand. The upward thrust of Tori's forearm on Uke's
muscles should bring about a quick submission The more Tori
rolls to the left the more effective the lock will become."
