If during the setting up the opponent wraps his pinky finger around your wrist, then you have to direct all pressure from your wrist to that pinky finger.

After Ready Go, with a quick move towards yourself, extend the opponent’s finger, while holding his palm strongly with your fingers.

With a sideways movement towards yourself, direct opponent’s arm towards pad.

Pin the opponent’s arm. Remember to pull your opponent’s fingers all the time, so that they cannot counter.
