Rule of thumbs:

If you end up with an opportunity to manipulate a wrist but are not sure where to go with it, remember to move towards the thumb in the direction that is already pointing in:

  • If the person’s palm is facing down, twist the hand counterclockwise and forcefully flex and evert it so that the thumb points down and then to the outside.
  • If the person’s hand is facing palm up, turn the hand clockwise and forcefully extend and invert it.

Being able to turn the wrist forcefully  into it’s limited range of motion is more important than the other elements. Experimenting with a  compliant partner will let you develop a feel for how to transition between the two as he tries to turn away from the force.  Experimenting with a non-compliant partner who is trying to hit repeatedly you will point out how unreliable this as as a primary defense.

Consider using the momentary control of the wrist to achieve further ends:

  • explosively jerk the arm while moving backwards and lowering your COG until they are face down
  • fold the arm into their body and get control of the shoulder and neck
  • use the captured hand as an anchor while attacking with the other arm and legs

Once control of the wrist is established, take the first opportunity to  attack rather than focus on fighting for continued control of a single limb.  The goal is to put the person on the floor or pin against a wall as opposed to struggling for standing control, where they may strike you, regain their COG and use the legs for assistance.

That being said, if the initial wrist control is immobilizing,  keep it. But don’t count on it.
