Re: different ways of applying kotegaeshi
Is the inward turning of the wrist the basic element of kote gaishi? I've seen some shihan do this technique with only one hand, the hand on the wrist, no hand on top of uke's fingers. And yet uke goes flying. The technique then hinges on the inward turning of the forearm instead.
Maybe we shouldnt be such sticklers for certain physical details and look instead at the principle involved. After all, there are (Hombu-taught) variations of irimi nage that do not involve raising one arm in front of uke's face and cutting down.
