Sorry , this video is impractical in showing kote gaeshi as a defence against a pin.. Why would anyone pinned on their back face up try a kote gaeshi movement when there are openings for various arm locks?Any seasoned grappler /judoka would avoid the kote gaeshi attempt.Similarly the average judoka would not apply kote gaeshi.May I also state that in general Judoka do not use kote gaeshi in ne waza.
