Re: Kokyu Nage techniques do they work?
My knee-jerk reaction is to say, "Yes, they do work," but I really don't have the experience...
How about this: If uke's balance isn't taken (and/or uke doen't stay connected), shouldn't nage be in a position where there is an immediate opportunity for atemi-waza? Maybe a different throw? While the kokyu nage may not work, wouldn't formal technique still set the stage for a viable self-defense?
