I remembered I had a video of myself competing a couple of years ago under the old rules system of Judo against a very powerful foreign Judoka, (we are being reffed here by a 5th or 6th Dan from a Japanese University club and the officials chair had older more senior judoka from Japan so I felt quite privileged to compete). You will see I am not playing conventional Judo but rather my own style which uses "surprise, tricking someone (feigning), overpower the opponent, making him commit mistakes." I do not understand all of what 'jû' is but every person of skill who has trained with me invariably comment that my wrestling style is very energy efficient which I think is part of this.
My opponent was attempting to use his superior size, strength and experience to stiff arm me into a mistake. In his prior matches on the day he stiff armed to unchi mata everyone else in under a minute. I employed my radical tactical adjustment theory and engaged him in a manner which did not rely on grip against grip fighting but rather deflection of power, angles and speed. It is the first match in this vid:
For the OP the key for me is to not let them settle the stiff arm before you move the shoulder they are gripping either under them or backwards as you twist your body, lesson for me is you cannot fight superior power with inferior power so do something else.
Thanks for posting this. This is, of course, shiai, not randori. No need to worry about jû ... in a sense that no one does shiai to show jû, but to whn. That is normal. Besides things such a jû is for late in one's career really past competitive career. It just takes too long to master. YOu applied good strategy taking into account hte properties of the opponent. The wrestling background is obvious from your posture. An alternative would have been to drive up the pace; he would not have been able to follow you. The positions of both athletes remain fairly statical throughout the fight. Being more dynamic means more challenge to the endurance system, which could present a problem if one's endurance isn't particularly strong or if one still has some heavy matches to come. So, you provided responses that work indeed, but pedagogically my advice would be for the original poster in randori (not shiai) to not be seduced by these and instead focuse on being dynamic and tai-sabai, etc. He needs to build a foundation, otherwise he will uitmatly fail.
