I knew that Shirakawa Shihan is the best aikido master in the world and that he would do it. But only today I realized how kind and good a person he is. Great movie. Thank you.
When the opponent is larger the strategy has to be precise. What works is to apply where you are strongest to where they are weakest. Otherwise the stronger person wins. Every human body, is weak to lateral pressure to small joints. That is key. The advantage of the smaller body is that it can move in space faster, its center of gravity is lower, and it can defend against joint attacks easier. The only chance is to apply all these strengths against the weakest points of the larger person.
