Couple weeks ago, someone posted a question on Reddit asking how Uchimata from outside position in Kenkayotsu is done. Interestingly enough I taught a similar concept just a month before the question was posted. After asking the poster why he thought inside position stiff arm can stop Uchimata, this was the response.
“I was told and I feel that the uke can use the inside position and create a barrier between uke and tori with his stiff arm to create distance between the Tori and uke when Tori tries to go in for a throw. If that is case, how can tori still throw if there is a barrier in between them that is creating huge amount space between them? Also it seems to me that the tori is still able to throw uke, even while uke has the stiff arms out in kenka. What details am I missing that allows this to happen?”
I didn’t know a good way to explain it through text so I told them I would make a video on it. Here is the video.
