Re: What is the correct hand placement when do kote gaeshi?
I'm practicing aikido aikikai, I should mention these two videos are not comparable. The aikikai one (by Mike Jones) is just demonstration of very basic Kotegaeshi and the other one is about variation of kotegaeshi, which it was really helpful for me (I appreciate it).
In aikido clips and variation of techniques don't try to compare but try to feel the differences and learn different forms of a single technique. I always see it this way.
