Re: Kotegaeshi, help please
I will have to think about whether this is an all-inclusive rule. I'll stipulate to an exception, since there is always at least one. But yes, we almost always use two atemis in Kote Gaeshi. When we intercept an attack*, we backfist to the face (I prefer the pie-in-the-face, personally), then again right before we execute the throw. This keeps a hostile uke from punching us after the return, or pivot. Also, it gives us a moment to make sure we have the kote.
*For most ichi techniques, Shite initiates with an atemi.
