I have seen very, very few Aikidoka who if caught in a square kamae would ever be able to stop a front snap kick when the distance is close enough not to have to step to kick. I am not talking about naive minds, but experienced fighters.
Your general point about not getting too caught up in the external form is a good point that takes a lot of experience in kumite to achieve.
Well Marc, in your previous post from this topic you was talking about YOURSELF delivering a kick. Are you experienced fighter?
