Well, it was at Sugano Sensei's seminar in Phila. He made a great distinction between what you see in kendo (I take it the yoshinkan kamae resembles some of the older kendo kamae) and what you see in aikido. I think he found my stance rather combative.
Of course, this is not the first time I've seen aikikai instructors find the yoshinkan stance anything from rather combatitive, to downright frightening...
It can be rather intense at times.
From what I could understand, the aikido hanmi is concerned with a slight turn of the body from kamaemi stance(upper body and esp. hips facing forward) to a harakami stance (not flat, but not fully forward, angled). This harakami stance protects nage's center, and then the bokken is used to control or capture the center line of the uke.
Buki waza is not my strong point, so take all of this with some spoonfulls of salt, and a little pepper (freshly ground black pepper works best).
