There are just endless variations of kokyunage from yokomenuchi. There is only one place that I have practiced something like this before… almost forgot about it, but thankfully I stumbled upon this video (please mute the volume first). The key observations are keeping connected with your partner, not with limp sticky hands, but with relaxed tension that comes from matching the inertia of your partner.

The cut-downs in this clip are inline with my philosophy about kuzushi (which can get overlooked in normal practice).

This kind of partner practice is a dream of mine, and I finally got to play like this last seminar. 普通稽古の間ではこんな稽古をやりたいな。
