Taking ukemi from a shihan like the late Yamaguchi Seigo Sensei.
Sometimes shihans will do a technique, allow the partner to take ukemi, stand up, recover and then make another attack.
Yamaguchi Sensei's aikido was much more open-ended and fluid. As you were coming out of one technique, the opening for the next was already there. You had the fleeting choice of seizing the opening, or exploring other possibilities. In either case, a new and usually unexpected technique would result, and another opening... And so on for a number of minutes.
