[b]reading the question and replies makes me see a variety of interpretations of the question:
i dislike the pat answer of 'just do another technique (than the one shown) or 'just hit him' to an uke that is not giving an attack appropriate to the technique demonstrated---why not just pull out a gun and shoot him then? nage would like to practice the technique just demonstrated.
2. asker wanted to know other techniques to do instead of what his instructor showed: answer: any of the above suggestions, or think up your own based on where you both are standing, etc...perhaps a kaiten nage since uke is probably resisting forward motion of his arm/fist by this point, or a sudori sankyo....
CA, First of all, I did not say "just hit him". Atemi is used as balance taker,not as an attack, it never connects with attacker.
Secondly, i was trying to give a point of view on other techniques to use.
Nowhere did asker say nage had to continue to stand. Be prepared to
adapt to any given situation.
