Ok, got shodan grading this sunday, and a question that ALL candidates grading on the day (1st-4th dan) must answer is:

Give examples of torikeshi and how the shushin indicates this to the fighter concerned

I've asked various people including my sensei and get slightly differing responses.

My understanding of it (so far) is:
Torikeshi can be given if yukodatotsu is scored, but followed by bad zanshin or bad etiquette. If this happens shushin criss-crosses flags in front of his/her lower body (??)

Can anyone enlighten me with their offerings please. It would be most appreciated.
