How do rikishi prepare for opponents?

[Barbara Peterson <nocturne_cvs@yahoo.com>]

Does anybody know if the rikishi 'prepare' for their opponents by
watching video tape of previous matches in which their opponent has
lost?  Seems to me Chiyotaikai should be studying some.  Hopefully
he'll do what someone on this list suggested, do something
unpredictable to surprise the guy.

Also, anybody know what the commentator asked Terao during his
interview after making kachi kichi?  He seemed much more calm than
other riskishi I've seen interviewed (perhaps because he wasn't out of
breath) but I'd like to know what he was asked and what he said,
especially that which had him laughing in the end.
