The difference is that in ICC the games are not tournament time control
and the opponents do not prepare seriously for these game like for tournament
time control.

It is interesting to hear if they have the same opinion if the games were
tournament time control and one game for a week so they can play against crafty
at home(of course not with the same opening book) between the games and analyze
the games to learn more about crafty's positional mistakes.
