I choose to not play unrated, to try to make the games "serious".  Since most
there treasure rating points, rated games tend to be more serious games.  Also,
I have seen "scams" where someone "fishes" by playing unrated games until they
find a way to force a program to follow a bad book line, then they will play a
rated game and win.  Also there is a problem with playing rated as white, then
an unrated when you get black, then rated with white, etc...
