That is true if (a) you are very selective in who you play and (b) you don't
play many games to let them discover 'holes' in your book or evaluation.  I have
said before that the 'automatic' programs have a tougher time on ICC, _not_ an
easier time.  Because if they cook my book, they will cook my rating.  A manual
program will just simply lose and disconnect.  And lose one game rather than
20.
