It baffles me how people can complain about anything.  I mean, it is your right
to determine how you want to set up your account.  I mean, not only is it your
account, you wrote the damn program.  If you wanted it to play only humans
everyday and take sundays off to play with its self, then that would be your
right.  But I think like suckers, there are idiots born every minute too, and
the people that complain and accuse people of being greedy about rating points
are, well, quite idiotic.  Bob's crafty won't be getting invites to Linares
because of his 3100 rating.  I doubt Kasparov will be lining up to play a world
championship match due to it (too bad! :)))) ) and sitting on top of the ICC
rating list won't make extra sales for the engine since it is free.  So, pray
tell, what point would there be of being greedy?

Before Rebel Tiger came out, Dr. Hyatt was quite flexible about which computer
would play it, as long as its not a crafty, now that you have all these
2400,2500 type comp accounts playing with this new automated strong engine, you
have a rather narrow formula.

Lastly, personally I can not understand why (and this doesn't apply to you
possibly) some owner of commercial engines would take enjoyment of playing 14
games in a row against an engine (winning 12) and taking these rating points.
Who are the greedy people in this instance.

Jason

PS My above statements are not directed at the engine but rather some of the
people who use it online and act like twits.
