If it starts to suck your time away, you can stop, or if you run on a crusty
machine, you can find someone else with a machine thats equal to or better to
that machine and let them run it for you.

Vincent has two guys running Diep for him, both of them might have a better
machine than he does.

Even if you run on your own machine, the actual time spent by you,once you get
it running, doesn't have to be anything more than the time spent connecting to
the net and typing an incantation.  You don't have to watch the games if you
don't want to.

That said, I spend a lot of time watching mine, but that's my problem.

For a while I used winboard, which is supposedly the same as xboard.

Bob uses winboard and xboard now.

If you have it fully hooked up to xboard already, it should just be a matter of
passnig in some command-line switches, and it should connect and play
automatically.

You'll need an account on a chess server, from my point of view preferably ICC,
and it will involve a little bit of time to set this up, and to get the lag
compensator (timestamp) installed.  You'll also need some advice about which
environment variables to set so that the humans can do stupid things like do
time or material odds, or only play white, or think forever without worrying
about you calling their flag.

ICC will try to charge you money for this account, but they won't actually take
any from you for a week, and during that week I can probably find someone who
will exempt your account from the fee, since it is an automatic computer account
of a guy who was world champion, a genius researcher at MIT, and it's not "yet
another crafty", blah blah.

Xboard/winboard used to have a gross protocol for resuming an adjourned game, I
don't know how well it works now, but within a day or two of getting going,
you'll need to get this going.

Some of this sounds kind of annoying, but thousands of people have done this in
order to play chess (themselves) on the servers.

If you can figure out enough to connect to ICC with winboard or xboard, and make
a new account, I think the rest can be handled by asking questions there in the
computer chess channel (64).

If any of this is too daunting, or if you are stiing there thinking, "I don't
have time for this arcane crap", hit me with your phone number and I'll call you
and try to make it less annoying.

Once you get ICC-enabled you can play on any chess server in the world, whenver
you want.  You can make new accounts when you get drastically different
machines, and once you are used to doing this it only takes a few minutes.

ICC is at www.chessclub.com.  If you follow their registration instructions, it
won't get you hooked with with winboard/xboard, but it will get your account
going.
