My program has played on FICS on rare occasions, and running under Xboard was a
lot more fun that running manually. Also if you play bullet or fast lightning
manually you'll lose on time more often than not against automatic programs and
a few of the fastest humans.

Another reason is that some of these operators might have an interest in the
programming side of computer chess but lack the skill, dedication, or bravery
needed to write a whole program themselves.

So you think a knight is really worth as much as a rook? You can probably find
the right place in the Crafty sources in 5 minutes. 5 more more minutes and
you've recompiled and you're back playing on the server to find out.

You've thought of a wonderful way to do R=5 null move without missing anything
important, but you want to test it a bit before you tell the world? It could
take you anything from 5 minutes to a couple of days depending on how tricky it
is.

You wonder how good the results will be if a program drops a pawn in some random
way sometime in the first 10 moves, but then plays the rest of the game well?
Again it's probably not too hard to cripple Crafty in this way. (This is
probably why Bob gets annoyed at people boasting that they beat a Crafty when it
turns out it wasn't the "one true Crafty".)

All of these would be difficult or impossible on the best selling commercial
programs. A program that plays within a few hundred points of the best chess
there is, and is debugged and ready for automatic play, and is available with
full source code and reasonable comments, is a great resource for anyone who
wants to hack computer chess just a bit without writing a whole program. (But
writing your own program is more fun :-)
