Bob, are you able to draw any conclsions yet on this experiment? It seems as
predicted by many, players are able to spike ratings by creating sub pools of
players on any given account. Meaning if you don't allow all players to play all
players you corrupt the ratings pool.
This would make most if not all online ratings meaningless if true.

8: scrappy is only playing humans. crafty plays anything. This is an
experiment to see how avoiding computers affects the overall rating. If you
operate a computer and don't like this policy, tough.
9: crafty and scrappy use the same identical hardware and software
configurations. Feel free to play crafty so long as you follow its finger
notes.

4: hours online: 39,940; percent of life online: 78%
5: Crafty is freely available, both source and a windows executable, for those
that don't have unix machines they can compile on.
6: anonymous ftp to ftp.cis.uab.edu/pub/hyatt
7: note that I +noplay computers without notes giving their hardware/software,
or computers that don't play an even number of games. This also includes anyone
matching me while having !computer in their formula.
8: computer policy: no more than 4 blitz or 2 standard games by any one
program in Crafty's 20-game history here.
9: I do not expect to see games vs 6 different chess tiger clones. It is your
responsibility to know/find out the name of the program that others use to avoid
falling into this trap. The last opponent gets +noplayed.
10: (2) do not interrupt human games under any circumstances. I am mainly
interested in playing strong humans, but will allow computers to play so long as
they don't monopolize crafty's time. Beware.
