I cannot say how long this test will last. Rolf Bühler is playing on three
identical Athlons 1.3 but the machines are not always running days and
nights. If I would include my Duron 1.3 we would have four machines ...

The games of the series 1) and 6) are already available for download
at our homepage http://www.beepworld.de/members39/utzinger/matches.htm

We had always used 64 MB hash for each program in our matches with CM9
and have not thought about changing this in the running matches. We have
never seen reliable tests [some hundred games!] to prove that more hash
would bring a substantial improvement [how many ELO's] for any program.
This would indeed be an interesting test ... who is willing to do this
work? Perhaps nobody as most people rather like to play [meaningless] blitz
games just to have a lot of games with no interest as far as quality is
concerned.

All games are played under Hiarcs8-GUI as we do not like the new pgn
format.
