Hi Bruce,

I'm not sure what response you hoped for.  I'd like to be able to post
that a friendly millionaire rang the ICCA after reading these messages
and offered to pay the costs of a second, separate, tournament, plus
extra money to allow more rounds in both.  But that didn't happen.
Here's the only response I can offer:

The swiss tournaments aren't exact science.  They are something of a
lottery for first place, let alone 5th, or 10th.  (Program developers
are likely to know that the results from 7 test games could easily be
*very* misleading, since the variability is high.  It's possible to
calculate exact odds given sufficient assumptions about ELO
differences.)

The championships are not a scientific measurement.  They are
(in a sense) a biased lottery, in which programs may participate
if they wish.  The event has to run for a fixed (not too long) length
of time, to keep costs down to that which participants and sponsors
can accept.

Because it's a biased lottery, the better the program one shows up
with, the better the chances of winning.  But there are significant
chances for upsets.

I think this has advantages as well as disadvantages.  It drives up
the motivation to squeeze the very best from the software and hardware.
It offers newcomers more motivation too - they might get lucky on
the day.  It increases excitement for spectators (at the expense of
stress for participants).

Given all this, it seems to me that it isn't worth worrying about the
somewhat greater uncertainties associated with a "best micro" title
compared to the "best of all" title.

Yes, we could cut out the micro title from this championship, but as
we can't offer a separate micro championship this year, we would be
reducing the opportunities for those people who have deliberately
aimed at that title as opposed to the open title.  (And reducing the
excitement level.)

We can't please everyone.  (Unless that millionaire can be found :-))

Don Beal.
