Subject: Tournament Format for World Computer Chess Championship 2004

The tournament format for WCCC that was originally decided was:

--------
http://www.cs.unimaas.nl/icga/news/events/Israel/event.html

The format for the 12th World Computer Chess Championship WCCC2004 will be:
5-round Swiss, after which the top 4 + 4 teams get to play a 2-round elimination
at each stage, and the bottom teams continue to compete for the 9th spot playing
a 6-round Swiss.
--------

However, since a large number of amateur programmers expressed their disapproval
of this system, we have decided to change the format so that it will attract the
largest number of programmers. Currently the two options are:

A) Like the original format, but with re-entry:

Divide the participants into two groups. Conduct 5 rounds Swiss, and top 4 from
each group (total of 8) will qualify for next stage, which will be a knockout (2
rounds quarter-final, 2 rounds semi-final, 2 rounds final). The other programs
will continue with 6 more Swiss rounds. However, the *difference* is: the losers
in the knockout will join the other programs (who haven't qualified for knockout
phase) in continuing with additional Swiss rounds (with all the points they
scored in the first 5 rounds and in the knockout phase).

The advantage of this method over the original one is that the amateurs will get
more chances of playing against commercial programs after the first 5 rounds.

B) 11 rounds Swiss.

In Graz WCCC everything was basically over after 7 rounds. The last 4 rounds
didn't change anything at all. That is the reason why we are trying to choose a
more exciting format.

However, our primary goal is maximizing participation. So, if 11 rounds Swiss
will attract the largest number of participants, then we will opt for it.


We are interested in hearing your opinion, especially the opinion of programmers
who are considering participation in WCCC.
