Subject: Macintosh chess engine tournament (ExaChess) progress

Author: Richard A. Fowell

Date: 22:50:03 12/26/00


I've completed most of the games in my ExaChess tournament.

Sigma Chess is doing the best, so far
(though that might change if I can get Crafty going).

I'll  post the games on a web site in a while.

Time control is 5 seconds/move, 100 games per pairing.
In a couple of cases, I played more than 100
games - in these cases I'm using the first 100 games for scoring.

The two engines I haven't started matches with yet are
Crafty (since I need to configure it) and ZZZZZZ (since I haven't had any luck
getting it to play).


Programs:

Sigma Chess 5.1.3      (modified from 5.1.2 to remove "EP" indicator from en
passant capture)
MacChess 4.0e             (standard distibution, except for using MacChess 5.0
opening book)
Screamer B56               (modified from released distribution to adhere to
strict time limits)
Vanessa Chess 2.01x   (modified from released distribution to adhere to strict
time limits)

         | Sigma       | MacChess       Screamer     Vanessa

Screamer | XXXXXXXXXXX   XXXXXXXXXXX  XXXXXXXXXXX    78   - 23
