Subject: New Tao Book

Author: Rosa Ponselle

Date: 09:29:20 02/24/03


Talked to Bas about making a new book for Tao as I've always felt that Tao's
opening book let's it down. Anyway here are some results for a new book I've
created. These are the latest as earlier results with the evolving book were
less conclusive (not that 60 games is conclusive)!

With Tao's original book.

Tao54 - Delfi 4.0 7.0 - 13.0 +5/-11/=4 35.00%
Tao54 - Green Light Chess v2.18 4.5 - 15.5 +1/-12/=7 22.50%
Tao54 - Pepito v1.59 (Agresivo) 8.0 - 12.0 +6/-10/=4 40.00%

With the book I've created.

Tao54 - Delfi 4.0 10.0 - 10.0 +9/-9/=2 50.00%
Tao54 - Green Light Chess v2.18 12.5 - 7.5 +8/-3/=9 62.50%
Tao54 - Pepito v1.59 (Agresivo) 10.0 - 10.0 +8/-8/=4 50.00%


These games are on a PIII 700 at 5 minutes a game with 64 mb hash run under
winboard.

GLC uses the 2600.book available from the author's website.

Pepito also uses the default book available for download from the author's site
and had learning turned on. The book was reset between matches.

I know the numbers are small but I'm currently running more games and will
include results for Ruffian and Yace (also planning LG 3.9/Pharaon/Aristarch).

The book can be downloaded at

I would appreciate if games played with this book could be emailed back to me
(at the email included in the readme with the download). The book still needs
tuning and I will release updates as I work on it.
