Re: GNU chess in exaequos.com

[Antonio Ceballos]

Hi Benoit,

The program is strong indeed. I am too weak for it too.

You can compute its approximate rating (ELO like, but of course, not ELO) as
described in test/iq6.epd. The file is not in the published tarball, but
you can
download it from git:

https://git.savannah.gnu.org/cgit/chess.git/tree/test/iq6.epd

Run gnuchess, and then enter the following commands:

st 10
solve iq6.epd

Replace 'iq6.epd' by the complete path where the file is placed, e.g.
'~/Downloads/iq6.epd'.
It will take GNU Chess slightly longer than half an hour to solve the 188
positions contained
in the file.

Once it is done, you will get a result like this:

Correct=160 Total=188

Then, apply the following formula to compute the score:

score = (percent_correct x 6.7) + 1995

For instance:

160/188*100 + 1995 = 2565

The score you will get depends on your hardware.

There are ways to make GNU Chess play online games against other computer
or human players, but it is more difficult.

Have fun!

Cheers,
Antonio
