Re: GNU chess in exaequos.com

[Baudaux Benoit]

Hi Antonio,

Thank you very much ! I got 147 correct moves. ELO is then 2518 (on my MacBook 
Pro with Chrome)

I put the iq6.epd file here: /usr/local/share/gnuchess/iq6.epd

I get 171 correct moves with the native version of GNU Chess

I will try other compilation options to see if there is an impact on the 
performance 

Cheers,
Benoit
