Subject: Re: Strange indeed? My tests have shredder7 60-80 elo stronger

Go up one level in this thread


In my testing I am seeing a big difference between Shredder 7 Classic & Shredder
7 CB [over a 100 ELO gap between Shredder 7 Classic (311 games) & Shredder 7 CB
(193 games)].  In all games I am using the opening book which came with the
engine, set to the Tournament setting.

Shredder 7 UCI is 8% faster than Shredder 7 CB in any GUI.  But this does not
account for the majority of the difference.

The big difference between CB GUI & Classic GUI is the way Sandro Necchi's book
"learns" and "chooses" its move.  The book seems to be well suited to the
Classic GUI but NOT to the CB GUI.  I intend to test this hypothesis by using a
"common" specially prepared opening book or use the Nunn opening positions to
compare Shredder 7 Classic GUI & Shredder 7 CB GUI.

I am using auto232 using a null modem cable for tests between different GUIs on
a single PC.
