The Lokasoft rating match

[Werner]

Hi,
I started a tournament between the strongest Lokasoft engines for CEGT 40/20 using ert-tool from ChessPartner 6:

Ktulu 9
Smarthink 1.1 Moscow
Chess Tiger 2007.1
Ktulu 8

eng-eng, ponder off, 256 MB hash, 300 games.

[Kaj Soderberg]

Cool. Interesting to see how good Ktulu 9 is.

BTW I read in an interview with Christophe Theron that Chess Tiger is designed to work best with a hash table size that can be divided by 12.
256mb does not. Maybe you could change the hash size for Tiger, to know for sure that it does its best job.

Best regards,
Kaj

Hi,
thanks for the tip - but inside CP the Chess Tiger automatic uses 192 MB - I forgot to mention.
Here is a first imression:

Just 18 games yet so far,but it seems that the 4 engines are pretty close in strength....
