Hi all

,
our updated rating lists are now online and can be found under the attached links.

40 / 120:
No update this week but new interim results in our forum:

CEGT 40/400 repeated 2008

Code: Select all

1   Rybka 3 x64 4CPU  ½1½½½1½½½½½½½½½1½½½½0½1½½½½½ 15.5/28 
2   Naum 4 x64 4CPU   ½0½½½0½½½½½½½½½0½½½½1½0½½½½½ 12.5/28

Code: Select all

1   Rybka 3 Human x64 4CPU  ½½½1½10½½½½½1½½1½½½½½½½10½½½½½ 16.5/30 
2   Naum 4 x64 4CPU         ½½½0½01½½½½½0½½0½½½½½½½01½½½½½ 13.5/30

Two things are striking so far. The draw percentage is extremely high, around 80% from both matches combined. Naum 4 seems to be closer to Rybka 3 with very long time controls corresponding to 40/120 on more than three times faster hardware. More games are needed as always to be sure, but maybe some correspondence players will start to think about Naum 4 as an alternative to Rybka 3 for very long analyses.

40 / 20:
This week we added 1499 games to our list. See more in our list "Games of the week". In total our 40/20 list is based now on 309.116 games.

New engines:
Stockfish 1.2default x64 4CPU had a good start with 3024 elos after 88 games. Its 100 over 2CPU and so I think this start rating is too high.

Crafty 22.9 x64 2CPU shows an improvement of +100 over 1CPU-version too: but 2768 elos after 72 games cannot be hold with more games !

Tornado 2.2 x64 1CPU is 82 points better than version 2.1.37a but of course we compare a 64bit engine with a 32bit. Congrats to Engin - he could improve his engine once more in a short time.

and now the updates:
