Just played my first game on Playchess against a monster Rybka. My machine is an i5-750 stock speed:

NAUM 4.2 is now out.

Thanks a lot Alex for the update!

I have just started to test the new version and I found a speedup till 50 %.
It´s not easy to measure, as I saw the search is different - e.g. different selective depths.

wish you all the best
Werner

[George Bodkin]

Does anybody have a logo for Naum 4.2

Thanks George

Hi,
I think this is the first match Rybka 3 looses ever in our tests for CEGT 40/20:

Code: Select all

1   Naum 4.2 x64 4CPU  +16/-9/=25 57.00%   28.5/50
2   Rybka 3 x64 4CPU   +9/-16/=25 43.00%   21.5/50

Hi,
I think this is the first match Rybka 3 looses ever in our tests for CEGT 40/20:

Code: Select all

1   Naum 4.2 x64 4CPU  +16/-9/=25 57.00%   28.5/50
2   Rybka 3 x64 4CPU   +9/-16/=25 43.00%   21.5/50

Impressive!
And this is _wihout_ Ippo* inspired improvements, right?

[Jouni]

Big difference to IPON list:

Naum 4.2 - Rybka 3 mp (2905) 27.5 - 58.5 31.98%

[Damir]

Yes if you include 1+1 testings...

[Dr.Wael Deeb]

Yes if you include 1+1 testings...

[Werner]

maybe Naum 4.2 was a bit lucky here - we will make more games of course. A match against Rybka 3 x64 2CPU is running. After 12 games Rybka leads 7,5-4,5!
Here is the next result:

Code: Select all

1   Stockfish 1.6 x64 4CPU  +13/-13/=24 50.00%   25.0/50  625.00
2   Naum 4.2 x64 4CPU       +13/-13/=24 50.00%   25.0/50  625.00
