OK. I think that if the engine have a lot of betters knows about chess the engine have good results... in semi old cpu...
I´m do a underclocking on a ( 820 D normal speed 2,8 Ghz dual ) to converter it on a more slowly cpu, and more realist for a lot of players...
underclocking to 2,1 Ghz.... in that speed other modules have a good speed and a lot of Kn/s... but... the results are very impact_ing for me...
in other hand... I do a fast times... because if rybka have more time... ( cpu run in underclocking and... ) ... eat other engines...
time controls: 4'+2" for game+move.... this is a fast control ideal for engines on mode fritz... kn/s...
