How good is the program vs the man?

True, I don't know about any recent experience like Hydra-Nickel... We may organize something like that with Rybka 3.0 and why not a strong Go engine too, any idea (rules, time control and so on) ?

On this site? Yes it would be funny. I think it will be hard to ask the rybka team?? Have they time? But if some one that we trust can use the computer 30+1 to don┤t get to much electricity. How are inveted to play? The openingsbook Random?

Rybka forum

You may support or discuss the idea of a correspondence chess match between Rybka and a centaur (human + engines) here :

Rybka 3.0 about 2300 at FICGS ?

According to Larry Kaufman from Rybka team in the discussion linked above :

"If we assume that both sides have the same opening book, then I think two things are fairly safe to say: 1. A good human chessplayer (or even a bad one with good centaur skills) + same Rybka will win a long match from unassisted Rybka. 2. In any individual game, the chance of a draw is fairly high. (...) I mean more than half the games, but not way more. The actual draw percentage depends very heavily on the opening book used."

I agree with that, so I assume that Rybka 3.0 thinking at least 24 hours per move would have a correspondence chess rating of about 2300 at FICGS.

Any opinion ?

Godd to know!

Thanks! Ficgs rating is around the same as iccf?

ICCF ratings

Quite hard to say, the rating calculation is not the same, but many players here who started with a strong established rating came from ICCF...

Rybka 2300 @ FICGS

That is interesting Tribault. Do you mean the program running unassisted, no player help, Rybka choose own book moves ? If that is your basis then I say no Way Rybka on FICGS get this rating. There are very many sharp Centaurs playing here. With excellent tuned books. That is the main thing. CC games are won/lost on opening book. I am of the opinion that centaur + program is too strong for Program itself. Results on ICC have demonstrated that. Wayne

Hi Wayne, yes I mean Rybka unassisted and playing with the best book possible. But this assumption of rating was based on games played with a ~2450-2500 centaur... But in my opinion, Rybka would not outplay a centaur rated 2200 as well, so her rating may be closer to 2200-2250.

Finally, maybe the most interesting part would be a match between Rybka 3.0 and a correspondence chess player rated 1900 :)

Rybka vs 1900 man.

Rybka will win that game if the player not are under rankad. But what about 2100 vs computer?

Asked Rybka!

Why they not wanted in corr. The answer was. "Becase the man will also use rybka".
