If they do the chess god will be mad at them. Not only that the chessgod will kick out the chess devil (whom Vas sold his soul to) from Vasik Rajlich's slender body and take the place and make a 50000 elo chess engine.

Exactly. Finally someone who understands me.

I don't saw so much nonsense (technical view) in one thread and also the question is nonsense. if I'm looking to your other questions here, in this sub
forum, i'm not getting smart about your person. :roll:

Rybka is a normal chessengine like Shredder, Fruit and Loop. She used all things like other engines too. The only thing why she is so strong is her very very well tuned evaluation based on material on the board.

So, you can call this Rybka's secret. :lol:

Hi Daniel,

i agree that Kaustubh's questions are unsophisticated - but far from nonsense. Please consider cultural diversity and probably adolescent greenness.
On the Rybka topic, your answer is unsophisticated as well - what is a normal chess engine. Since it is a secret, only Vasik knows - anything else are rumors and speculations.

Cheers,
Gerd

I think that rybka has superior search than most engines and it is not correct to claim that the only reason that rybka is strong is her evaluation.

I agree Uri. There is no way Rybka can be so strong in her QSearch or whatever form of it that Vasik has implemented, by just having more knowledge about material imbalances. At least I don't think it is possible. It is not much more than a guess but maybe a superior evaluation can get two plies deeper out of the Alpha-Beta search alone - and I think that would be a fantastic result if it is actually true! -, if Allessandro's and other's experiments would translate to Rybka and going to bitbases would help too. But I don't think that is enough. Just my opinion but I think that would be too easy.

Did i ever said its only the evaluation ?

I just said she gets the most points from her evaluation. Of course Rybka has a very good pruning and a margin technics which are very well tuned, but basicly she's doing the same like movei in search. (from technics view) :lol:

I think that basically she does better than movei both in search and evaluation.

I am not sure if most of the difference in playing strength is because of better evaluation.

Edit:
for your question you used the word "only" that suggested it is the only reason for her strength.

But this says not that her search is weak compared to other top engines. Its more or less equal compared with top engines. Vas isn't using unknown or new search technics. He just tuned the well known public technics.

At all i must say Vasik does an impressive job. :)
