Re: No rumors, Strelka is a clone...

Strelka was able to find the mate, Rybka wasn't. Rybka's +320.00 score is a mate announcement. So it found the mate. Strelka also first considered Qd5, Rybka didn't. Therefore Strelka is not a clone. This is not correct logic. This logic implies that a clone of an engine should produce the same beh...

Re: No rumors, Strelka is a clone...

Both Rybka 1.0 and Strelka don't contain any EGTB code. Though I agree it could be some library code, theoretically. It could be some library code and coincidentally only Rybka 1.0 beta and Strelka have it? No other program. OK we may accept this. What about the positions Uri posted? This has nothi...

Re: No rumors, Strelka is a clone...

Can´t you imagine that it might be just a small typo when writing such hex addresses? In fact the Rybka address range should be 25AC8-27 3 7F hex, and this makes both blocks the same size. Well that makes sense too.... :D (BTW, 6328 bytes - that for your ´basic logic´ ... :wink: ) Yes absolutely. I...

Re: Winboard and chess engines

Howdy! I installed Winboard 4.2.7. When I go to Start->Winboard 4.2.7->Chess Engines I see Crafty 19.3. But I don't understand how to get the other engines to work with Winboard. I extracted an engine called vicki0_031a. I put the executable file in the Winboard 4.2.7 program folder. But I dont see...

Re: No rumors, Strelka is a clone...

It would be better to have a second look at the code of the UCI version by authorities of this club as well as Vas Rajlich himself to settle this issue once and for all. I dislike false accusations, but considering the evidences again, Strelka needs to face a revalidation. Hexcomparison software (o...

Re: Strelka 1.8 UCI released - see differences!

Hi Daniel, I agree - I do not believe this engine is a clone (clown :D ). I am not a programer, but I see a lot of differences in some of my test-positions. See here: I don't know if Strelka is a clone. But if you take the code of an engine and make small changes there will be many positions where ...

Re: Strelka 1.8 UCI released

No I did not try other engines. I invite other posters to do it. Maybe it can help to find clones.

Re: Achilles 3, GM 0.5....

Yes, 3.5 to 0.5, I had a typo mistake. And also yes, I buy the evaluation as second to Rybka because Dgeorge made it. Now the question is...how we can get it? :-) fernando It could be third behind the Rybka and new Strelka. Yes it could. Also it could be 6th. Or even 12th.... But who knows, so who ...
