Endgame knowledge of Strelka 1.8 and Rybka 1.1 beta

[James Constance]

No doubt, one easy explanation suggests itself...

You should be ashamed of yourself! We should all be ashamed of ourselves!

I just got up......I still have no answer to my questions from Dann.

I'm starting to think he has not seen the code.

I'm starting to think he just heard about it from Bryan.

Maybe this suggestion will motivate him

As for Gabor.....we don't often agree but in this case I don't think there is the even the width of a cigarette paper between our opinions.

Hi Christopher,
this is wrong and I think you are no more fair.

I have got the compilation of Strelka 1.0 beta which Dann has made - with the mistakes he wrote.

Well that's good then.

It means he can answer my questions to him below.

That data table in Strelka 1.0 is what I want to know about.

[Werner]

did you read that post?

There is also this 6328 bytes block that is common in both Rybka and Strelka, and the status of which is still undecided. Is it a common library? A common block of code? A common block of data? The answer to this question could mean a lot.

I have IDAPro both x32 and x64 at my disposal Werner.

My problem is that i believe (unless I am told different) that the data table in Strelka 1.0 is a set of values or weights used in its eval.

I want to know if this is correct and a little more about that, as I know with certainty, that if those items are the same or very similar to Rybka, I would know how Strelka was made.

Everyone is avoiding this right now but to me...this is something definative.

I know that it is possible to build a lobotomised Rybka like Strelka seems to be with what is available now in the public domain.

The above statement is a complete fact.

If I had just the structure of any engine that has the basic fundamental workings of Rybka, I am very very certain that I too could build a Strelka.

Don't say "why don't you" because it does not interest me but please believe me that I have a very very good idea how that engine was made.

If you read what I asked Dann you will know that in a roundabout way I am asking him for some very specific answers to do with that data.
