Very briefly, there are two scenarios that are imaginable why there is fruit code (or let's say, algorithms) in Strelka.

1. They were there in the first place in Rybka and got disassembled and reconstructed.

2. Not everything was possible to be reconstructed from the disassembled data (quite likely) and missing stuff was "fixed" with the help of the freely available source of a strong chess engine.

Now everybody blames Vas for borrowing from Fruit, but actually scenario 2 makes more sense in my opinion.
Also for you I am willing to explain the evident.

This is a crime case. And to analyse such a case, it's sub-optimal, to say the least, to discuss on the basis of the criminal offender.

In clear-text:

This anonymous Osipov figure announced in advance what he wanted to achieve (to prove). That namely Rybka is nothing but Fruit. And dont you see with your own thinking now that by falling into the trap of only analysing the scientifically neutral question where this strange Fruit code could have come from - if the Strelka guy "just" decompiled Rybka - and if that wouldnt prove that Rybka is Fruit-like, you intentiously or by weak thinking or by negligence, you support the original evil and criminal idea which said that Rybka is nothing but a Fruit clone?

This is why I told expert Corbit to forgetz about some technical difficulties to understand the situation and to better help solving the crime case as such.

We must find an agreement among the honest memberts of the community how we want to deal with such evil attacks from hiding places, where someone anonymously is trying to publish the secrets of an honest member like Vas under the pretense that Vas has himself commited something illegal or unallowed. That is basically the idea behind the Strelka event. We should agree that this sort of blackmail and treason is banned from our community and that if someone dares to follow such paths - also in joking on a forum - he is heavily discriminated and punished with social refusal and ethical contempt.

Let me give you another example out of crimes. In case of a sexual child abuser it's also possible to then proceed with extended analysing of a possible wrong on the side of the child who might have provoked the interest of the perpretator with a very short shirt. But would you personally see an excuse in such discussions? A court and a judge might need these arguments before they speak a verdict, but in a community like ours that aspect doesnt change the fact that a member would be a child molester. And that it's a misbehavior we dont want to have here. In special if the offender (under the mask of a decent under cover agent) is eagerly interested in hiding himself. The point is that if that what he means is so clear and obvious, then he had nothing to fear and he could expect all thanks from everywhere. Here you see the psychopathic structure of the whole case. Here someone wants to pretend he's sober but he must remain anonymous for reasons that are not normal.

If questions to all this please ask.

But I don't want to discuss with you about a (probable) crime case. There are other threads about that. I directly responded to the question of Dann, which I even quoted above:

I stayed perfectly on topic of this thread. Point.

I gave two scenarios. Both are possible. I didn't give any bias to which I consider is true. I said that there are ideas from fruit in the Strelka that could also be in Rybka. I didn't say Rybka is nothing than a Fruit clone.

Lies.
No, Osipov asked Vas more than once for permission to commericalize Strelka, and was turned down (refused).

How can anyone know that besides Osipov and Rajlich?
Not that I understand why he should ask for permission.
I saw the correspondence.

Well, perhaps you can see the connection between a former public declaration of "threatening" to publish the source code and the gossip/theory of Rybka's origines AND now such a question for permission?

As a general remark let me add this: I think such questions here are very important, if then they can be answered with all clarity. It would really be a desaster if people would be afraid of asking further questions only because they would have to fear social consequences. This continual movement of asking and responding is the main reason for the existence of such a forum. Someone once made the comment that there dont exist "stupid" questions but only stupid answers, if at all.

Rybka is a bitboard engine.
Fruit is not.
Cloning as we currently understand it means copy and use the same lines and data 1:1.
Since Fruit is not bitboard, how could Rybka ever be a Fruit clone? It might very well have a fruit inspired search but that is true for all engines which have been released in the past years since Fruit arrived on the scene.

I may be sceptic but I simply don't see why I should trust Rajlich's statements more than those of Osipov. I don't know either of them and I am sure that hardly anyone here knows them adequately. All discussion should remain on the area of facts, not opinions and claims.

This is the crucial point right from the start of this conflict. So you would trust an anonymous figure as much as you would trust the programmer of the best engine in computerchess? You've made clear the point, but now you lose all arguments with your position. You speak about facts, yes, good one. But is a pseudo the same fact as a well known and respected person? You cant mean that! Please reconsider your position.

You should be careful about your assumptions. What I wrote is fact.
