You shouldn't watch TCEC then and don't use any engine but Stockfish because all others are clones of it, even if they don't play the same way, with different depth and nodes.

Yes you are right.

[At least they all use the same ideas but implement them a bit differently. Or they have different bugs.]

+10 and congratulations to have found why!

Calling the integrity of Throsten into question with no evidence is something to be ashamed of.

Congrats to Robert for qualifying for the TCEC Superfinal. I'm excited to test Houdini 5 when it releases.

But that's not how things work on the internet!

I am not talking about Throsten. But engines that might be corrupt for they are not checked. I mean source code inspection.

I do not think anything of value would be determined by source code inspection and here is why:

The strongest engine in the world is Stockfish.
Stockfish is open source.
People can read the code and collect good ideas from it and put those ideas into their programs.

Now, I have no doubts whatsoever of the integrity of the Komodo team.
The engine source code is fully original, and new ideas that are inserted are inserted as new ideas. I say this as someone who has seen several iterations of code after it became commercial.

As for Houdini, Houdini is based on Ivanhoe {IMO - not proven, but it is public domain so fully legal}, not Stockfish. So to insert ideas into Houdini, they will have to be translated into the new framework. Simple cut and paste will simply not work.

And as for Stockfish, the code is right there for you to inspect.

Do you intend to call the integrity of the Andscacs author into question?
The gull author (it is open source)?
The Jonny author?

The casting of aspersions against chess programmers, tournament directors, etc. needs to stop.

IMO-YMMV

And if these engines may not be corrupt they may lack originality. Don't want to discuss originality. Might be that all these engines are copying (Stockfish) ideas I don't know. Probably normal average growth is fifty ELO points a year.

By the way draw rate of the mutual games of the first four engines is very high. Makes me suspicious too.

The higher the rating, the higher the drawrate. You should know that...
