Re: Octagon GUI used in https://www.twitch.tv/navratil25

You would have to ask the GUI's other author. I would like to see the Octagon GUI code open-sourced and distributed with a free license allowing the distribution of modified versions. But if Alain Bellon doesn't want his code released, it would be improper to do so, no matter if you did contribute s...

Re: Ethereal question ... with or without NNUE is unclear!

As an Ethereal dev, I'll chime in and say the regular Ethereal 12.75 (or newer) should compete. The "SF NNUE" branch has some interesting properties. Demonstrating how easy it is to copy NNUE and giving one way to assess how much of the difference of strength between engine comes from eval vs search...

Re: 1.g4 opening is losing?

CDBCN reached -152cp after 1.g4 d5. The DB doesn't allow to easily find how many positions are present in this position's subtree, but it has kept on expanding and no good defense for white has stuck. This doesn't exclude the possibility of one extremely precise line that would draw but gets too inc...

Re: CTF Survey

I vote 1. I never read or write in CTF. But I don't see why people not active there should get to close it. It's not visible to non-members, and if you are not interested, do like me, don't read it. The only spill-offs I have seen have been from some people who complain that dictatorial management i...

Re: Why does TCEC use unbalanced opening?

Of course the engine that wins a game pair demonstrates superiority in the opening played in that game pair, I never said otherwise. And a good engine should be able to handle a wide variety of positions, so this tells something about general superiority too. :)

Re: Why does TCEC use unbalanced opening?

If an engine cannot take an 'edge' or unbalanced position and turn it into a winning game...it does not deserve to be considered a good engine. Simple. You got it wrong. You can only win a game of chess from a balanced position if your opponent make mistakes. You can play more challenging moves to ...

Re: 87% of the poll voted that SF will win Tcec Sufi 19.

Leela starting eval as white in the opening pair it won : 0.50 Leela starting eval as white in the opening pairs Stockfish won : 0.44, 0.41, 0.46, 0.47, 0.38, 0.34, 0.49, 0.36. You read it right, Leela gave a higher exit eval to the position where it won a minimatch than to the 8 where it lost the m...

Re: Dangerous turn

It's funny to see you defend this, because Scorpio is going to be crushed by the NNUE flood and low-effort eval copies. So many ways of copying other engines/architectures are completely fine to make your hobby engine but are not fine to compete at TCEC and shouldn't be fine to be presented in ratin...

Re: Dangerous turn

Anybody is free to make whatever fork or copy they want, but TCEC needs to deal with what's allowed to compete in their tournament.

Re: Final Release of Ethereal, V12.75

It's not "a new evaluation term". A new evalution term doesn't discard the rest of the eval, it doesn't kill eval originality. It's a drop-in eval replacement. Is there no way for originality in NNUE development? Someone could attempt to have significantly different input features (so far no one ha...
