Re: Any recent examples of strong programs losing with white at longer time controls?

SSDF time control is 40 moves/2 hours followed by 20 moves/each following hour. They generally use the engine's own book, if it has one, but I am not clear what they do for engines like Stockfish that have no official book.

Re: Any recent examples of strong programs losing with white at longer time controls?

There are quite a few examples from correspondence games and computer-computer play. Just one for example: [Event "SSDF-match"] [Site "Sundsvall"] [Date "2020.09.30"] [Round "35"] [White "Komodo 14 x64 1800X"] [Black "Stockfish 12 NNUE x64 1800X"] [Result "0-1"] [ECO "A29"] [PlyCount "114"] [EventDa...

Re: One for Andrew Grant et al. - NNUE?

I have never been in computer chess to win competitions or top rating lists. I accept that other people have that motivation but it is not what has kept me going all these years. People are still worried that someone will top them because they have some secret sauce, or some borrowed sauce. If you a...

Re: correspondence chess in the age of NNUE

The draw rate in top-level correspondence chess (world championship tournaments for example) is already in the 90% range I think.

stockfish NNUE question

What is the function of Features::Side::kFriend? This is defined as:

enum class Side {
kFriend // side to move
};

and it is used as template parameter. But isn't this just a constant, since Side has only one value defined? How is it the "side to move?"

Re: Evaluation reflections

I would add that a good reliable testing regimen is essential. That means running actual games and enough of them to get a significant SPRT.

Re: It's NNUE era (sharing my thoughts)

It is pretty well established I think that both search and eval are important. Stockfish is strong because it is especially strong in both areas. But a good eval is very important.

Re: Andscacs nnue 0.1

Do not get me wrong. It is a lot of work to write LC0. It is a lot of work to graft NNUE onto SF. It is a lot of work to run a million trials to make a net. It is just that there is no originality in it whatsoever. That is just how neural nets work. The net acts intelligently, but "how" it does it ...

Re: Are Free Antivirus any good for your Computer?

Windows Defender is bundled with Windows now. That is probably all you need.
