Re: AlphaZero to analyse “no-castling” match

Yep, can just start with no castling rights fen, or could disable in engine for a little more performance/efficiency.

The whole custom net business just reeks of opening book (biases) though. Thus I would expect A0 to offer better evals/moves for the first ~10 moves, after that well SF is SF...

Re: I declare that HCE is dead...

Yep, only exception I can think of is special case handling endgame / material key heuristics. General HCE - dead. I guess one could always try overlaying some stuff on top of the NN as well, but I imagine finding improvements there would be even more difficult than improving current HCE.

Re: will Tcec allow Stockfish with a Leela net to play?

Well, you could really unburden yourself by just probing Stockfish... Or by relying on a NN for eval. Real programmers program and that means hand coded eval to the moon. And I hope nobody is using null move pruning or alpha beta or min max or MCTS or LMR or singular extensions or LMP.... Original ...

Re: will Tcec allow Stockfish with a Leela net to play?

In my opinion, you've effectively killed half (the other half being the search) of what made your engine unique and interesting.
That is kind of the point of NNs though, to unburden oneself.

Re: Dark Mode

Indeed! Dark mode is great.

For eye strain in general, blue light blocking glasses work wonders. If don't have a pair already, snag some from eyebuydirect or zenni. Worth every penny.

Re: Can any engine solve this puzzle, White to move and Win?

How about you tell us?

Or rather, why should we care?

Or rather, why are your questions other people's responsibility?

Small progress scoring improvement. Numerous upstream patches to Stockfish. Release Page: https://gith...

Re: Stockfish classical going downhill now

What is happening is the superior NNUE eval allows for more aggressive search optimizations (narrower search) than what was/is optimal with only hand-coded eval.

Using classical eval still has the more aggressive pruning, which is not optimal for it.

Re: Crystal 3.0

Fwiw, I strongly recommend using a power of 2 for hash size. Others may or may not "work."
