Re: Black moves first ...

Actually black moves first is being seen as an anti-racist idea, based on the assumption chess promotes white privilege (white moves first).

Nutty if you ask me...

Next-Gen GPUs for LC0

Concerning speedup for Lc0: With Nvidia Ampere on its way pretty soon I've been looking into leaked and (take with a pinch of salt etc etc) early reports suggest actually it's nothing special. Performance per watt looks surprisingly similar to Turing, with the new cards sucking 350W each rather than...

Re: MCTS vs Alpha-beta

With Lc0 a lot of the attention went on the NN and how it was better than a hand-crafted Evaluation Function. But I'm trying to understand the search side of things. I have a basic, layman's, working knowledge of alpha-beta search in chess and virtually no real understanding of MCTS, which I think ...

Re: Stockfish NNUE Questions

Hello All, Question #1 : In an earlier thread today, a member wrote that Stockfish NNUE switches to classical Stockfish (SF) when the evaluation exceeds 2.50. I wondered where that threshold was, so thank you! Regardless, alpha-beta engines are superior in endgames while NN engines have performed p...

In general the greater net of Leela give more exact evaluation than the small net of NNUE, I think.
Yes I was thinking this. And Lc0 may move to a bigger net one day too.

How deeply does the Lc0 MCTS search look ahead? It's not complete games is it?

Re: SF+NNUE 16 cores aganst Stockfish-dev 16 cores and Leela

If this score holds then things look like SF will be ahead even on 8 core against 2 x 2080Ti Lc0. Not sure if your network is the strongest network for SF NN but things are progressing so fast that in 2 to 4 weeks there will probably be some fast gains for SF NN and then things will stabilize. By t...

Re: Progress of Stockfish in 6 days

Is it now totally clear cut that SF NNUE is stronger than Lc0?

If Lc0 had 2x2080 Ti (say) what hardware would SF NNUE need to equal it?
