Would it be possible to let LC0 use the full 7 piece tablebases to do 7 piece rescaling in training?

Saw this post last night and decided to try, I don't have a six core system. I have a quad core box with hyperthreading. I used the -75 comtempt with Stockfish 11BMI vs LC0 63426 using 1 RTX2070 Super. I ran a 40 game test which finished this morning. Time control was 4'2 Blitz, Stockfish 11 using ...

Some notes: 1,40 games are too few to measure Elo. 2,Basically the contempt has effect on the style of an engine and it has smaller effect on Elo. 3,The chess power of Leela strongly depends on the used net and the parameters of Leela together with move time. 4,In general against a dual RTX 2080 Ti...

Why on earth did you limit SF to 3 cores?? As pointed out by everyone, it can only be surmised that negative contempt is implemented very well. The strength difference is massive. As for SF winning TCEC with such settings...you can’t win if you don’t...win. He might only have a quad core or he was ...

Maybe I'm misunderstanding something here, but what you're saying is: You have a setup in which SF is clearly weaker than its opponent In this setup, negative contempt yields better match results than positive contempt But this is precisely what lowering contempt is supposed to do in this situation...

Its worth a try. Its good to experiment.

Yes I think the same.
We need even more different -contempt tests.

And also to have the option to display always contempt 0 in the evaluation, while using contempt -75, would be interesting. I like this idea. Or more general, show the "default settings" evaluation, when you modify the settings. Sounds much better. Can you write in on Github please. https://github....
