Arena frustrations

Can any of you tell me how to make it so Arena doesn't show the PGN list of games window every time a tournament starts? I see two options, and neither makes a difference. The options I try are under Options > Appearance > PGN: Close PGN-window when loading game, and Minimize PGN-window after loadin...

Re: Lc0 settings for Leela on GPU- Nvidia RTX 2080

Consider changing your CPUCT value for different time controls. 3.4 is good for bullet chess. 2.0 is good for TCEC controls (120’/40).

If you have “only” one video card, set threads to 2. More doesn’t help.

Re: How to find your Leela Ratio - for Windows users w/ GPU(s)

If you want to return to the dark ages of “hey, leela just beat stockfish on my computer,” be my guest. If you have a better benchmark, let’s see it. It’s easy to throw stones. Exactly. As an example, when I set my time controls to make the Leela Ratio 1:1, Stockfish and Leela were dead even after ...

Re: How to find your Leela Ratio - for Windows users w/ GPU(s)

... The so called effective "Leela Ratio" is different by a factor of 2 or more going from say 15''+0.25'' to 240''+4'', and maybe a factor of 3 or more compared to this "benchmark". The size of cache also matters... This is still useful benchmark to determine the general hardware configuration GPU...

For you, what is the best auxiliary engine ?
So far, Houdini 6 w/ "tactical mode=1" > Stockfishes. Haven't tried CFish, yet, but I'm going to soon.

Re: Is AlphaZero-LC0 (Leela0) A chess Engine?

When I used DKappe's LeelaRatio tool and adjusted my settings to get the ratio to 1.0 (1:1), the 100-game score was tied between Lc0 and Stockfish. When I ran the same engines with the same books and settings, w/o adjusting my ratio (which was 3.1, in favor of Leela), Leela "crushed" Stockfish by w...

Re: Is AlphaZero-LC0 (Leela0) A chess Engine?

... it is essential to establish a baseline that can be referred to. I.e. the NN is running in conditions better than Deep Mind offered AlphaZero, or worse. I meant it wasn't fair in regards to the hardware imbalance and the amount of "time" each engine had to think. I completely agree a common gro...

If you “only” have one GPU, the ideal thread count is 2.
