I'll probably do UCI_ShowWDL (default off)
This is probably the safest option for backward compatibility.
However, if it can be proved that almost all the GUIs will just ignore the additional wdl info, I think it would be best to not add any option at all.

if you used the proposed UCI_pvinfos option
Please, consider at least a minimum consistency.
All the options start with a capital letter and use the camel case:

Re: UCI Win/Draw/Loss reporting

So I'll just use that, defaulted on, and provide a (non UCI_ prefixed) option to disable it in case anyone ever runs into an "UCI" interface that breaks on it (which it shouldn't). The drawback of this approach is that the user will see an option which does nothing. Let's take a GUI which is not up...

Re: Fritz 17

I know it’s hard to climb down from the righteous indignation barricades (and god knows this forum doesn’t enjoy a good track record in this regard), but hopefully you’ll realize I’m just trying to provide information and clarification, not sharpen my own particular axe. My post was exactly in resp...

Ah, the misunderstood GPL.

Nothing that wasn't already known unfortunately.
tl;dr

Based on the ELO difference, the current algorithm gives the following probability of winning:
+0 --> 50%
+100 --> 64%
+200 --> 76%
+300 --> 85%
+400 --> 91%

What are values of the improved algorithm?

Re: PGN standard, its improvement and standardization

The main thing for me is to unify the formats of online tournaments That can be done with the current PGN. You already posted how TCEC encode the engine's evaluation: d=16, sd=51, mt=161000, tl=7049000, s=219832, n=35024512, pv=Nb3 ... But is the order of the operands mandatory? sd=51, d=16, ... is...

Re: PGN standard, its improvement and standardization

The PGN format is an abortion… But your proposals fail to adress the real problem of PGN which is its (un)parsability Some time ago I would have agreed, but then I rewrote the code for SCID and changed my mind. The trick is to avoid a state-machine that reads the characters one at a time: https://s...

Re: 29 Alpha-Beta's against Leela...

I organized a engines tournament; the A/B's got their best conditions, and the NN's got their best conditions. At the end I added up - basta :-) Great article, very interesting. To give every engine the best condition, I think it would be preferable to do two matches for each position, with inverte...

Re: Lc0 Settings

Is there a page explaining how the different engine Settings work (With minimum and maximum of values)? I found a page on the Leela homepage, but there are only parameters of Lc0 0.17. That's sad sorry. You can see all the options, along with their default, min and max values here. What they all me...
