Re: WDL

As many of know, NN engines have been reporting WDL data with Scoring Percentage for some time. A while back, I took their formula to convert to a centipawn and applied it the centipawn evaluation to come u It is worth noting that Stockfish's WDL is a function of both the evaluation and the current...

Re: Throwing out draws to calculate Elo

Dann what you are writing in this thread is frankly embarrassing. Draws play a role in LoS too. Implicit, but role never the less. If you play 10 games and have 5 decisive games for one opponent your LoS would be 97%. If you play 1000 games and have 5 decisive games for one opponent your LoS would b...

Re: TCEC Question

Much to my surprise LCO is really getting beat up. AB engines are not dead. Not even close. I do repeat my question : what about the LeelaRatio of the current TCEC configuration ? Maybe this is a clue to the match outcome... What is LeelaRatio? Imaginary number used by Leela fanboys. Give me a brea...

Re: TCEC Question

In less than 1000 games practically any outcome is possible amongst approximate equals. I guess that they are very close to equal, but SF had some fortunate outcomes. And if SF is stronger, it is not by an enormous margain, as evidenced by the draw count. I think the proverbial 'sample size' answer...

Just to throw some more fuel on the fire, the GPU server was rebooted after 26 games because admins thought there might be something amiss. Before reboot, SF +4. After reboot: SF +1. Who knows.
Before reboot, SF +4. After reboot: SF +4. Fanboys of NN usually don't know. :lol:

Re: Test position: Lc0 vs Stockfish, TCEC 18, game 65

Games like this are what make NN engines so fascinating! Stockfish-dev does find Qxb4, but it takes a long time. Note that the key move goes from last on the movelist to first: info depth 66 currmove f3h4 currmovenumber 50 info depth 66 currmove c4c8 currmovenumber 51 info depth 66 currmove c4b4 cu...

Re: Why do the latest Sergio Vieri 384x30b networks scale so badly?

Something looks suspicious in the tcec gpu utilization. Maybe. https://tcec-chess.com/gpu_temperature.txt It's taken every 5min, so when low, you look at one during SF move when GPU is idle. Lc0 fansboys are really starting to get paranoid. So hard to accept the fact that SF might have actually imp...

Re: Elo gain by core doubling - Komodo 14, Stockfish 11

That is nothing new, 40-50% extra nodes with HT is quite ok for Zen 2 architecture because comparing to Intel there is higher parallelization in integer ALU of each individual core. Would it be correct to assume based on this that turning hyperthreading on is more likely to be beneficial for chess ...

Re: TCEC Kibitzing

Dann's question was about kibitzing, not just watching.... I must admit that until now kibitzing and watching was the same for me. But it seems that (only) in chess kibitzing also means to make remarks about the game. This indeed needs an account. Learned something... Andreas Hehe, chess etiquette ...
