Re: TCEC S15, END of an ERA event is much more Brutal than I thought!

Lc0 has improved on many of the weaknesses it had and is playing quite solid ... only problem seems that time management can be improved. Hard to understand why obvious and only move captures can take many minutes to play. I was watching online one of the games where Lc0 played an incredibly effecti...

Re: Can Leela use 2x RTX gpus?

Without really understanding what is going on with the GPU or how it works in multiple configurations. Is it possible that the way things are setup now is giving a false positive? Maybe the higher NPS numbers are not actually giving the proper scaling due to some inefficiency in another sector? Some...

Re: Bluefish vs Leela in TCEC , who will win? BF =170 Threads, Lc0 =2x GPU

Are you serious ???? Aesthetic ???? Playing on for a 100 moves when a mate in 12 is there is not aesthetics! An engine is an analysis tool that is supposed to help us analyze a chess position so that we can train and learn from it. This really makes Lc0 useless to analyze as a stand alone engine an...

Re: Bluefish vs Leela in TCEC , who will win? BF =170 Threads, Lc0 =2x GPU

What on earth is going on in the second game that Lc0 won ???? I thought trolling play was fixed with the latest net???!!!! There must have been at least a 50 move shorter win! Also this under promoting thing has to get fixed ... really annoying to see an alien like strong engine play these silly m...

Re: A complete 2000 lines of code engine

I guess if anything ... this shows the importance of bug free code in a chess program. I think the first to show that was Fruit. While it is nice to have many features and many minor little tweaks to get the program to play "proper" chess ... bugs are the Achilles Heel of any chess program. Each add...

Re: Playing the endgame like a boss !!

The problem with that is that when you do not know how to convert 'certain wins', they suddenly become a lot less certain... Your statement also bypasses the fact that win probabilities as determined by the NN are not infinitely accurate, but are necessarily polluted by a great deal of noise. So in...

Re: Playing the endgame like a boss !!

The sad truth is that there are just way too many games like that with Lc0 and while in this case the end result was still a win for Lc0 … on many occasions there is a draw or even a loss, in what was a winning position. It is behaviour like this that makes Lc0 useless as a stand alone chess engine ...
