Re: Winter is Coming (Amoeba, Beef, Combusk, Demoli, Fab, Halogen, Koivi, Lc0, Marvin, Minic, Nemori, Orion, Pedone, Win

Thank you for the tournament! Indeed luck for sure plays a big part in 58 rounds. From the rating lists we know the two Winters are closer to about 100 Elo separation whereas here the performance differs by about 170. I quite enjoyed following the classic old-school large double round robin format. ...

Re: Chess programs :: Source available, but not today?

This is an interesting problem. My intuition would be that if they are open source it should be fine to rehost them. That being said if the source is deliberately being taken down by the program author (eg because they don't want to have a github account), the ethical situation is less clear. For th...

Re: Winter 0.9 64-bit Gauntlet for CCRL 40/15

Thank you for testing!

I usually had the games open in the background and followed a decent few interesting ones :)

That was a fantastic game! Perhaps a bit too adventurous by Winter indeed, but also well defended by Fab.

Thanks for including Winter in your tournament!

Re: Mayhem NNUE - New NN engine

This proves that handcrafted evaluations are all crap. This will cause enough heads here to shake that it'll cause an earthquake. :lol: Maybe a better way to express yourself is "this proves that copy and pasting Stockfish's evaluation into other engines is superior to using your own". Something we...

Re: Centipawns vs Millipawns with NNUE

I would be surprised if many engines are actually using centipawns as their most finegrained score internally. With regards to centipawn output I think it was also just a nice interpretable way for users to be able to understand engine output. I will note that having more coarse grained values has b...

Re: New engine releases 2020

Seer 1.0 I've spent a good chunk of my free time this summer writing a chess engine in C++ which can be found here: https://github.com/connormcmonigle/seer-nnue/releases/tag/v1.0. It should, hopefully, play at around 2900-3000 elo if AVX2 extensions are available (around 300-400 knps should be expe...

Re: 87% of the poll voted that SF will win Tcec Sufi 19.

It has been clear for sometime now that the unbalanced book is very unfair to Lc0. TCEC does it for the sake of entertainment, but drawing any conclusions from it doesn't make any sense. This SuFi and last one have been all about who can convert better given a position with a +1 advantage. If every...

Re: 87% of the poll voted that SF will win Tcec Sufi 19.

I do think Daniel Shawul has a point. One might argue (and, indeed, I have) that since both sides must play the exact same lopsided opening from the disadvantaged and advantaged point of view it should be a wash. If I have a dominant position and win, next time, the opponent has the same dominant p...
