Re: For data lovers only

That might have been true at some point in the passed, but nowadays the distributions match fairly closely in that rating range. 2200 Lichess blitz is roughly 2200 chess.com blitz. When analyzing the quality of the moves people play, it seems chess.com's 1300 elo players play at the same level as 1...

All done...

In total 25.6 million annotated Stockfish games.

Say average game length is 60 moves, we get:

25.000.000 x 120 = 3.000.000.000 positions

for NN training or other purposes.
Are they SF games (... against SF?) annotated by SF or are they just arbitrary games annotated by SF?

Re: For data lovers only

So far I have 3.7 million human-human games between at least 2200 elo rated players. Why was 2200 elo chosen as the cutting point? I believe it's equivalent to 1900 elo of chess.com. That might have been true at some point in the passed, but nowadays the distributions match fairly closely in that r...

Re: Leela Chess Zero 42703 vs Stockfish 010719 CCRL(f) = 28h/40

Are you saying you are getting 42x single threaded speedup over single threaded performance of the Athlon when running a 32bit program like the Crafty Benchmark? Because a quick google search makes me think it should be more like 3x. https://www.cpubenchmark.net/cpu.php?cpu=AMD+Athlon+64+X2+Dual+Cor...

Re: Swiss Tournament Ed.VIII. Group A.

After a slow start Winter finally won a game. It did it in the best way possible though, a win with black against one of the most important (historically) and well known engines, in a nice attacking style.

Re: CCRL scaling versus human player

I feel it is conservative to estimate 2800 CCRL at only 2800 FIDE. That being said there are a lot of factors that complicate matters. Humans memorize openings, this means they will play far stronger than their ratings in the opening, until they are out of book. I don't know if the context you are t...

Re: ChessBase's prophecy of 2004 fulfilled in 2019

Seems like a fun experiment. I do sometimes wonder how people would react if we teleported modern engines back in time. Potentially even further back, though before the 2000s you might have to send hardware back as well. Especially since people of the passed would have no idea how to actually play a...

Re: Question for Nelson Hernandez - TCEC power consumption

The power draw from the TCEC GPU machine will almost certainly be higher than from the CPU machine, but I don't know by how much exactly.

Are you asking out of general curiosity or is there something specific you are interested in?
