Re: Fat Fritz 2 Post by connor_mcmonigle » Fri Feb 12, 2021
It would appear ChessBase came to their senses and are now providing the entirety of the source (including the network) here https://github.com/DanielUranga/Stockfish/tree/ff2 . The FatFritz2 network can be downloaded here: https://github.com/DanielUranga/Stockfish/blob/ff2/src/FatFritz2_v1.bin . Following this change, there is now no GPL license violation in my understanding. ChessBase's marketing is still appalling, but such is life."

Just a little pre-test on my old machine.

1 Stockfish_21021123_x64 10.5/20  101==========1===0==  +3 -2 =15
2 Stockfish-FF2_x64       9.5/20  010==========0===1==  +2 -3 =15

20 games, white +4 -1 =15  {Both with their included nets; both slow on my x64 limit.}


Whtie won both in the first opening, D06 1.d4 d5 2.c4 Bf5 3.Qb3 e5.
The other openings saw both draws except the following:

" Latest Website-News (2021/02/16): AB-testrun of SF Fat Fritz 2 github finished: -39 Elo to SF Fat Fritz 2 commercial. I renamed Fat Fritz 2 to "SF Fat Fritz 2", to clarify, that the binary of Fat Fritz 2 is 100% Stockfishcode, except the modifications needed to use the bigger FF2-nnue net. What makes FF2 unique, is the (bigger) nnue-net built with FF1 (=Lc0) evals, that is a very interesting approach IMHO. ...

...Hopefully this explains why I think ChessBase's selling the executable
[also on GitHub] and weights [sold] separately doesn't violate Stockfish's license, while their selling the integrated binary was/is a violation.
"Or, are you under the assumption that the publicly available NN is equivalent to the embedded one that CB is selling?"
No.


Yes, it looks like the free NN net https://github.com/DanielUranga/Stockfish/tree/ff2
is weaker than the one purchasable and CCRL/CEGT rated. :sad: But we will see this soon:

https://www.sp-cc.de/
Latest Website-News (2021/02/14): ... This is the freeware/GitHub version of Fat Fritz 2. I started a 7000 games testrun. ... Result in 2-3 days. On my machine, Vondeles avx2-binary is around -7% slower, than the commercial FF2 avx2 binary. But that is no big deal, means an Elo-loss of (around) 3-4 Elo with my testing-conditions.
If anybody is interested in the benches: Bench of Fat Fritz 2 commercial (Contempt +24) is 4025201, bench of Fat Fritz 2 GitHub is 4511552 (Contempt +24 is default)
