Re: FF2 verses SF, what are the important differences?

"Fat Fritz 2 is trained and developed using this NNUE technology, running inside the open source Stockfish binary, but with a completely new and different neural network that differs significantly from Stockfish's on a couple of key points: The first is that the evaluations and positions did not com...

Re: Fat Fritz 2

I looked into both nets with a HEX-editor and they are definitly different! How did you do that? The official release has no separate net, it's embedded. There is an updated version of FF2 (called update1) (source code on github), where the net is a separate file. Because the first release with the...

Re: Calling All Armchair GPL Lawyers

4) Yes, and they also need to clearly state that it is a stockfish derivate A.Silver told me, that the FF2 Binary is Stockfish 210111. Only changes are the modifications, which are needed to use the bigger FF2-nnue net. Since the update1 the Contempt was set to 24, again, which is default of all St...

Re: Fat Fritz 2

Personally, since the source and net have been published, I am somewhat neutral about it. Are you sure the net provided at the 11th of Feb 2021 at Github is the same net they sell? I would not put any money on it. And, apart from all the legal stuff discussion, Chessbase is selling nothing but a «M...

Re: SPCC: Testrun of Fat Fritz 2 finished

Here the single results of FF2 and Stockfish 210131 (latest SF DEV testrun in my ratinglist). Same conditions, same opponents, both with Contempt=+24. Because FF2 uses a net with double size of normal SF nnue-nets, the nps of FF2 are somewhat lower. On my AMD Ryzen 12core CPU I got these nps for the...

Re: Fat Fritz 2

Someone has spent many hours working on something that has improved SF 12 Not even to the level of one month old SF dev: 1 Stockfish 2021-01-11 64-bit 3537 +25 −24 80.5% −227.5 38.0% 668 2 Fat Fritz 2 64-bit 3520 +27 −26 76.8% −189.8 44.8% 520 Error margins. That may or may not be the position with...

Re: Fat Fritz 2

AB-testrun of Fat Fritz 2 finished. FF2 has a default Contempt of 0, what I believe is not good for ratinglist-testruns (FF2 is very strong and plays versus weaker opponents in a ratinglist-testrun). Because FF2 is a Stockfish-binary (only the nnue-net is different) and Stockfish has a default Conte...
