SPCC: Testrun of Fat Fritz 2 github finished

[pohl4711]

AB-testrun of SF Fat Fritz 2 github finished.
Vondele (Stockfish team) made an avx2-compile of Fat Fritz 2 source code from github for me. I downloaded the free version of the FF2-net from GitHub. This is the freeware/GitHub version of Fat Fritz 2. Same conditions as in my testrun of Fat Fritz 2 commercial version. 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.

Fat Fritz 2 github has a suprisingly strong result in my testrun, compared to Fat Fritz 2 commercial. Of course, the github-version is weaker, but the difference is smaller as I expected.

Hi!
Can you please share the Github GPL 3.0 Fat Fritz 2.0 NOT COMMERCIAL Vondele version?
So more tests can be done by indipendent chess players

Thank you!

It is an avx2-binary. It works properly only with AMD Ryzen oder Threadripper CPUs.
