ChessBase is selling this Stockfish clone for €99.90. They have also disabled comments on all of their articles so far about Fat Fritz 2. Not a good look.

Thanks for the link. That git diff is absurd: 9 changed files with 21 additions and 30 deletions[1]. It really is just Stockfish using different weights and changing the name... The fact this Albert Silver fella did the same with Leela Chess Zero two years ago is even worse, no remorse!

They are a sketchy company, from the over-zealousness to defend their "IP" to the price they demand for their yearly software, to the creepy vibe their articles about young female players have. So no sympathy from me, go stockfish.

Im looking at the diff, they doubled the size of NN and added themselves as additional authors in addition to the original authors and released source when requested. I.e. they gave credit to original devs, I don't understand where they violated anything. NN weights is data not code.

Yes but read the article. It's the way the "author" presented the work as novel that's indefensibly hucksterish

Do you have any links for these things?

People are never just ONE type of awful. It's almost always a package deal.

It's also just an appalling piece of software. I wish the market for competitive chess were bigger so someone was incentivised to dethrone them.
