Where can I download the Fat Fritz 2 network? I don't see it on the github.

I see. Just wanted to add that if I try to build a large net like this I won't let classical eval to interrupt it. To be more effective, larger evals must be pure.
If there is only one file and that is binary, dkappe, everything is code. Or this means I can rename it, name myself as an author right next to a general authors word and sell it by just adding one more eval term.

Are you asking or telling?

The net and engine might be covered by different licenses, as is the case with Stockfish (GPLv3) and the stockfish networks (creative commons).

I’m in the process of training up a compatible version of Frosty. Let me know where I should mail the DVD when I’m done.

It's always a good idea to actually check the license of the software you're selling.

That said, given that this link still exists: https://shop.chessbase.com/en/products/ ... or_version,
the idea of enforcing the license of Stockfish is obviously 100% a laughing matter, with that I can't disagree.

And it’s always a good idea to actually check to whom you are responding.

Shall I send it to you as cuneiform tablets?

I see the Shop page says it is from Albert Silver, the comment above made it seem as if you were involved. But I understand now you were just trolling, got it.

Nope. I’ve certainly helped with some scripts and advice, but I do all of my chess development and net training for free. If I were to sell my work, however, then I would be a thief and a terrible person. The GPL is not anti business or anti profit. Quite the opposite. It just seems that in chess circles, profit is viewed as evil.

Commercial version of SF? I smell SF dev here .

Wish it was a Fritz 17 add-on like FF1, $150 seems a bit steep. Curious to see results.

If there are any changes they do have to release the Fat Fritz 2 source, but if its like Fat Fritz 1 then the changes seemed mostly cosmetic.

I do not know the legality of the nets though if they generated their own, I think technically they can sell it as a separate product. It's copyrightable data, like an egtb.

Rybka, Houdini and now this one!
The question is:
Should I delete the links to Chessbase from the webpage?

Other products are really good (example: Chessbase database).

Possibly. At least add a message publicising what Chessbase has done here.
