Fat Fritz 2

[Modern Times]

Someone has spent many hours working on something that has improved SF 12

Not even to the level of one month old SF dev:

Code: Select all

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 more games.

LOS is 82.8%. I'd be surprised if the tables were turned at this point, next week's update will tell, but Pohl's testing is similar and CCRL blitz places FF2 just barely ahead of SF12, so keep waiting.

Did you look at chess960 ?

Never, not my cup of tea.

Fair enough.

Please mention, that in my testrun, FF2 played with Contempt=+24 (default is 0), because I wanted a better comparability with my Stockfish-testruns (Stockfish has a default Contempt of +24) and because, I believe, that Contempt=0 will cost measureable Elo, if a really strong engine (like FF2 is) is tested vs. some weaker (and some much weaker) engines. So I expect measureable weaker results for FF2 in the CEGT for example.

So with default options, FF2 results would be worse?

Your argument, in my understanding, is that some third party might have licensed the parameters included in the binary ChessBase is distributing under a different, GPLv3 incompatible, license. Therefore, ChessBase is illegally distributing the binary. Furthermore, I, as the recipient of the GPLv3 licensed binary from ChessBase or those having indirectly received the binary from ChessBase, would be at fault, legally, were I to extract the parameters from the binary.

This doesn't make any sense for two reasons:

1.
In the above description of the situation, I would not be at fault as ChessBase would be responsible for all damages incurred on said third party as I, as the unsuspecting recipient, could have had no way of knowing that ChessBase illegally distributed the binary to me.

Yes, dkappe's grand claim that "you will go in prison" if you redistribute the FF2 binary (something you are entitled to because of the GPL license) is nonsensical because the only way this redistribution would violate someone's copyright is if ChessBase itself is violating copyright.

The risk of ChessBase engaging legal actions (slow, complicated, costly) are very low. The complications of the legal process are why ChessBase still dares to sell Houdini 6, they or Houdart haven't been sued over it. But furthermore, if they went to court, they would have very low chances of winning because facts are against them. They'd have to hope the judge is stupid.

There's some evidence of it:

But the effect is smaller than the margin of error.

Where did I make a grand claim that you would go to prison? A throwaway joke with a following LOL? Copyright violation is usually a civil matter, though the number of criminal prosecutions for piracy and willful copyright infringement has been on the rise. I doubt any prosecutor would bother.

As for your rights under the GPL, you need to go back to remedial class.
