Fat Fritz 2

[carldaman]

Why not just upgrade the old Fat Fritz 1.0 engine with this network .. Or bringa a truly unique engine to the table as Fat Fritz, instead of just ripping of the best Open Source one...

They certainly had Fritz 17 which I assume they could have modified and enhanced to use their new CPU based NNUE.

I'd thought they'd go that route, too, but then it wasn't likely they would end up with a "new #1" (ahem)...

[Graham Banks]

Or another way to put it..

Why is
Crystal,
CFish
Fisherov
RaubFish
Eman
Sugar AI
Corchess

etc.. exluded on the list..

One needs to set a limit. I've chosen to test ShashChess and SugaR, and stay away from the others.
Plenty of other engines to test.

That has to be one of the most "human" games I have seen played by top engines!

ChessBase doesn't have to do anything anymore. Every 3 months they take the current Stockfish dev. Version, makes update to a Fat Fritz 2.x and claim Fat Fritz 2.x (and not Stockfish) got 15 Elo better! Great prospects at the expense of the Stockfish developers.

+1

They could at least donate some CPU hours to Fishtest, or alike.

[Gabor Szots]

it is a bad choice to include Fat Fritz 2 on the list

I don't think so. It is of great public interest, therefore its inclusion is justified, IMO.

[Gabor Szots]

Or another way to put it..

Why is
Crystal,
CFish
Fisherov
RaubFish
Eman
Sugar AI
Corchess

etc.. exluded on the list..

Speaking for myself, I am not interested in them. I think that public interest is also quite limited.

You don't have a copy of the net either?

I don’t do Windows and most of the chessbase software is Windows based. (I may have an ancient copy of chessbase for Windows NT somewhere.) I’ve restricted my comments to the GPL as I can’t speak to how FF2 plays or whether it would be worth X $ to someone. I somehow assumed that you had a copy, given your confident statements about how strong or weak FF2 was.

No. I have the impression that nnue net files were just data files, similar to pdf files, jpg or bmp, those file types were
not built for specific OS and hence can be easily openned/ported on any OS platforms.

I just checked the files at https://tests.stockfishchess.org/nns too, but only 1 file for any types of OS, whether android, macOS, Linux or Win OS's.

edit,
Sorry for passing by, just a newbie programmer here and I have great respect for people like you who have
contributed to chess technologies and its advancement just like the 80% (maybe more) of members here who were considered legends on this field too .

[Moderation] Please guys, don't get over-excited. This is perhaps an event with strong moral implications, but keep it civilized. No name calling. I had to remove a number of postings because of that.

[Modern Times]

CEGT have published their updated lists now, and have both Stockfish and Fat Fritz 2 on their "Best Versions" list. So they are treating them as separate entities as well.

Just to repost my test results which supports the idea that nets are more important than the engine:

The sim tests were done most recently by laskos (sp?) across a range of nnue and non nnue engines and posted in this forum.

My own test were with Toga III and SF at fixed depth across 20000 positions. At d12 with the same net, SF12 and Toga agreed on best move over 95% of the time. The 5% where they didn’t match looked to be imbalanced positions where hybrid (sf) or lazy (toga) kicked in, though I haven’t gotten back to this experiment to verify that hypothesis.

SF with the default net matched less than 50% of the time (42%?). I’m pretty sure a stronger net like Dark Horse would match more frequently with default SF.

The PV past the first move often didn’t match, though I didn’t gather stats on that. Below a pretty typical example from a Seer vs a0lite game.
