Fat Fritz destroyed Stockfish!

Post by George Tsavdaris »

Surely a nonsense title, but still its performance in this match was spectacular. :D
Of course too few games to conclude anything about their strength, but still Fat Fritz seems extremely strong!

Conditions:
Time control 1 minute + 1 second/move.
TCEC's Season 16 superfinal openings(50 so 100 games).
Stockfish dev (14 November 2019) with 30 cores on a Threadripper 2990WX 32cores/64 threads at 3.1 GHz.
Fat Fritz v266 with RTX 2080+2060 and 2 threads of the above 2990WX.
FatFritz(FF) was getting some 45 kN/s and Stockfish(SF) some 38 MN/s.
Full 3,4,5,6 and some 7 men syzygy TBs on NVME M.2 SSD.
I have chosen 30 cores for SF in order to get the same nodes per second ratio of SF/FF compared to TCEC so the performances could be similar to TCEC's.

Result:
FatFritz_v266 - Stockfish_141119, +19 -15 =66, 52.0-48.0, +14±40 Elo, LOS=75.4 %



In fact Chessbase with its 2 articles boycotted itself in promoting Fat Fritz! :D
As in the matches of the Chessbase articles, SF was having 16 000 000 N/s while FF 11 000 N/s.
If you compare this SF/FF N/s ratio is about 1.69 times bigger than what TCEC has for SF/T40_Leela so for SF/FF also(as T40's and FF's speed is similar as they use the same binary and nets are both 20x256).
So they gave a very big advantage to Stockfish over Fat Fritz compared to TCEC that they probably wanted to compare.

That is bad advertisement! :mrgreen: They showed just +15 Elo performance of FF over SF-10 while by using a more comparable N/s ratio closer to TCEC, its difference would be even +50 Elo or more.
E.g just by using fp16 for FF in the Leela's Lc0 binary they would get a x3 N/s so some 40-60 Elo more.

A moment from the match where SF's +2.12 for many moves was dead wrong and game ended a draw. Fat Fritz was correct on that.

Then lc0 would have also destroyed Stockfish !
Played my first Game today against a Fat Fritz user on PlayChess.
It was a boring Draw, that too with the Black pieces.
In fact, the Score was slightly in lc0's favour throughout the Match, though not enough for a win.
Fat Fritz refused to give me a Return Match, so I can't say what lc0 would have done with White.

I see no reason to buy Fat Fritz 17 when the free lc0 is serving me so well and that too with many more options of NeuralNetworks.

Here is another game where my lc0 literally FRIED the Brains of the much-vaunted Brainfish.

I was using the James Horsfall Thomas (jhorthos) NN, the famous J13B.2-188.

George Tsavdaris: considering the TC is 1 minute + 1 second increment, it can good choise to run with ponder enabled.

29 CPU for Stockfish and 2 for Leela and 1 for OS as buffer.

Using permanent brain with high-end chip for CPU vs GPU make more sense than AB vs AB. AB vs NN with ponder enabled do make more sense though.

Is this your test, George, or was it reported somewhere else?
