Sergio Vieri second net is out

[M ANSARI]

Never mind wrong score read. Is there a working version of this engine that we can try out on Fritz 14 GUI where it works properly without any editing?

Thanks

Its getting scary!!

I ran 2344 vs 2141 overnight. TC: 3m+2s, 92 threads.

Score of StockfishNNUE 2344 vs StockfishNNUE 20200722-2141: 14 - 5 - 33 [0.587]

Elo difference: 60.7 +/- 56.8, LOS: 98.1 %, DrawRatio: 63.5 %
52 of 100 games finished.

Too few games to say anything with high confidence. Not even clear that 2344 is stronger than 2141, cherry picked LOS of 98% doesn't qualify as a stopping rule. 99.9% or higher are needed when cherry picking to have some confidence in superiority, and even higher for small number of games.

There are indeed too few games, however, some things indicate that this is a bit more than just statistical noise. First, draw ratio is relatively high and second 3m+2s on 92 threads is equivalent to LTC on a single thread so games quality must be quite high and subsequently noise lower than your typical test games.

I don't understand the noise other than statistical noise. Statistically, LTC and STC are the same, and there is no any quantification (estimation) of variance due to say "STC noise".

That's only because noise model we typically use in chess is just a crude (coin toss) approximation (just w/d/l and number of games) of real sources of noise.
Go ahead and run an experiment with 100 times 100 games match (of, in best case, 2 identical engines) at TC1 and 4xTC1 and plot Elo difference distribution (and calculate sigma of it) in both cases. You'd notice more difference in sigma than can be explained by just change of draw rate.

The reason might be higher correlation between paired side-reversed games in LTC. which in pentanomial model is counted as lower variance. I do observe that in LTC with unbalanced opening positions (side-reversed) I am using, and in this case the difference between LTC and STC can indeed amount to some 10% in variance. But if one is using balanced openings, the difference in variances is much smaller, as the correlations of paired games are smaller in general. One cannot say in general "LTC decreases the statistical variance", as statistical variances are additive.

Another quick test of 2344 against H6.03 using Nunn1 openings, G10s+0.2s - result +11 =8 -1.

Here is a crazy sacrifice by SFnnue on move 13. Of course - usual disclaimers and as Mike would say yomv and ymmv.

Can someone with good hardware test this one?

"My first little 256 network.. I tested it on Honey-XI-NN with pretty good result against stockfish-dev and Leela ... (d24 validation used, 6menTB)

This ribbit net is the same net as the much discussed 1134.

The wins continue for 2344 - this time against Ethereal +13 =7 -0.

This was a nice game against the French with a nice rook sacrifice.
