Great work from you and all the other authors! Especially great thanks to nodchip for this great gift of NNUE to the SF community! This is a big step forward for SF and gives new opportunities to look for further improvements.

This is a great leap forward. We have seen great improvements in the past and this is one of those big ones. Congrats to all that have worked hard to make Stockfish an even more impressive engine than it already was.

This new dev is totally confusing (
NNUE evaluation threshold). When you select "Use NNUE", does that mean NNUE is used all the time or is it just
used when the position is even? In other words, is the default "use nnue when the position is even" and selecting "Use NNUE" makes it use NNUE all the time?
Otherwise how do you know what it's using? Certainly can't tell from the output.

Congratulations! Seeing a +90 elo patch that replaces the entire eval seems almost unreal. Really amazing work from everyone in the community, across NNUE inventors, SF devs, and fishtest devs :).

Rob: when you select ''USE NNUE'' it means that the engine always will use the ''NN evals'' (opening, middle game, endgames) from the net you have added.
Also, when the engine is using ''NNUE'', its KN/s will be MUCH lower, but the compensation is impressive. Those NN's evaluations are much better!
GREAT WORK. Congratulations Stockfish Team!!!

This is not anymore correct. After this patch
https://github.com/official-stockfish/Stockfish/pull/2916 which was commited yesterday.
If Use NNUE = false NNUE is never used. If Use NNUE = true the NNUE eval is used if the material imbalance (including pawns) is not more than around 2.5 pawns else the classic eval. For greate material imbalance the double speed of classic eval outweights to more accurate NNUE eval. Probably in such clear cases subtile positional factors plays only a minor role.

Thanks Stefan, good explanation.
You're right, I was not taking the very last patch into account. What exciting times in computer chess!

Well, the directions for using it aren't clearly spelled out in one place and the
parts are hard to find for new users, but it definitely is amazing. I've never
seen SF win the black side of the 3...Qd6 Scandinavian, but here the latest NNUE wins both sides.
