Ovyron,
Does that mean that you usually use whatever is the latest (non-experimental) net from Sergio?
No.
There's a very important factor on here: I'm playing against people that are using NNUE nets on faster hardware. Using the same net as them is just suicide, because they're seeing everything I can see, and then more by reaching deeper (it is obvious as we'll show similar evals for the whole game without disagreement, and I'll get cracked by the outsearch).
To beat them I've needed to use a different net than them. Despite them being around the same elo, they can have radical disagreements in their evaluation of positions (mainly, if a given out-of-book position is favorable for black, or for white.) If my net is better than their net at the opening position reached, they're doomed, and their hardware advantage doesn't matter.
Interestingly, for this both nets can be wrong, I just need mine to be less wrong than theirs. Say, in reality black has the advantage, but both nets say white has it. As long as I'm black I'll win, so I've needed to use extreme score fudging for my backsolved scores (say, an opening position where their net says 0.30, my net says 0.40, but I have it as -0.11 because black is better), causing really huge swings in scores (the french is currently on top
- e4 is winning the war against d4. The Scandinavian shortly appeared as best
- the opening position has jumped to a 0.18 score... tomorrow things can look extremely different. For comparison, from 2018 to mid-2019 e4, d4, Nf3 and c4 were tied at 0.00, and it took them year and a half to budge, now they're jumping all around the place.) This has become opening exploration with whatever net they chose.
But the path to success is clear: use the rarest net (one nobody else is using), make the book reach the positions where this net is right, and the others wrong. Easier said than done, but in Stockfish-dev times I didn't have a hope like this, nor was I able to clearly defeat these guys, and since they're some 100 elo stronger than they were before, beating them means something.
