Didn't even need 25 million nodes to find it.
Absolutely incredible.

i think ive seen the future of SF now, thx very much for sharing Raph !
look eg what it does with this position:
[d]4q1kr/p6p/1prQPppB/4n3/4P3/2P5/PP2B2P/R5K1 w - - 0 1
bm Qxe5
it says completely winning after just a couple of seconds...

or with this position:
[d]rnb2rk1/1pq1bppp/p3p3/2npP1P1/3N1P2/2NBB3/PPP4P/R2QK2R w KQ - 0 1
bm Bxh7
stunning, solved within a minute or so !

and im quite sure that this is just the beginning as well, hf, stay patient

Yes, amazing. The first is solved in seconds. The latter is solved in less than a second:

hi Louis, hi Mike
very interesting times hehe...this projekt seems also very strong with fortresses at first glance...although i observe that "pure" SF is here and there significantly faster (on my old APU-machine) in various positions, NNue shines bright, for example 2 fortress-testpositions we all know about:
Brzozka-Bronstein, 1963:
[d]1r6/4k3/r2p2p1/2pR1p1p/2P1pP1P/pPK1P1P1/P7/1B6 b - - 0 1
bm Rxb3
a matter of seconds for NNue !

or this one:
[d]3B4/1r2p3/r2p1p2/bkp1P1p1/1p1P1PPp/p1P1K2P/PPB5/8 w - - 0 1
bm Ba4
i dont know if it needs milli- or microseconds for this
ok, it doesnt show 0.00 but sth like -7.5 but it solves it !

Ah, ok. Thanks. Bit tricky on a iPhone in that format, can’t actually see half the move list and so on.
Well, apart from beating the mighty god Stockfish, this wasn’t a particularly fascinating game. You may consider it win at move 15, but it still took until plycount 100 to grind it out into an ending, and as for the other games, draws with huge ply counts.

So contrary to Chris’s statistics with Laskos own set of 100 games and MikeB set of 1000 games, indicating very long tedious games with high ply counts and zero fireworks, you have one anecdote (in six tediums). Ding dong, round two. So far, not impressive, apart from the results of course, although there’s not really enough of those either, bean counter versus net trained on bean counter, all very efficient and mechanical, but, at risk of activating TC, I would say this is not really chess in the sense that AZ, also Leela, have shown.

Twenty more games between Stockfish-nnue and Stockfish-dev. Three wins by Stockfish-nnue, none by Stockfish-dev. 20 threads, 4 GB Hash, 6-man tables:

Well, if you want "exciting" games (i.e., games full of errors), there are many human "masterpieces" to study.

it did shine, I only see Bluefish Xir4 now getting this in less than a minute, your mileage may vay

As it may well be with many positions, that could be solved with SF NNUE (almost as well or even better then with LC0) before the mystery- patch called NNUE-treshold-eval or mixed evalutation or hybrid eval, started switching off the use of nets trained with much hardware- time of their own but then just don't get used by the engine even without any chance for the user to see the difference other then in output.
For nothing else then 11 Elo in STC and selfplay.
