However, the net is not that strong in games, right? Or I am doing something wrong...
In a 200 game match on my PC it beat my 27-6 net, but not outside error margins.
I'll run a longer match soon.
Sorry, used wrong openings. Thanks!
Here's are six games between Stockfish-nnue (with Sergio's network) and Stockfish-dev. Stockfish-nnue scored the only win. Both engines used 20 threads and a 4 GB hash table.

Wow, nice win! Asymmetric evals and by move 15 quite decided. A bit contrary to Chris' observation :).
So, now I am on PC and able to look in a bit more detail.
Game 1. 250 plycount tedious draw.
Game 2. 108 plycount adjudicated draw.
Game 3. The anecdotal win. Still grinds out into 100 plycount and an ending.
Game 4. 134 plycount tedious endgame draw.
Game 5. Have mercy. 356 plycount zzzzzzz falling asleep.
Game 6. Mercifully end in draw, 126 plycount.

I make that a mean of 179 ply for a game. The only win took 100 ply.
This is not exciting chess. It's entirely mechanical, no style.

However, the net is not that strong in games, right? Or I am doing something wrong...
In a 200 game match on my PC it beat my 27-6 net, but not outside error margins.
I'll run a longer match soon.
Sorry, used wrong openings. Thanks!
Here's are six games between Stockfish-nnue (with Sergio's network) and Stockfish-dev. Stockfish-nnue scored the only win. Both engines used 20 threads and a 4 GB hash table.

Wow, nice win! Asymmetric evals and by move 15 quite decided. A bit contrary to Chris' observation :).
So, now I am on PC and able to look in a bit more detail.
Game 1. 250 plycount tedious draw.
Game 2. 108 plycount adjudicated draw.
Game 3. The anecdotal win. Still grinds out into 100 plycount and an ending.
Game 4. 134 plycount tedious endgame draw.
Game 5. Have mercy. 356 plycount zzzzzzz falling asleep.
Game 6. Mercifully end in draw, 126 plycount.

I make that a mean of 179 ply for a game. The only win took 100 ply.
This is not exciting chess. It's entirely mechanical, no style.
Still, from a points a view...on a modest CPU beats Lc0, being slightly trained (at least compared to Lc0).

However, the net is not that strong in games, right? Or I am doing something wrong...
In a 200 game match on my PC it beat my 27-6 net, but not outside error margins.
I'll run a longer match soon.
Sorry, used wrong openings. Thanks!
Here's are six games between Stockfish-nnue (with Sergio's network) and Stockfish-dev. Stockfish-nnue scored the only win. Both engines used 20 threads and a 4 GB hash table.

Wow, nice win! Asymmetric evals and by move 15 quite decided. A bit contrary to Chris' observation :).
So, now I am on PC and able to look in a bit more detail.
Game 1. 250 plycount tedious draw.
Game 2. 108 plycount adjudicated draw.
Game 3. The anecdotal win. Still grinds out into 100 plycount and an ending.
Game 4. 134 plycount tedious endgame draw.
Game 5. Have mercy. 356 plycount zzzzzzz falling asleep.
Game 6. Mercifully end in draw, 126 plycount.

I make that a mean of 179 ply for a game. The only win took 100 ply.
This is not exciting chess. It's entirely mechanical, no style.
Still, from a points a view...on a modest CPU beats Lc0, being slightly trained (at least compared to Lc0).
Maybe, but to what end?

However, the net is not that strong in games, right? Or I am doing something wrong...
In a 200 game match on my PC it beat my 27-6 net, but not outside error margins.
I'll run a longer match soon.
Sorry, used wrong openings. Thanks!
Here's are six games between Stockfish-nnue (with Sergio's network) and Stockfish-dev. Stockfish-nnue scored the only win. Both engines used 20 threads and a 4 GB hash table.

Wow, nice win! Asymmetric evals and by move 15 quite decided. A bit contrary to Chris' observation :).
So, now I am on PC and able to look in a bit more detail.
Game 1. 250 plycount tedious draw.
Game 2. 108 plycount adjudicated draw.
Game 3. The anecdotal win. Still grinds out into 100 plycount and an ending.
Game 4. 134 plycount tedious endgame draw.
Game 5. Have mercy. 356 plycount zzzzzzz falling asleep.
Game 6. Mercifully end in draw, 126 plycount.

I make that a mean of 179 ply for a game. The only win took 100 ply.
This is not exciting chess. It's entirely mechanical, no style.
Still, from a points a view...on a modest CPU beats Lc0, being slightly trained (at least compared to Lc0).
Maybe, but to what end?
Well, at least the SF testing framework should be satisfied :lol:.

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 ;-)

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:

However, the net is not that strong in games, right? Or I am doing something wrong...
In a 200 game match on my PC it beat my 27-6 net, but not outside error margins.
I'll run a longer match soon.
Sorry, used wrong openings. Thanks!
Here's are six games between Stockfish-nnue (with Sergio's network) and Stockfish-dev. Stockfish-nnue scored the only win. Both engines used 20 threads and a 4 GB hash table.

Wow, nice win! Asymmetric evals and by move 15 quite decided. A bit contrary to Chris' observation :).
So, now I am on PC and able to look in a bit more detail.
Game 1. 250 plycount tedious draw.
Game 2. 108 plycount adjudicated draw.
Game 3. The anecdotal win. Still grinds out into 100 plycount and an ending.
Game 4. 134 plycount tedious endgame draw.
Game 5. Have mercy. 356 plycount zzzzzzz falling asleep.
Game 6. Mercifully end in draw, 126 plycount.

I make that a mean of 179 ply for a game. The only win took 100 ply.
This is not exciting chess. It's entirely mechanical, no style.
Still, from a points a view...on a modest CPU beats Lc0, being slightly trained (at least compared to Lc0).
Have you tested Lc0 vs NNUE yet?
My GPU is just a lousy r9 380 so I'm having a hard time trying to create a scenario that doesn't take too much time, is representative and achieves balanced results between Lc0 and SF_devmaster.

I tried with with your net several days ago.
My hardware is very GPU-favorable. GPU is RTX 2070 and CPU is 4 core i7. Old "Leela Ratio" is about 3. And still NNUE manages to hold its own at short TC against Lc0.
At short TC (15''+0.25'') Lc0 with 1541 20b net or with 3010 30b net is about equal to SF NNUE GK. maybe just a bit stronger. That's pretty remarkable, as SF_dev loses heavily in these GPU-CPU conditions to Lc0.

Thanks, I was a little concerned it was good at beating SF and nothing more.
But if it's holding its own on 4 cores then that's great.
