Re: Stockfish 11 at 120k nodes per move

So this is basically some empirical evidence that my claim of SF at 100 n/s = GM level was right. With +-2400 being at the low end of GM level. People underestimate engines. Did you omit a zero? A thousand n/s is at least in the ballpark, a hundred is ridiculous. I have the Revelation chessboard wi...

Re: 237 Mn/s for Stockfish on an 2xEPYC 7742

Yes, SF hasn't become any stronger at 1s+0.01. This is particularly related to this patch : https://github.com/official-stockfish/Stockfish/pull/2260 It lost 40-50 elo at 2s+0.02 ; lost ~4 elo at 10s+0.1 @ 1.6mnps ; gained ~1 elo at 20s+0.2 ; gained ~5 elo at 60s+0.6 and around ~12 elo at 180s+1.8....

Re: 237 Mn/s for Stockfish on an 2xEPYC 7742

You'll be surprised just how strong SF is, even at low node counts. This is especially true with the latest version of SF. I think SF has gained incredible strength at low nodes thanks to tuning against Lc0! I've tested numerous SF versions on 1+0.01s on my i5-4460, i5-3470 and an i3-6100U and curr...

Re: 237 Mn/s for Stockfish on an 2xEPYC 7742

How far it is above Crafty really doesn't affect my comments. 2K nodes per second is not going to beat a GM. Might not beat a master, since most of the speculative pruning stuff really needs exceptional search depth to bypass the holes it causes. 1 second per move vs 180 seconds per move? Maybe. Bu...

Re: Syzygy on RAM Drive

SSD of course. I also play with 7 men. Runs well on SSD. HDD is not good enough. Yes HDD are awful, but if you are strapped for cash. I have even put Syzygy on a thumb drive and it works... HDDs aren't a cost-effective long term solution if you do a lot of analysis or do a lot of computer tournamen...

Re: Dylan Sharp Vs. Harvey Williamson (G4)

I obviously can't formally prove the game theoretic value. But regardless I am 99.8% sure it's a loss. That's basically what people were saying about 1.g4, and the reason this game is taking place. Once you're done with this game we could test the Bongcloud 1. e4 e5 2. Ke2. I'm confident enough tha...

Isn't Fat Fritz just renamed lc0? If so there's no benefit on making it use other weight files, just make Leela do it.
Chessbase has modified the executable too.
Nothing significant but it's a little more user friendly. (noob friendly)

Re: The Stockfish of shogi

Fairly sure her networks store chess piece values. Sure, but the value depends on the position, it'd be something like "this Bishop here is useless so it has some 0.80 value and this other Bishop is a killer so it's worth 6.00" , not like A/B's "all Bishops are 3.00 but this one is locked to lets s...

Re: The Stockfish of shogi

Definitely the Rook and Bishop value in mini-Shogi should be much smaller (using Gold as a standard :wink: ) than in regular Shogi. In mini-Shogi B and G have about the same value. I learned this the hard way, as I was too stupid to foresee it: when I participated with my Shogi engine in the comput...
