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

I think chess engines have become so much stronger than humans that ELO breaks down when trying to measure by how much. The trick is to reduce the speed (or the time) use by the engine. 40 real games (90min+30sec) by a slow Stockfish 11 (around 10 kilonodes/second or 1/100 the time on an average sm...

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

Surpassing Deep Blue's 200 Million nps. But 22 years later... But now, Stockfish at 1 Mn/s is stronger than Deep Blue at 200 Mn/s. 8-) Stockfish at 1 kn/s is stronger than Deep Blue. Is it? I’m not sure that’s right Stockfish should be GM level even at 100 n/s classical time control. Probably 0.5 k...

Smoothing SF progress of nextchessmove

I like to look at https://nextchessmove.com/dev-builds where you can find 20000 test games of the latest SF builds. But the curve still irregular, so I made a smoothing in Excel : for each version I took the average of the 10 previous ratings. (+ a linear regression inside Excel on the dash line). T...

I recently came across my old M-Chess Pro 7 (Copyright 1997) cd. Does anyone know of a way to run it on a new computer with Windows 10? Thanks! DosBox?.........Its worth a try... :) :wink: Yes, DosBox allows to run a lot of old softwares. You can use "D-Fend Reloaded" to configure the parameters au...

WAC-300 is known to be busted
No, it is not busted. g6 is the clear-cut best answer.
I think he means : "the WAC (300 positions)".

Re: First knight odds match with IM Saturday

... I think it should be a GM with a current FIDE rating (including recent games) over 2500, the normally required rating to get the title (except for winners of World Championships in their categories). With these conditions specified, I hope we can do it sometime this year, although it might not ...

Re: win at chess #223

Stockfish thinks the 4 best moves are very close (around -2): FEN: r1bqk2r/pp3ppp/5n2/8/1b1npB2/2N5/PP1Q2PP/1K2RBNR w kq - 0 1 Stockfish_19121008_x64_modern: ... 25/40 00:25 209 425 536 8 266 906 -2,52 1.Be3 Nf5 2.Qxd8+ Kxd8 3.Bf4 Bxc3 4.bxc3 Re8 5.Ne2 Bd7 6.g4 Nxg4 7.Rg1 Nf2 8.Nd4 g6 9.Nxf5 Bxf5 10...

Re: First knight odds match with IM Saturday

I think we'll start with g1 off, then b1, repeating, so: rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKB1R w KQkq - 0 1 rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/R1BQKBNR w KQkq - 0 1 rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKB1R w KQkq - 0 1 rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/R1BQKBNR w KQkq - 0 1 If Komodo wins...

Re: SPCC: Testrun of Lc0 LS 12.2 finished

Now You are testing 25.12. SF. But there is only one patch with Elo +0.41. Better to wait? On NCM there is a +5 Elo jump... :wink: NCM has a ±4 error. Indeed Stefan Pohl : "Latest Website-News (2020/01/04): AB-testrun of Stockfish 191225 finished. -4 Elo to Stockfish 191210." The rating at https://...
