SF just got +40 ELO patch!

[Jouni]

Add a specific FRC correction from classical to NNUE:

Score of master vs patch: 993 - 2226 - 6781 [0.438] 10000
Which corresponds to approximately 40 Elo.

You should have mentioned in the thread title that this only holds for FRC.
(still nice of course)
For standard chess at STC it passes with +0.74.

Code: Select all

The patch passes non-regression testing for traditional chess (where it adds one branch).

passed STC:
https://tests.stockfishchess.org/tests/view/604fa2532433018de7a38b67
LLR: 2.95 (-2.94,2.94) {-1.25,0.25}
Total: 30560 W: 2701 L: 2636 D: 25223 Elo +0.74
Ptnml(0-2): 88, 2056, 10921, 2133, 82

Very nice. Stockfish 13 underperformed for me at chess960, I think I'll run a later version soon.

Running this now at chess960. Early days but looks good so far.

+6 ELO in FRC is NOT sufficient to beat Dragon in FRC, but it might draw the 50 games match in FRC4 TCEC Next year

Code: Select all

FRC SF 190321 vs Dragon  2021
                                   
1   Stockfish 190321 64-bit   +59  +78/=206/-26 58.39%  181.0/310
2   Dragon By Komodo 64-bit   -59  +26/=206/-78 41.61%  129.0/310

Mwyong test in youtube shows also +40 for FRC fix currently. Hard times for Dragon.

Elo difference between two chess engines is +54 elo in my test where an opening book is not used.

Elo development at FRC is realy impressive.

That is one heck of a patch !!

Yes single CPU blitz is the exact opposite of TCEC, but here Stockfish owns Dragon at FRC.

Of course, if this idea isn't already in Dragon then I guess it soon will be, courtesy of open source Stockfish.
