They should consider make any new engine with polyglot book support.

Stockfish 13

Official release version of Stockfish 13

Bench: 3766422

-----

It is our pleasure to release Stockfish 13 to chess fans worldwide.
As usual, downloads are freely available at

https://stockfishchess.org

The Stockfish project builds on a thriving community of enthusiasts
who contribute their expertise, time, and resources to build a free
and open-source chess engine that is robust, widely available, and
very strong. We would like to thank them all!

The good news first: from now on, our users can expect more frequent
high-quality releases of Stockfish! Sadly, this decision has been
triggered by the start of sales of the Fat Fritz 2 engine by ChessBase,
which is a copy of a very recent development version of Stockfish
with minor modifications. We refer to our statement on Fat Fritz 2[1]
and a community blog[2] for further information.

This version of Stockfish is significantly stronger than any of its
predecessors. Stockfish 13 outperforms Stockfish 12 by at least
35 Elo[3]. When playing against a one-year-old Stockfish, it wins 60
times more game pairs than it loses[4]. This release features an NNUE
network retrained on billions of positions, much faster network
evaluation code, and significantly improved search heuristics, as
well as additional evaluation tweaks. In the course of its development,
this version has won the superfinals of the TCEC Season 19 and
TCEC Season 20.

Going forward, the Leela Chess Zero and Stockfish teams will join
forces to demonstrate our commitment to open source chess engines and
training tools, and open data. We are convinced that our free and
open-source chess engines serve the chess community very well.

Stay safe and enjoy chess!

The Stockfish team

It has been tested in a deep match of ten thousand games against the February 11 build of Stockfish, which has since become the new Stockfish 13. This match was played by an independent tester who used a fixed eight-move deep book that is taken from a base of 2.1 million games played on LiChess in 2020 by opponents both rated 2400+.

Code:


Official test by SF team, at fishtest conditions, of Stockfish 13 vs
the sold version of CB/AS (ff2) net and the corresponding Stockfish player.
===========================================================================

TC 10+0.1
=========

games at: https://drive.google.com/file/d/14TVxuyOGWAVc2kJyR6K7DEUOetZfWplm/view?usp=sharing

../ordo -a 0 -p out-sf13-vs-ff2-TC10+0.1.pgn -A sf13 -s 100 -q  -J -D -W

   # PLAYER    :  RATING  ERROR   POINTS  PLAYED   (%)  CFS(%)
   1 sf13      :     0.0   ----  34445.5   65536    53     100
   2 ff2       :   -18.1    1.3  31090.5   65536    47     ---

White advantage = 29.29 +/- 0.67
Draw rate (equal opponents) = 77.35 % +/- 0.18

TC 60+0.6
=========

games at: https://drive.google.com/file/d/10yOOoCqt12sssmKy3jSI7og-M-nNs_Xs/view?usp=sharing

../ordo -a 0 -p out-sf13-vs-ff2-TC60+0.6.pgn -A sf13 -s 100 -q  -J -D -W

   # PLAYER    :  RATING  ERROR   POINTS  PLAYED   (%)  CFS(%)
   1 sf13      :     0.0   ----  33774.0   65536    52     100
   2 ff2       :   -10.8    1.0  31762.0   65536    48     ---

White advantage = 24.72 +/- 0.50
Draw rate (equal opponents) = 87.77 % +/- 0.14

Conclusion
==========

The ff2 net is weaker than SF13 in a proper testing setup.
Draw rates are comparable to fishtest results.
Setup and parameters
====================

Same setup as fishtest, using 8moves_v3.pgn book, run in 128 batches (command used for TC60+0.6):

../cutechess-cli -repeat -rounds 1 -games 512 -tournament round-robin -srand $RANDOM -resign movecount=3 score=400 -draw movenumber=34 movecount=8 score=20\
                 -concurrency 64 -openings file=../8moves_v3.pgn format=pgn order=random plies=16\
                 -each tc=60+0.6 option.hash=64 proto=uci -ratinginterval 128\
                 -engine cmd=../stockfish.sf13 name=sf13 \
                 -engine cmd=../stockfish.ff2 name=ff2 \
                 -pgnout out-sf13-vs-ff2.pgn

Corresponding to SF13 and FF2 as available Feb 21st

../stockfish.ff2 bench 2>&1 | grep "Nodes searched"
Nodes searched  : 4025201

../stockfish.sf13 bench 2>&1 | grep "Nodes searched"
Nodes searched  : 3766422

Compiled using exactly the same compiler and same settings

on master at SF13 commit
make clean && make -j ARCH=x86-64-avx2 profile-build && mv ./stockfish ./stockfish.sf13

on ff2 branch with the CB/AS net added to the src directory
make clean && make -j ARCH=x86-64-avx2 profile-build && mv ./stockfish ./stockfish.ff2

It would be great to see a dedicated SF team put together a GUI that is on par with a Chessbase's.
This would eliminate their best/only competitive advantage and possibly nudge them toward eventual irrelevancy/bankruptcy.

That's a very good idea. SF and LC0 team should build a GUI :-)

Yes Yes Yes ! I am totally with something like that !

Why not test Fat Fritz 2 with Sugar AI 1.50?
