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

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"

Compiled using exactly the same compiler and same settings

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 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+.![]()
