Track the evaluation and PV of 1. g4, as well as the other four (historically) non-zero opening moves for white, on chessdb.cn (cdb).
The raw polling data (e.g. g4.poll
) are obtained with the help of the script
cdbpvpoll.py
from cdblib.
Note that the displayed evaluations in each case are for the position after the first
move by white was made, so (a) they are positive and (b) they will
in general differ slightly from the evaluation shown for the move in the start
position at chessdb.cn.
The polling data and plots are updated daily. In addition, we use
Stockfish's WDL evaluations
of cdb's PV leafs, and the positions 6 and 12 plies from the end of the PVs, to
monitor cdb's progress in exploring and evaluating 1. g4 (and the other four
moves). These evaluations are performed daily for the newly aquired polling
data, using e.g. the command stockfish bench 1024 16 30 g4.epd depth
for the new PV leafs in g4.poll
, and then stored in g4.wdl
.
The order of the data in g4.wdl
, and the associated PVs found by Stockfish
in g4_sfpvs.epd
,
g4m6_sfpvs.epd
and
g4m12_sfpvs.epd
, respectively,
corresponds to the order in g4.poll
.
