https://github.com/ChrisWhittington/Chess-Openings-DataSuitable for testers. Lines are active, usually with both sides having active play/counterplay. Selection criteria are highest non-draw result rate (W+L)/(W+D+L) from a large set of chess rating list computer-computer games. The idea being that no matter what the static evaluation of a line is, the important detail is the engine-engine result after playing the line. White bias is shown for each PGN, ideally we would like whitebias=0.5, but it is usually greater. Lines with whitebias > 0.7 are culled.
In practical play between strong engines I don't vouch for a much reduced draw rate, but I think you'll find the games are much more unbalanced in a play-counterplay sense. What an engine pair makes of that is up to the engine pair.
These PGNs:
require at least 50 examples each
are ranked on non-draw rate
use a whitebias filter of 0.7
use an eval filter of 200 (SF15 analysis at 1 core and 1 second)
are 11 ply deep
