In SCID, it's quite easy to tune or set the opening weights for White for bin books. Can these be done for Black's openings? I don't see any option to tune or set the opening weights for Black's openings.
For example, I don't see e5, d5, Nf6, Nb6 or any reversed openings for Black in SCID's book tuning, under Tool. Why is everything tailored for White only, or I'm I missing something?
If not, does anyone know how I can get in touch with authors of the SCID or SCID vs PC GUIs, so I can suggest this option for tuning and setting opening-weights for Black openings to them? Thanks for any suggestions.
