[Retros] The meaning of "C-"

[joost at sanguis.xs4all.nl]

> what does "C-" under a diagram mean?


You basically already answered your own question: It means what the source
has defined for it. In StrateGems and The Problemist, it means 'Not
(fully) computer-tested), in other magazines and publications (e.g.
WinChloe) it means cooked.

I personally prefer 'C+ [possibly with mention of program/version]' for
correct, 'C?' for unknown and 'C-' for cooked.
