diogenes: I know at one time, Fencer did not like the idea of making variants of variants, but I would agree that a few dark variants of variants would be a great addition. For a chess player like me (Not very good), I always feel I have a better chance at dark chess and would love to see dark cylinder chess, dark knight relay, and dark crazy screen chess.

Dark loop chess would be interesting, along with dark Majarajah Chess - which might give white a little more of a chance to get a "surprise" win.

About the only Chess variants that it would not work too well with is Ambiguous Chess. Los Alamos Chess probable would not work too well since the board is already pretty small.

Fencer could almost double the amount of chess games if he wanted to. But of course right now, Dark Chess is the 47th most popular game so the question would be is it worth making more variants which probable would not top the original?
