Seravajan: I know Fencer does not really like making variants of variants, but I would second a Crazy Dark Screen Chees variant. (Don't think we need both Screen & Crazy Screen dark variants - and since regular screen chess is the least popular game on the site, don't think we need a dark variant of the regular screen chess.)

Just thinking about the game, I would think white would have a good advantage - giving a lot more importance of placing the bishops & rooks to be able to view as much of the opponents opening as possible.

Anyway, I know Fencer is some-what against making variants of variants, but this would be fun - plus should not be too hard to program.
