[lugfcqhu] gendered chess piece types

define the ranged pieces queen, rook, and bishop to be female.

define the non-ranged pieces king, knight, and pawn to be male.

but I can't think of any good reason to do this, though it is elegant that the piece types divide half and half.  mnemonic: the sexist trope in fiction that only men are tough enough to do melee combat; women like Katniss and Aerith (but not Tifa) specialize in ranged attacks from afar.

orthodox chess does not have artillery which can kill from afar without moving.  fairy chess could add such truly female pieces.

pawn promotion might be a sex change.
