Obscure chess variants
Not sure what you mean by 'obscure'. If you want a variant that is similar to FIDE, but which not many people play, you could try 'Contageous Queen'. The setup and rules are exactly like orthodox Chess, except that Pawns cannot promote to Queen on reaching the last rank, but any piece other than King that captures a Queen will promote to Queen.
Name an obscure chess variant you think is fun. I'm getting bored of the "standard" variants.
