So a queen is of course a girl right? At least in ancient time

and pawns can turn into a queen

so all pawns must be girls too

and pawn can turn into any piece except the king

that means all the pieces beside the king is a girl

 

so basically, Chess is a harem war between 2 sides, and then you steal each harem member one by one, like NTR

 

This is why Chess is hot
