Every square has two names. One name is for the white moves and one is for the black moves. Each square is named for the file and then for the rank.
File names are the same for both sides.
Count the ranks from white's side for the white moves. Count the ranks from black's side for the black moves. Each Queen starts on her own Q1, which is the other player's Q10. Position after 4. It may become necessary to distinguish between similar men.
