In the good old days when I saw a chess diagram I didn't have to guess which way the pawns were going; there was a convention that the white pawns moved up the board. When and why did upside down diagrams become fashionable? Does it have something to do with playing chess on the internet, or did this foolishness come before the internet?
And why don't they ever rotate the diagram 90 degrees, to give us the kibitzer's view of the board?
