Chess Board Rank File
You want to compare the Ranks versus the Files on a Chessboard. Ney problem.
On a Chessboard, the Ranks are formed out of the squares in a horizontal line - in tables, they're known as 'Rows'.
Anyway, a Chessboard has 8 Ranks, which are numbered 1 to 8, from White's territory, up to Black's territory.
The Ranks, on a Chessboard are formed out of the squares in a vertical line - again, in tables, these are known as 'Columns'.
A Chessboard has 8 Files, which are numbered a to h and they sweep from left to right, or from the Queenside to the Kingside.
