So look at the board on the left and contrast with the right. White always moves first, and the board positions are based on white, they start in the lower left, files are the vertical columns, ranks are the horizontals.
Ranks are numbers, files are letters with 64 squares in total.
Position A-1 should be on whites left side....

That being said the board on the left should be blacks starting side, see how the A is on the right instead of the left? The board has been flipped, white is on blacks side and black is on whites side.
