	bool menu = true;

	cin >> x >> y;

	x -= 97;


	for (int row = 0;row <= 8; row++)
	{

Since a rook can move only up or down vertically and either left or right horizontally if the fields are empty or occupied by an enemy piece.
For example:
if the rook is on row 0 and col 0 then it can move to row 1 col 0 when the field is empty or an enemy piece is there. Same principle is for horizontal move.
