Judd, you are apparently asking if a pawn can move diagonally forward when
moving from the 7th to the 8th rank. Unless it is capturing an opponent's
piece, the answer is no. A standard FIDE pawn may never move diagonally
forward unless it is capturing. There are other types of pawns that may
move diagonally forward, such as the Berolina pawn, but they have their
own limitations.
