Whites pawns are on the seventh (!) or opposing rank, with pieces in FRONT of them in the 8th rank. On the other side blacks pawns are in rank 2 and pieces in rank 1. So you must first move a knight in order to advance a pawn one move forward, to promote it to whatever you wish.
Watch out for smothered mate traps with knights! Openings can otherwise be a bit clumsy but Queens are also easy to come by and don't forget which direction pawns are moving and capturing! Castling is not permitted. Play to checkmate.
