Pawns move towards the opponent's side. They capture obliquely forward to an adjacent field (in rook's directions). They can advance two fields from their initial position. When a pawn moves to an other pawn's initial position by capturing, it can still make a double-move.
Pawns promote on the opposite two edges of the board.
