pawns move differently than other pieces. unlike all the other pieces, pawns cannot move backwards. most of the time, a pawn moves by going up a single square, but the first time each pawn is moved from its starting place, it can go forward two squares. pawns cannot use the first two-square move to jump over a square with another piece on it or to capture. any piece in front of a pawn, white or black, stops its moving. if a pawn touches the other side it is exchanged for one of the players pieces that got captured.
