Chess|Pawn
The pawn in Chess moves in one of three ways:
*On its first move, a pawn may advance two cells forward if it is not obstructed by another piece.
*On subsequent moves, a pawn advances exactly one cell forward if not obstructed.
*A pawn may capture an opponent's piece that is placed either to the right or left diagonally.
A pawn which reaches the opposite home row is promoted to queen, rook, bishop, or knight as the player chooses. If a pawn advances two cells and then lands beside an opponents pawn, it is still allowed to capture as if it had only moved up one; this is called en passant.
