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.
