The pawn (♙,♟) is the most numerous piece in the game of chess, and in most circumstances, also the weakest. It historically represents infantry, or more particularly, armed peasants or pikemen. Each player begins a game with eight pawns, one on each square of the rank immediately in front of the other pieces.
Beside this, what can a pawn do in chess?
None of the pawns in this diagram can move. Although a pawn moves straight forward it captures by talking one square diagonally forward. In the diagram White can capture either the Rook or the Knight. She does this by removing the captured piece from the board and replacing it with the pawn.
Can you get a piece back in chess?
The Pawn can never move backwards. If the Pawn reaches the opposite side of the chessboard, it has the unique ability to promote to another chess piece. The pawn can become a Queen, Bishop, Rook, or Knight. There are no restrictions to how many pieces of a given type you can have via promotion.
