input: Promotion (chess)

Promotion is a chess rule that requires a pawn that reaches its eighth rank to be immediately replaced by the player's choice of a queen, knight, rook, or bishop of the same color . The new piece replaces the pawn, as part of the same move. The choice of new piece is not limited to pieces previously captured , thus promotion can result in a player owning, for example, two or more queens despite starting the game with one. Pawn promotion, or the threat of it, often decides the result in an endgame. Since the queen is the most powerful piece, the vast majority of promotions are to a queen. Promotion to a queen is often called queening; promotion to any other piece is referred to as underpromotion (Golombek 1977).
