A player's "promotion zone" consists of the three farthest ranks, at the original line of the opponent's pawns and beyond (that is, the opponent's territory at setup). If a piece "crosses" the board within the promotion zone, including moving into, out of, or wholly within the zone, but "not" including drops (see below), then that player may choose to "promote" the piece at the end of the turn. Promotion is effected by turning the piece over after it moves, revealing the name of its promoted rank.
