text: On the reverse side of each piece, other than the king and gold general, are one or two other characters, in amateur sets often in a different color (usually red); this side is turned face up during play to indicate that the piece has been promoted.
text: A king or a gold general does not promote; nor can a piece that is already promoted.
text: Promotion is, however, permanent – once a piece is promoted it cannot be demoted back into its original form until it is captured.
text: A piece can be promoted when it makes a move that starts and/or ends at the aforementioned promotion zone (i.e. when it moves either into, out of, or wholly within the zone).
text: In this variant, there is no promotion zone at all; instead, pieces can only be promoted upon capturing an opponent piece.
text: Promotion is optional if the captured piece is unpromoted, but mandatory if the captured piece is promoted.
