    Pieces and their promoted forms, with movements summary.

h3 General rules

ul
  li.
    The three farthest ranks are the promotion zone.
    Every starting piece except the king and queen may promote by moving into
    the promotion zone or moving from within the promotion zone.
  li.
    However, only one of each major piece (queen, mortar, archbishop, or
    general) can be out on each side at a time.
  li.
    Captured pieces may be dropped back into the board as your own piece.
    Pieces can be dropped anywhere within the first 5 ranks.
  li.
    When promoted pieces are captured, they revert to their unpromoted side.
    This is the only way that a queen becomes a duchess.

p Note: pawns cannot promote if capturing en passant.
