p.boxed.
  Capturing pieces absorb the movement abilities of the captured pieces,
  except for pawns and kings.

p.
  When one non-royal piece (not a king or a pawn) captures another piece
  (not a pawn), it acquires the movement abilities of the captured piece.
  A pawn capturing a piece becomes a piece of that kind.

  Three new pieces are likely to appear during the game: from left to right
  the Princess, Empress and Amazon, adding the knight movement abilities
  to the bishop, rook and queen.
