Apart from the King and the Gold, any piece can be promoted to a more powerful piece when it makes a move completely or partly in the promotion zone. So, when a piece moves into, out of or fully inside the promotion zone it may be promoted upon completion of its move. In Shogi sets promoting a piece is done by turning this pieceupside down. Its promoted name is written on its other side. When one piece moves onto the same square as an opponent's piece, the opponent's piece is captured.
All pieces capture in the same way that they move.
Captured pieces become part of the capturer's force. In a later move, instead of moving a piece on the board, a player may put a piece that he has captured from his opponent back onto the board, in an empty square. This is called dropping a piece. After dropping a piece it must be able to make a legal move. This applies to Pawns, Knights or Lances.
