The Japanese term for "piece(s) in hand" is either 持ち駒 "mochigoma" or 手駒 "tegoma." On any turn, instead of moving a piece on the board, a player may select a piece in hand and place it – unpromoted side up and facing the opposing side – on any empty square. The piece is then one of that player's active pieces on the board and can be moved accordingly. This is called "dropping" the piece, or simply, a "drop". A drop counts as a complete move. A drop cannot capture a piece, nor does dropping within the promotion zone result in immediate promotion. Capture and/or promotion may occur normally, however, on subsequent moves of the piece. Restrictions. There are three restrictions on dropping pieces. The last two restrictions apply only to pawns. It is common to keep captured pieces on a wooden stand (駒台 "komadai)" which is traditionally placed so that its bottom left corner aligns with the bottom right corner of the board from the perspective of each player. It is not permissible to hide pieces from full view. It is common for players to swap bishops, which oppose each other across the board, early in the game. This leaves each player with a bishop in hand to be dropped later. The ability for drops in shogi give the game tactical richness and complexity. The fact that no piece ever goes entirely out of play accounts for the rarity of draws. When a player's move threatens to capture the opposing king on the next turn, the move is said to "give check" to the king and the king is said to be "in check." If a player's king is in check, that player's responding move must remove the check if possible. Ways to remove a check include moving the king away from the threat, capturing the threatening piece, or placing another interposing piece between the king and the threatening piece. To announce check in Japanese, one can say "ōte" (). However, this is an influence of international chess and is not required, even as a courtesy. Announcing a check vocally is unheard of in serious play. The usual way for shogi games to end is for one side to checkmate the other side's king, after which the losing player will be given the opportunity to admit defeat. Unlike western chess or xiangqi, checkmate is almost always the end result in shogi since pieces never retire from play which gives the players a sufficient number of pieces to deliver checkmate.
