corollary of the second restriction is that a player with an unpromoted pawn on every file is unable to drop a pawn anywhere. For this reason, it is common to sacrifice a pawn in order to gain flexibility for drops. Captured pieces are typically kept 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 gives the game tactical richness and complexity. The fact that no piece ever goes entirely out of play accounts for the rarity of draws. Check 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. It may be common to announce ōte in beginner matches or for local rules to dictate that you have to announce it. Announcing a check vocally is unheard of in serious play. End of the game 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 result in shogi since pieces never retire from play which gives the players a sufficient number of pieces to deliver checkmate. That said, there are three other possible ways for a game to end: repetition ( sennichite), impasse ( jishōgi), and an illegal move (). The first two – repetition and impasse – are particularly uncommon. Illegal moves are also uncommon in professional games although this may not be true with
