# Shogi

Shogi (将棋 shōgi), or Japanese chess, is a traditional Japanese strategy board game related to chess. In Japan, it is enjoyed by many people regardless of age or gender. There are professional competitions, but becoming a professional is very difficult, and requires one to start training from childhood.

## Understand
### History

The origins of shogi are unclear, though like all other modern chess variants, it is believed to trace its origin to the Persian game of shatranj, and ultimately in the Indian game of chaturanga. The first known mention of the name dates back to the 11th century, while the rules of the modern game are believed to have been standardized around the 16th century.

### Rules

Shogi is played on a 9x9 board, with each side having 20 pieces. Each player starts the game with 9 pawns (歩兵 fuhyō), 2 lances (香車 kyōsha), 2 knights (桂馬 keima), 2 silver generals (銀將 ginshō), 2 gold generals (金將 kinshō), 1 bishop (角行 kakugyō), 1 rook (飛車 hisha) and 1 king (王將 ōshō or 玉將 gyokushō). By convention, the 王將 king piece is assigned to the higher-ranked player or defending champion, while the 玉將 king piece is assigned to the lower-ranked player or challenger. The objective of the game is to capture the opponent's king.
Like in chess, each piece has its own specific moveset, and capturing an opponent's piece is done by moving into the space occupied by the opponent's piece. The rook moves just like the rook in chess; any number of spaces horizontally or vertically. The bishop also moves just like the bishop in chess; any number of spaces diagonally. The lances may move any number of spaces forward. The knights move in a "L" shape similar to in chess, except that they may only move two steps forward followed by one step horizontally in either direction. Like in chess, the knights may jump over any intervening pieces. The silver generals may move one step diagonally or one step forward, while the gold generals may move one step in any direction except diagonally backwards. The pawns may move one step forward, while the king may move one step in any direction just like the king in chess.
Pieces other than the king and gold general may be promoted when moving into, out of, or within the player's promotion zone, which comprises the last three ranks on the opponent's side of the board. Promotion is done by turning the piece over to the other side, and is usually optional, though it is compulsory if the piece would run out of legal moves otherwise. Promotion is also generally permanent, and promoted pieces may not be returned to their unpromoted state unless they have been captured by the opponent (see the next paragraph on drops). Promoted pieces have different Japanese names and movesets from their unpromoted counterparts. The promoted rook is known as 龍王 (ryūō, lit. dragon king), and gains the ability to move one space diagonally, in addition to the regular rook moveset. The promoted bishop is known as 龍馬 (ryūme, lit. dragon horse), and gains the ability to move one space horizontally or vertically in addition to the regular bishop moveset. Promoted lances are known as 成香 (narikyō), promoted knights are known as 成桂 (narikei), promoted silver generals are known as 成銀 (narigin) and promoted pawns are known as と金 (tokin), and all these pieces move like a gold general after promotion.
A unique feature of shogi is drops, in which a player may return pieces captured from the opponent to the board under the player's control during their turn, which counts as a complete move. Pieces may be dropped on any empty space on the board, barring three conditions. Firstly, pieces may not be dropped onto spaces that will leave them with no legal moves left. Secondly, there cannot be more than one unpromoted pawn in the same file. And lastly, a pawn may not be dropped into a position that will result in an immediate checkmate (though other pieces may). Pieces are always dropped in their unpromoted state, even if they were captured from the opponent while promoted, and a piece may not be promoted on the turn it is dropped.
Like in chess, a king that is in danger of being attacked is said to be in check (王手 ōte), and a player that has no legal moves to prevent the king from being captured is said to be in checkmate (詰み tsumi). Unlike in chess, announcing check to an opponent is generally not done, even as a courtesy, and virtually unheard of in professional tournaments. There is also no stalemate rule in shogi, and a player with no legal moves left loses the game.
The presence of promotions and drops make shogi a game full of tactical richness, and it is generally regarded to have the highest amount of complexity among all chess variants, with draws being extremely rare.

### Tsume shogi

Tsume shogi is a puzzle that uses the rules of shogi. Several pieces are placed on the shogi board such that the opponent's king can be placed in check on the next round. The goal of the game is to checkmate the opponent's king with a series of checks, and all the attacking side's moves are required to be checks. It is used for practicing shogi from beginners to advanced players.

#### Goita

There is a tablegame called "Goita", which is played like a card game with tiles similar to Shogi pieces. Goita originated in the Ushitsu area, a fishing village in "Noto-cho, Fugeshi-gun, Ishikawa (石川県鳳至郡能都町)".
