Shōgi is a strategy game of the same family as Xiangqi and Chess, and evolved in Japan. It is played on a 9x9 board.
The King moves like in Chess and does not promote.
The Gold Generals (each player starts with two) move one square orthogonally or one diagonally forward. They do not promote.
The Silver Generals (each player starts with two) move one square diagonally or one forward, like the Bishops in Makruk. They can promote to Gold General in rows 7, 8, or 9.
The Knights (each player starts with two) move two squares forward and one to the side. This means they have a maximum of two legal moves, and must promote to Gold General when they reach row 8 or 9. Like the Knights of Chess, they can jump pieces.
The Lances (each player starts with two) can move any number of spaces forward, and must promote to Gold General when they reach row 9.
The Rook (each player starts with one) moves like in Chess. In rows 7, 8, or 9, it can promote (and move like a Rook or a King)
The Bishop (each player starts with one), moves like in Chess. In rows 7, 8, or 9, it can promote (and move like a Bishop or a King)
The Pawns (each player starts with nine, and can have a maximum of nine unpromoted in play) move and capture one square forward. They must promote to Gold General when they reach row 9.
Unlike in other games of the Chaturanga family, players can return pieces they captured to the board. Promotable pieces can be promoted at any time in the opponent's home ranks. If a piece is captured, the promotion is undone.Shogi is the most complex of the common chess variants; Feng Hsiung-Hsu, the initial creator of the series of computer systems that eventually became IBM's Deep Blue chess champion computer, has expressed an interest in creating a shogi system in the same vein should he ever get back into the computerized strategy gaming business.
Blessed with Suck: You can promote a Silver General, but a Gold General finds it harder to retreat if need be.
Brought Down to Normal: When a promoted piece is captured, it not only changes sides but becomes "un-promoted."
Expansion Pack: Numerous medieval variants played on increasingly large boards with increasingly baroque rulesets; some involve boards as large as 36x36, with each player controlling hundreds of pieces.
Kyu and Dan Ranks: Like in Go, these are used in the professional scene. Amateur players in-training to become professionals through the Shoreikai system are ranked from 6 kyu to 3 dan. Kishi (i.e. professional players) rank from 4 dan to 9 dan.
Nerf: The Lances (in the Rooks' places in other games) and Knights are one-way movers.
Serious Business: Full-time professional players compete for big prizes in Japan.
That One Rule: Shogi rules are mostly straightforward, but the process for determining the winner if a stalemate occurs from both sides achieving 'entering King' is unintuitive and not easily remembered because of how rare the situation is.
Since there is no limit to the number of times a piece can switch in this manner, it's possible for a piece to be in a Heel-Face Revolving Door.
Vehicular Turnabout: The strategy game allows you to bring back captured pieces on your side as early as your next turn. This is said to be inspired by the actions of mercenaries who would switch sides when captured, rather than be executed.
