Dai shogi

Dai shōgi is a board game native to Japan. It is similar to standard shogi in its rules and game play. Dai shogi is only one of several large board shogi variants. Its name means large shogi, from a time when there were three sizes of shogi games...

. The three Edo-era sources are not congruent in their descriptions of the pieces not found in smaller games. Apart from its size and number of pieces, the major difference from these smaller games is the "promotion by capture" rule. A more compact modern proposal for the game is called hishigata shogi.

Objective

The objective is to capture the opponent's king or emperor. If a prince is in play, it too must be captured. Unlike standard shogi

Game equipment

Two players, Black and White (or sente and gote), play on a board composed of squares in a grid of 19 ranks (rows) by 19 files (columns) with a total of 361 squares. The squares are undifferentiated by marking or color.

Each player has a set of 96 wedge-shaped pieces of 50 different types. In all, the players must remember 74 different moves. The pieces are of slightly different sizes, from largest to smallest (or roughly most to least powerful) they are:

• 1 King
• 1 Hook mover
• 1 Capricorn
• 1 Free king
• 2 Dragon kings
• 2 Dragon horses
• 2 Rooks
• 2 Bishops
• 2 Side fliers
• 1 Lion
• 1 Lion dog
• 1 She-devil
• 1 Wrestler
• 1 Guardian of the Gods
• 1 Buddhist devil
• 2 Violent oxen
• 2 Flying dragons

• 2 Old rats
• 1 Right chariot
• 1 Left chariot
• 2 Vertical movers
• 2 Side movers
• 1 Phoenix
• 1 Kirin
• 2 Donkeys
• 2 Knights
• 1 Drunken elephant
• 2 Blind tigers
• 2 Ferocious leopards
• 1 Reclining dragon
• 2 Gold generals
• 2 Silver generals
• 2 Copper generals
• 2 Tile generals

• 2 Evil Wolves
• 2 Iron generals
• 2 Stone generals
• 2 Reverse chariots
• 2 Lances
• 2 Earth generals
• 2 Go betweens
• 2 Blind bears
• 1 Chinese cock
• 1 Old monkey
• 2 Angry boars
• 2 Cat swords
• 1 Coiled serpent
• 1 Dark spirit
• 1 Deva
• 19 Pawns

Many of the English-language names are chosen to correspond to their rough equivalents in Western chess, not necessarily as translations of the Japanese names.

Each piece has its name in the form of two Japanese characters marked on its face. On the reverse side of some pieces are one or two other characters, often in a different color (e.g., red instead of black); this reverse side is used to indicate that the piece has been promoted during play. The pieces of the two sides do not differ in color, but instead each piece is shaped like a wedge, and faces forward, toward the opposing side. This shows who controls the piece during play.

Table of pieces

Listed below are the pieces of the game and, if they promote, which pieces they promote to. Of the 50 kinds of pieces, 21 promote to gold, 26 promote to new pieces (though some move like starting pieces, e.g. the free cat moves like a bishop, the free iron & gopher like a reverse chariot); and 3 do not promote (free king, dragon king, and dragon horse).

Game play

The players alternate making a move, with Black moving first. (The traditional terms 'black' and 'white' are used to differentiate the sides during discussion of the game, but are not literally correct.) A move consists of moving a piece on the board and potentially promoting the piece. Each of these options is detailed below.

Movement and capture

Most pieces in the game move in a unique manner. The kings, drunken elephants, blind tigers, ferocious leopards, reclining dragons, Chinese cocks, old monkeys, evil wolves, generals, angry boars, cat swords, coiled serpents, dark spirits, Devas, go betweens and pawns only move one square at a time. If an opponent's piece occupies a square that is a possible destination for the moving piece, the opponent's piece may be captured by placing the moving piece on that square, and removing the opponent's piece from the board. If a friendly piece (that is, a piece controlled by the same player) occupies the square, the moving piece may not move in that direction.

The lion dog, she-devil, wrestler, guardian of the Gods, Buddhist devil, violent ox, flying dragon and old rat can move along a limited number of free squares in certain directions.

The lion, kirin, phoenix, donkey and knight jump, that is, they can move over any intervening piece, whether friend or foe.

The free king, dragon king, dragon horse, chariots, rook, bishop, side flier, movers and lance can move any number of squares along a straight line, limited by the edge of the board. If an opponent's piece intervenes, it may be captured by moving to that square, and removing it from the board. If a friendly piece intervenes, the moving piece is limited to a distance that stops short of the intervening piece; if the friendly piece is adjacent, it cannot move in that direction at all.

The hook mover and Capricorn can move any number of squares along a straight line, then any number of squares along a perpendicular straight line limited by the edge of the board. If an opponent's piece intervenes, it may be captured by moving to that square, and removing it from the board. If a friendly piece intervenes, the moving piece is limited to a distance that stops short of the intervening piece; if the friendly piece is adjacent, it cannot move in that direction at all. Although they have the ability to move in two directions in one move, they are not required to. These pieces cannot move unless they make a capture.

The pawn, lance, stone general, iron general, and knight can only move forward. Therefore if one reaches the furthest rank (or the furthest two ranks in the case of the knight), it is unable to move further, it must remain there until captured.

Pieces move either orthogonally (that is, forward, backward, or to the side, in the direction of one of the arms of a plus sign, +), or diagonally (in the direction of one of the arms of a multiplication sign, ×). The lion and knight are exceptions.

Second rank

• Drunken elephant 醉象
  • The drunken elephant can move one square in any direction, orthogonal or diagonal, except orthogonally backward.

Third rank

• Lion 獅子
  • The lion can move one square in any direction, orthogonal or diagonal; one or two times in one turn. That is, it can move in another direction after its first move.
  • It can capture on each move.
  • It can return to the square it started from after its first move, allowing the player to "skip" a turn.
  • It can capture one piece on any adjacent square without moving ("igūi") during a turn.
  • It can jump over an adjacent square and onto the second square in any direction, orthogonal or diagonal.
  • It can also jump at an angle intermediate between orthogonal and diagonal; amounting to one square orthogonally forward, sideways or backward plus one square diagonally in that direction, in a single motion.

• Old rat 老鼠
  • The old rat may have moved one or two squares diagonally forward or orthogonally backward.

Fourth rank

• Lion dog 狛犬
  • The lion dog has a triple-step move in any direction, orthogonal or diagonal. However, unlike the lion, it is constrained to one of these directions. It can jump, and need not take all three steps:
    • It can move one, two, or three squares in any one direction, potentially capturing pieces on each square.
    • It can snatch a piece from an adjacent square without moving (or, equivalently, move to an adjacent square and return) (igui).

• Violent ox 猛牛
  • The violent ox can move one or two squares in one of the four orthogonal directions.

• Knight 桂馬
  • A knight jumps at an angle intermediate between orthogonal and diagonal, amounting to one square forward plus one square diagonally forward, in a single motion. That is, it has a choice of two forward destinations.
  • The knight ignores intervening pieces on the way to its destination, though its destination square must of course be either empty, or occupied by an opponent's piece (in which case the opponent's piece is captured), just as with any other moving piece.

• Donkey 驢馬
  • The donkey can move one square in one of the four orthogonal directions; or
  • It can jump to the second square orthogonally forward or backward.

Fifth rank

• Free king 奔王
  • The free king can move any number of free squares in any direction, orthogonal or diagonal.

• Capricorn 摩羯 (摩𩹄)

  • The vertical mover can move any number of free squares orthogonally forward or backward; or
  • It can move one square orthogonally sideways.

• Side flier 横飛

  • The go between is identical to the earth general: It can move one square orthogonally forward or backward.

Promotion

Pieces that can promote only have the option to promote when they capture an unpromoted enemy piece. If a piece captures a promoted piece, it must promote if able. Promotion is indicated by turning the piece over after it moves, revealing the character for the promoted piece. There are no promotion zones; dots on the board that usually represent promotion zones are present after the sixth rank only as a placement guide for initial setup.

Promoting a piece has the effect of changing how that piece moves. (See above for what each piece promotes to.)

Pieces which are already promoted cannot promote again, except as follows:

Any piece, promoted or not, that captures a Deva or Teaching king (a promoted Deva) promotes to a Teaching king. This is effected by replacing it on the board with the captured piece. Similarly, any piece that captures a Dark spirit or Buddhist spirit (a promoted Dark spirit) promotes to a Buddhist spirit.

Pieces on the 4th, 5th, and 6th ranks which promote, as well as the outside pieces of the 1st and 2nd ranks, promote (or perhaps demote) to Gold. New powers that appear as a result of promotion of the other pieces are as follows:

• Twelve of the pieces in the first and second ranks, as well as the go-between, become "free" when promoted, meaning that they move in the same directions as in their unpromoted state, but are free to move an unlimited number of squares in those directions. They are:
  • Free gold 奔金
  • Free silver 奔銀
  • Free copper 奔銅
  • Free iron 奔鉄
  • Free tile 奔瓦
  • Free stone 奔石
  • Free earth 奔土
  • Free tiger 奔虎
  • Free leopard 奔豹
  • Free serpent 奔蛇
  • Free (reclining) dragon 奔龍 ?
  • Free cat 奔猫
  • Free goer/gopher 奔人

Pieces with entirely new powers are:

• Emperor 自在天王
  • The emperor can jump to any unprotected square on the board.
  • It can jump to a protected square if a prince is in play (not recommended).
  • It cannot capture a protected piece, (e.g., placing it in check with a capture, whether or not a prince is in play) even if this move will win the game.
  • If a prince is not in play and both players have an emperor, then the emperor cannot move to a square that is not protected by a friendly piece. That is, the emperor must be protected from the other emperor at all times.

• Teaching king 教王
  • The teaching king can move as either a lion dog or as a free king. However, in Western descriptions, this has been said to be a modern innovation, with the traditional move said to simply be that of a free king.
    • It can move as a free king, free-ranging in any one direction, orthogonal or diagonal.
    • It has a triple-capture move in any direction, orthogonal or diagonal.

• Buddhist spirit 法性

  • The bat can move any number of free squares orthogonally forward or diagonally backward.

Check and mate

When a player makes a move such that the opponent's king, emperor or prince (sole one in play) could be captured on the following move, the move is said to give check to the king, emperor or prince; the king, emperor or prince is said to be in check. If a player's king, emperor or prince is in check and no legal move by that player will get the king, emperor or prince out of check, the checking move is also a mate, and effectively wins the game. If a player has both a king (or emperor) and prince in play, then the player need not move only one out of check.

A player is not allowed to give perpetual check

Perpetual check

In the game of chess, perpetual check is a situation in which one player can force a draw by an unending series of checks. Such a situation typically arises when the player who is checking cannot deliver checkmate; while failing to continue the series of checks gives the opponent at least a chance...

 to the sole objective piece.

Game end

A player who captures the opponent's king (or emperor, which is a promoted king) or prince (when the other is already gone) wins the game. In practice this rarely happens; a player will resign when loss is inevitable and the king (emperor) or prince will be taken on the opponent's next move (as in International Chess) because of the tradition that it is seen as an embarrassment to lose.

A player who makes an illegal move loses immediately. (This rule may be relaxed in casual games.)

Another possible (but fairly uncommon) way for a game to end is repetition (sennichite). If the same position occurs four times with the same player to play, then the game is no contest. (Recall, however, the prohibition against perpetual check.)

Game notation

The method used in English-language texts to express shogi moves was established by George Hodges in 1976. It is derived from the algebraic notation used for chess

, but differs in several respects. Modifications have been made for maka dai dai shogi.

A typical example is P-8g.
The first letter represents the piece moved (see above).
Promoted pieces have a + added in front of the letter. (e.g., +OM for a mountain witch (promoted old monkey). The designation of the piece is followed by a symbol indicating the type of move: - for an ordinary move or x for a capture. Next is the designation for the square on which the piece lands. This consists of a number representing the file and a lowercase letter representing the rank, with 1a being the top right corner (as seen from Black's point of view) and 19s being the bottom left corner. (This method of designating squares is based on Japanese convention, which, however, uses Japanese numerals

 instead of letters. For example, the square 2c is denoted by 2三 in Japanese.)

If a lion captures by 'igūi’, the square of the piece being captured is used instead of the destination square, and this is preceded by the symbol '!'. If a double or triple capture is made, then it is added after the first capture.

If a move entitles the player to promote the piece, then a + is added to the end to signify that the promotion was taken, or an = to indicate that it was declined. For example, CSx7c= indicates a cat sword capturing on 7c without promoting.

In cases where the above notation would be ambiguous, the designation of the start square is added after the designation for the piece in order to make clear which piece is meant.

Moves are commonly numbered as in chess.

Hishigata shogi

Sean Humby created a variant of Maka daidai shogi called Hishigata shogi. (See the external link below.) It was motivated by criticisms that maka dai-dai takes a very long time to finish, and that the more interesting pieces have little opportunity for play. The only difference is in the setup, which places the opposing pieces close together and leaves the armies' rear flanks exposed, though Humby recommends that the teaching king be played as the weaker Western variant (as a free king).

Setup

In the hishigata setup, only one rank is left empty between the opposing armies. This is indicated with a darker shading in the diagram below.
