Tai shogi

Tai shogi is essentially a merger of two other large-board shogi variants: dai dai shogi and maka dai dai shogi. Almost all the pieces of those two smaller games are included, and where the same pieces are found, they move the same way. Additionally, many of the tai shogi pieces not from those two games already appear in the even more popular chu shogi. Only nine extra pieces are added that do not appear in any smaller games – the peacock, soldier, vermillion sparrow, turtle-snake, side dragon, golden deer, silver hare, fierce eagle, and ram's-head soldier. (Indeed, two of the Edo-era sources generally do not describe a piece for tai shogi if it exists in a smaller variant.)

The promotion rule is contested. Dai dai shogi and maka dai dai shogi have very different promotion rules. The promotion rules given on the Japanese Wikipedia are similar to those of maka dai dai shogi: almost all pieces promote, but most to the lowly gold general, even if they are much more powerful; and many weak pieces turn into "free" versions of themselves (in which stepping moves are replaced by unlimited ranging moves in the same directions). However, the promotion rules given in English-language sources are similar to those of dai dai shogi: most pieces do not promote. Both agree that promotion is compulsory upon capture if the piece can promote.

In maka dai dai shogi with its demotions, The Chess Variant Pages suggest that promotion is only compulsory when capturing a promoted piece, which seems more reasonable because otherwise the most powerful pieces would quickly disappear. However, in tai shogi non-promoting copies of those powerful pieces can be obtained by promoting some weak pieces.

The difference is unusual: in all smaller variants, Japanese Wikipedia agrees with the English-language sources on promotions, even though it does not always agree on the moves. There are additionally some confusions in the Japanese Wikipedia promotions: for example, the fragrant elephant is said to exist in tai shogi, but without a piece promoting into it. Because of this, the promotions from the English-language sources have been followed throughout this article, with alternatives given in the footnotes. That is, most pieces do not promote, and promotion (if possible) is compulsory on capture.

The objective of the game is to capture the opponent's emperor and prince (or princes). When the last of these is captured, the game ends. There are no rules for check or checkmate; however, in practice a player resigns when checkmated.

Two players, Black and White (or 先手 sente and 後手 gote), play on a board ruled into a grid of 25 ranks (rows) and 25 files (columns), for a total of 625 squares. The squares are undifferentiated by marking or color.

Each player has a set of 177 wedge-shaped pieces of 93 types. In all, the players must remember 100 moves for these pieces. The pieces are of slightly different sizes. From largest to smallest (or roughly most to least powerful) they are:

Several of the English names were chosen to correspond to rough equivalents in Western chess, rather than as translations of the Japanese names. (Sometimes the queen is called the "free king", a direct translation of its Japanese name. The kirin's name is sometimes anglicised as kylin.)

Each piece has its name in the form of two kanji written on its face. On the reverse side of some pieces are one or two other characters, often in a different color (commonly red instead of black); this reverse side is turned up 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.

Listed here are the pieces of the game and, if they promote, which pieces they promote to.

:* The first kanji in 'howling' dog, 𠵇[https://www.unicode.org/cgi-bin/GetUnihanData.pl?codepoint=20D47], is not supported by many fonts, and so is created here with the help of an ad hoc superscript ^口 . Likewise, the second character in 'Capricorn' should be composed of 魚+曷 (𩹄[https://www.unicode.org/cgi-bin/GetUnihanData.pl?codepoint=29E44]), and the second character in 'wizard stork' should be 而 atop 鷦 (15px).

Below is a diagram showing the setup of one player's pieces. The way one player sees their own pieces is the same way the opposing player will see their pieces.

The queen could also be abbreviated FK (for free king) and the kirin as Ky (for kylin).

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 no longer literally descriptive.) A move consists of moving a single piece on the board and potentially promoting that piece or displacing (capturing) an opposing piece. Each of these options is detailed below.

An opposing piece is captured by displacement: That is, if a piece moves to a square occupied by an opposing piece, the opposing piece is displaced and removed from the board. A piece cannot move to a square occupied by a friendly piece (meaning another piece controlled by the moving player).

Each piece on the game moves in a characteristic pattern. Pieces move either orthogonally (that is, forward, backward, left, or right, 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 emperor, lion, and knight are exceptions at the beginning of the game, in that they do not move, or are not required to move, in a straight line. (The Buddhist spirit and furious fiend are similar, but they only appear as pieces promote.)

If a piece that cannot retreat or move aside advances across the board until it can no longer move, it must remain there until captured. This applies to the pawn, lance, ram's-head soldier, stone general, wood general, and iron general upon reaching the farthest rank, and to the knight upon reaching either of the two farthest ranks.

Many pieces are capable of several kinds of movement, with the type of movement most often depending on the direction in which they move. The movement categories are:

Some pieces move only one square at a time. (If a friendly piece occupies an adjacent square, the moving piece may not move in that direction; if an opposing piece is there, it may be displaced and captured.)

The step movers are the prince, drunk elephant, neighbor king, blind tiger, blind monkey, ferocious leopard, reclining dragon, Chinese cock, old monkey, evil wolf, the generals (except the wood general), angry boar, cat sword, coiled serpent, deva, dark spirit, go between, and the 25 pawns on each side.

Some pieces can move along a limited number (2, 3, or 5) of free (empty) squares along a straight line in certain directions. Other than the limited distance, they move like ranging pieces (see below).

These pieces are the water buffalo, standard bearer, vermillion sparrow, turtle-snake, blue dragon, white tiger, dove, she-devil, golden bird, great dragon, white elephant, lion dog, wrestler, Guardian of the Gods, Buddhist devil, golden deer, silver hare, fierce eagle, old kite, violent ox, flying dragon, old rat, enchanted badger, flying horse, prancing stag, violent bear, the barbarians, and the wood general.

Several pieces can jump, that is, they can pass over any intervening piece, whether friend or foe, with no effect on either. These are the lion, kirin, phoenix, poison snake, donkey, and knight.

Many pieces can move any number of empty squares along a straight line, limited only by the edge of the board. If an opposing piece intervenes, it may be captured by moving to that square and removing it from the board. A ranging piece must stop where it captures and cannot bypass a piece that is in its way. 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 ranging pieces are the soaring eagle, horned falcon, queen, rushing bird, the demons, free dream-eater, water buffalo, flying ox, soldier, dragon king, dragon horse, the chariots, rook, bishop, white horse, whale, standard bearer, vermillion sparrow, turtle-snake, blue dragon, white tiger, side dragon, golden bird, great dragon, white elephant, golden deer, movers, howling dog, ram's-head soldier and lance.

The hook mover, long-nosed goblin, Capricorn, and peacock can move any number of squares along a straight line, as a normal ranging piece, but may also abruptly change tack left or right by 90° at any one place along the route, and then continue as a ranging piece. Turning a corner like this is optional.

The range covered by a hook move is the equivalent of two moves by a rook, or two moves by a bishop, depending on the piece. However, a hook move is functionally a single move: The piece cannot capture twice in one move, nor may it capture and then move on. It must stop before an intervening piece (unless it first changes direction to avoid it), and must stop when it captures, just like any other ranging piece. It can only change direction once per move.

The lion, lion dog, soaring eagle, and horned falcon have sequential multiple-capture abilities, called "lion moves". Among the pieces that only appear with promotion, so do the teaching king, buddhist spirit, and furious fiend. The details of these powerful moves are described for the lion, below.

The vast majority of pieces cannot promote. Those that can promote, however, must promote at the end of their first capturing move. 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. All this is as in dai dai shogi.

Promoting a piece has the effect of changing how that piece moves: see the table 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 brought about 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. This is sometimes expressed as the piece being contagious: when something captures a contagious piece type, it becomes that piece type. The only exception is (potentially) royal pieces (emperors, princes, and drunk elephants) which promote to their normal promoted forms or stay as they are if unpromotable or already promoted.

It is not clear what happens if a multi-capturing piece such as a lion or a lion dog captures two different contagious piece types in one turn, e.g. a lion capturing both a teaching king and a Buddhist spirit on the same turn. Although the situation is very unlikely to arise, an official of the Japanese Chu Shogi Association has suggested in discussion with H. G. Muller (who programmed an engine HaChu for chu shogi and wrote the descriptions for some large shogi variants for The Chess Variant Pages) that the multi-capturing piece would promote to the last piece captured. In the case of a lion dog capturing two pieces on the same orthogonal or diagonal, the official claimed that it would not be permitted to jump over the first piece, capture the second, and then move back to capture the first, though Muller admits that the logic did not "make much sense" to him and that he would be happy with the option to choose. (Note that this situation is extremely theoretical anyway, because allowing both these powerful pieces to be captured at once would imply very poor play.){{Cite web|url=https://www.chessvariants.com/index/listcomments.php?id=38424|title=chessvariants.com -- Comment Listing|website=www.chessvariants.com|accessdate=Jan 26, 2023}}

Otherwise, pieces don't promote more than once: they only have two sides.

In the diagrams below, the different types of moves are coded by symbol and by color: Blue for step moves, yellow for jumps, green for multiple capture, and pink for range moves, as follows:

Piece names with a grey background are present at the start of the game; those with a blue background only appear with promotion. Betza's funny notation has been included in brackets for easier reference, with the extension that the notation xxxayyyK stands for an xxxK move followed by an yyyK move, not necessarily in the same direction. Larger numbers of 'legs' can be indicated by repeated application of 'a'. Directional modifiers on continuation legs must be interpreted relative to the previous leg, where 'f' means 'continue in the same direction'; default is 'all directions'. The default modality of the final leg is the usual 'mc', but on non-final legs also includes a hop over an obstacle at their endpoint, provided the path does not bend back onto itself there. Other (combinations of) modalities must be written explicitly. U denotes the universal leaper, a piece which can jump to any square on the board except the one that it is on.

There are many divergent descriptions in the Edo-era sources. However, almost all the pieces in tai shogi already appear either in dai dai shogi or maka dai dai shogi, and so they are presented here identically to how they are on the Wikipedia articles for those two games. Refer to those pages for footnotes detailing divergent moves. Footnotes are presented as usual for pieces that do not appear in smaller games.

• The emperor can jump to any empty square on the board.
• It can jump to and capture any non-royal piece anywhere on the board.
• It can capture a royal piece (prince, king, or the other emperor) anywhere on the board, but only if that piece is unprotected; capturing a protected royal piece is illegal. (U)

:In order to win the game, the opponent must be left with no emperors or princes. Since the drunk elephant also promotes to prince, that means that one might need to capture three royal pieces to achieve victory.

|-style="vertical-align:top;"

|

• The great elephant, should it exist in this game (there is some dispute on this point among the Edo-era sources), can move any number of free squares along one of the four orthogonal directions, or diagonally backward.
• It can move up to two free squares along either of the forward diagonals.

The furious fiend does not exist except as a promoted lion (below).

|-style="background:#e0e0e0;"

| Lion dog 狛犬 komainu

| Lion 獅子 shishi

|-style="vertical-align:top;"

|

• The lion dog can make a three-step lion move along any one of the eight orthogonal or diagonal directions. That is, unlike the lion itself, but like the soaring eagle and horned falcon, it is restricted to moving along a straight line and cannot move to the in-between squares. This lion power includes jumping, igui, and skipping a turn.
• A piece may be captured on all three steps.
• The lion dog may capture a piece on the first and second square, and then retreat to the first square. Or it may snatch a piece off the first square as in normal igui. (Note however that it may not then continue in the opposite direction: it is restricted to one orthogonal or diagonal.)
• It may jump to the second square, and then continue to the third square, capturing up to two pieces. Or it may jump directly to the third square.
• It is not required to take all three steps. (KavKafavK)

As it finishes a capturing move, the lion dog promotes to a great elephant (above). In rules that do not use the great elephant, the lion dog cannot promote.

|

• The lion can step in any direction, and capture, up to twice a turn. The two steps do not need to be in the same direction, so this move is equivalent to two turns of a king. As a piece does not promote until its turn ends, an unpromoted lion has a chance for a double capture.
• By moving back to its starting square, it can effectively capture a piece on an adjacent square without moving. This is called 居喰い igui "stationary feeding".
• It can also do the same to an empty square, without capturing anything. This is traditionally indicated by tapping the lion and leaving it in place.
• A lion can jump anywhere within a distance of two squares: That is, anywhere it could reach in two step-moves on an empty board, though of course it cannot land on a square occupied by a friendly piece. This is equivalent to jumping in any of the eight diagonal or orthogonal directions, or making any of the jumps of a knight in Western chess. (NADaK)

As it finishes a capturing move, the lion promotes to a furious fiend (above).

|-

|

• 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. (ffN)
• 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.

(fBfWbRbB2)In Steve Evans' Shogi Variants software, the moves of the vermillion sparrow and turtle-snake are interchanged.Japanese Wikipedia gives a completely different move for the vermillion sparrow: any number of free squares along the forward right or rear left diagonals, or one square orthogonally or on the rear right diagonal. It has no move along the fore left diagonal. ([fr][bl]BW[br]F)

|

• The turtle-snake can move any number of free squares diagonally or directly forward; or,

(fQbWbB2)Japanese Wikipedia gives a completely different move for the turtle-snake: any number of free squares diagonally forward to the right or diagonally backward to the left, or one square in any direction. ([fr][bl]BW) Since Japanese Wikipedia also describes the piece this way for taikyoku shogi, which often has unique movements for its pieces, this may be an error, especially as it is not the mirror image of the vermillion sparrow.
