'''Xiangqi''' ({{IPAc-en|ˈ|ʃ|ɑː|ŋ|tʃ|i}}; {{zh|c=象棋|p=xiàngqí}}), commonly known as '''Chinese chess''' or '''elephant chess''', is a [[Strategy game|strategy]] [[board game]] for two players. It is the most popular board game in China. Xiangqi is in the same family of games as [[shogi]], [[janggi]], [[chess|Western chess]], [[chaturanga]], and [[Indian chess]]. Besides China and areas with significant ethnic Chinese communities, this game is also a popular pastime in Vietnam, where it is known as '''{{lang|vi|cờ tướng}}''', literally 'General's chess', in contrast with Western chess or ''{{lang|vi|cờ vua}}'', literally 'King's chess'.
The game represents a battle between two armies, with the primary object being to checkmate the enemy's general (king). Distinctive features of xiangqi include the cannon (''pao''), which must jump to capture; a rule prohibiting the generals from facing each other directly; areas on the board called the ''river'' and ''palace'', which restrict the movement of some pieces but enhance that of others; and the placement of the pieces on the intersections of the board lines, rather than within the squares.
{{TOC limit|4}}
==Board==
[[File:Xiangqi board.svg|thumb|Xiangqi board]]
Xiangqi is played on a board nine lines wide and ten lines long. As in the game [[Go (game)|Go]] ({{Lang|ja|圍碁}}; ''or Wéi qí'' {{Lang|zh-hant|圍棋}}), the pieces are placed on the intersections, which are known as ''points''. The vertical lines are known as ''files'' ({{CJKV|c=路|p=lù|l=road}}), and the horizontal lines are known as ''ranks'' ({{CJKV|s=|p=xiàn|l=line|c=線/綫}}).
Centred at the first to third and eighth to tenth ranks of the board are two zones, each three points by three points, demarcated by two diagonal lines connecting opposite corners and intersecting at the centre point. Each of these areas is known as {{Lang|zh-hant|宮}} {{Audio|zh-gong1.ogg|''gōng''|help=no}}, a palace.
Dividing the two opposing sides, between the fifth and sixth ranks, is {{Lang|zh-hant|河}} ''hé'', the "river". The river is usually marked with the phrases {{Lang|zh-hant|楚河}} {{Audio|zh-chu3he2.ogg|''chǔ hé''|help=no}}, meaning "River of the [[Chu (state)|Chu]]", and {{Lang|zh-hant|漢界}} {{Audio|zh-han4jie4.ogg|''hàn jiè''|help=no}}, meaning "Border of the [[Han dynasty|Han]]", a reference to the [[Chu–Han Contention|Chu–Han War]]. Although the river (or ''Hanchu boundary'') provides a visual division between the two sides, only two pieces are affected by its presence: soldiers have an enhanced move after crossing the river, and elephants cannot cross it. The starting points of the soldiers and cannons are usually, but not always, marked with small crosses.
==Rules==
[[Image:2005-07-10 chinese chess.JPG|thumb|left|upright=0.85|Xiangqi is a common pastime in Chinese cities (Beijing, 2005)]]
The pieces start in the position shown in the diagram above. Which player moves first has varied throughout history and from one part of China to another. Different xiangqi books advise either that the black or red side moves first.{{Citation needed|date=February 2010}} Some books refer to the two sides as [[north]] and [[south]]; which direction corresponds to which colour also varies from source to source. Generally, Red moves first in most modern tournaments.<ref>[http://www.chessvariants.com/xiangqi.html Xiangqi: Chinese Chess] {{Webarchive|url=https://web.archive.org/web/20170716074412/http://www.chessvariants.com/xiangqi.html |date=2017-07-16 }} at chessvariants.com</ref>
Each player in turn moves one piece from the point it occupies, to another point. Pieces are generally not permitted to move through points occupied by other pieces, the exception being the cannon’s capturing move. A piece can be moved onto a point occupied by an enemy piece, in which case the enemy piece is captured and removed from the board. A player cannot capture one of their own pieces. Pieces are never promoted (converted into other pieces), although the soldier gains the ability to move sideways after it crosses the river. Almost all pieces capture using their normal moves, while the cannon has a special capture move described below.
[[Image:XiangqiCheckmate.png|thumb|right|An instance of checkmate that assumes the cannon is safe and Black cannot block the check. The horse is not needed for this checkmate.]]
The game ends when one player checkmates the other's general. When the general is in danger of being captured by the enemy player on their next move, the enemy player has "delivered a check" ({{zh|s=|t=照將/將軍|c=|p=|labels=no}}, abbreviated as {{zh|s=|t=將|c=|labels=no}} {{Audio|zh-jiang1.ogg|''jiāng''|help=no}}), and the general is "in check". A check should be announced. If the general's player can make no move to prevent the general's capture, the situation is called "checkmate" ({{zh|s=|t=將死|c=|p=|labels=no}}). Unlike in chess, in which [[stalemate]] is a draw, in xiangqi, it is a loss for the stalemated player.
In xiangqi, a player—often with a material or positional disadvantage—may attempt to check or chase pieces in a way such that the moves fall in a cycle, preventing the opponent from winning. While this is accepted in Western chess, in xiangqi, the following special rules are used to make it harder to draw the game by endless checking or chasing, regardless of whether the positions of the pieces are repeated or not:
* [[Perpetual check]]s with one piece or several pieces are not allowed; doing so results in a loss.
* [[perpetual check#Perpetual pursuit|Perpetual chases]] of any one unprotected piece with one or more pieces, excluding generals and soldiers, are similarly prohibited.<ref name="CXQ">[http://www.clubxiangqi.com/rules/ Chinese Chess Rules] {{Webarchive|url=https://web.archive.org/web/20060813185354/http://www.clubxiangqi.com/rules/ |date=2006-08-13 }} at clubxiangqi.com</ref>
* If one side perpetually checks and the other side perpetually chases, the checking side has to stop or be ruled to have lost.
* When neither side violates the rules and both persist in not making an alternate move, the game can be ruled as a draw.
* When both sides violate the same rule at the same time (note that unlike in western chess, a mutual perpetual check is possible) and both persist in not making an alternate move, the game can be ruled as a draw.
Different sets of rules set different limits on what is considered perpetual. For example, club xiangqi rules allow a player to check or chase six consecutive times using one piece, twelve times using two pieces, and eighteen times using three pieces before considering the action perpetual.<ref name="CXQ"/>
The above rules to prevent perpetual checking and chasing, while popular, are not the only ones; there are numerous end game situations.<ref>{{cite web | url=http://www.clubxiangqi.com/rules/asiarule.htm | title=Asian Chinese Chess Rules}}</ref>
===Pieces===
Each player controls an army of 16 pieces; the armies are usually coloured red and black.<ref name=key>{{cite book |author=Heinrich, Sally |title=Key Into China |page=74 |publisher=Curriculum Press |year=2007 |isbn=978-1863666978}}</ref> Pieces are flat circular disks labelled or engraved with a [[Chinese characters|Chinese character]] identifying the piece type, and in a colour indicating which player has ownership. The black pieces are marked with somewhat different characters from the corresponding red pieces.
On [[mainland China]], most sets still use [[traditional Chinese characters]] (as opposed to [[simplified Chinese characters]]). Modern pieces are usually plastic, though some sets are wooden, and more expensive sets may use [[jade]]. In more ancient times, many sets were simple unpainted woodcarvings; thus, to distinguish between pieces of the two sides, most corresponding pieces used characters that were similar but varied slightly.<ref name=key/> This practice may have originated in situations where there was only one material available to make the pieces from and no colouring material available to distinguish the opposing armies. The oldest xiangqi piece found to date is a {{Lang|zh-hant|俥}} (chariot) piece. It is kept in the [[Three Gorges Museum]].<ref>{{Cite web |last=《中国之最》 |title=中国年代最早的象棋实物出土于重庆 |trans-title=The earliest Chinese chess object was unearthed in Chongoing |url=https://www.do1do2.com/chinasmost/2680 |access-date=2023-03-15 |website=Best of China |date=11 March 2012 |language=zh-CN}}</ref><ref>{{Cite web |last=人民资讯 |date=2023-01-06 |title=最早的中国象棋 万州"车"内发现 |url=https://k.sina.cn/article_7517400647_1c0126e4705903v8x6.html?from=history |access-date=2023-03-15 |website=k.sina.cn}}</ref>
====General====
[[Image:Xiangqi General (Trad).svg|180px|The generals|left]]
[[Image:XiangqiJiangShi.png|thumb|240px|General and advisors]]
'''Generals''' (or '''kings''') are labelled 將 (trad.) / 将 (simp.) {{Audio|zh-jiang4.ogg|''jiàng''|help=no}} ("general") on the black side and 帥 (trad.) / 帅 (simp.) {{Audio|zh-shuai4.ogg|''shuài''|help=no}} ("marshal") on the red side.
The general starts the game at the midpoint of the back edge, within the palace. The general may move and capture one point [[orthogonal]]ly and may not leave the palace, with the following exception.
If the two generals face each other along the same file with no intervening pieces, the 飛將 ("flying general") move may be executed, in which the general to move crosses the board to capture the enemy general. In practice, this rule means that creating this situation in the first place means moving into check, and is therefore not allowed.<ref name="Pieces and Rules of Xiangqi">{{cite web|script-title=zh:象棋简明规则 – 中国棋院在线|url=http://games.sports.cn/server/xiangqi/2008-04-22/1442022.html|access-date=27 May 2014|language=zh}}</ref><ref name="pieces">{{cite web |url=https://www.xiangqi.com/help/pieces-and-moves |title=Pieces and Moves |website=xiangqi.com}}</ref>
The Indian name ''king'' for this piece was changed to ''general'' because of Chinese [[naming taboo]]s; China's rulers objected to their royal titles being given to game pieces.<ref>''[[A History of Chess]]'', p.120, footnote 3 says that Ssŭ-ma Kuang wrote in ''T'ung-kien nun'' in AD 1084 that [[Emperor Wen of Sui]] (541–604) found at an inn some foreigners playing a board game whose pieces included a piece called "''I pai ti''" = "white emperor"; in anger at this misuse of his title he had everybody at the inn put to death.</ref>{{Dubious|date=October 2012|reason=mistranslation}} Despite this, the general is sometimes called the "king" by English-speaking players, due to their similar functions as [[royal piece]]s.<ref name="ancient">{{cite web |url=https://www.ancientchess.com/page/play-xiangqi.htm |title=How to Play Chinese Chess Xiangqi |website=Ancient Chess}}</ref>
====Advisor====
[[Image:Xiangqi Advisor (Trad).svg|180px|The advisors|left]]
'''Advisors''' (also known as '''guards''' and less commonly as '''assistants''', '''[[Mandarin (bureaucrat)|mandarins]]''', '''ministers''' or '''warriors''') are labelled 士 {{Audio|zh-shi4.ogg|''shì''|help=no}} ("scholar", "gentleman", "[[Non-commissioned officer|officer]]", "guardian") for Black and 仕 {{Audio|zh-shi4.ogg|''shì''|help=no}} ("scholar", "official", "guardian") for Red. Rarely, sets use the character 士 for both colours.
The advisors start on either side of the general. They move and capture one point [[diagonal]]ly and may not leave the palace, which confines them to five points on the board.<ref name="pieces"/> The advisor is probably derived from the mantri in [[chaturanga]], like the queen in Western chess.
There is some controversy about whether "士" really is intended to mean "scholar", "gentleman" which would be "士人", or "guard", "guardian" which would be "衛士" (simplified Chinese: 卫士). One argument for the latter is that their functionality seems to be to guard/protect the general. The common Western translation "advisor" does not reflect this layer of meaning.
====Elephant====
[[Image:Xiangqi Elephant (Trad).svg|180px|The elephants|left]]
'''Elephants''' (or '''bishops''') are labeled {{Lang|zh-hant|象}} ''xiàng'' ("elephant") for Black and 相 ''xiàng'' ("minister") for Red. They are located next to the advisors. These pieces move and capture exactly two points diagonally and may not jump over intervening pieces; the move is described as being like the character 田 ''Tián'' ("field"), in reference to the board's squares.<ref name="pieces"/> Blocking an elephant with a diagonally adjacent piece is known as "blocking the elephant's eye" ({{Lang|zh-hant|塞象眼}}).<ref>{{cite web |url=https://www.xiangqi.com/articles/xiangqi-chinese-chess-in-wan-bao-quan-shu-part-1 |title=Xiangqi (Chinese Chess) in Wan Bao Quan Shu Part 1 |last=Png |first=Jim |website=xiangqi.com}}</ref>
Elephants may not cross the river to attack the enemy [[#General|general]], and serve as defensive pieces. Because an elephant's movement is restricted to just seven board positions, it can be easily trapped or threatened. The two elephants are often used to defend each other.
The [[Chinese characters]] for "minister" and "elephant" are [[homophone]]s in [[Standard Chinese|Mandarin]] ({{Audio|zh-xiang4.ogg|Listen|help=no}}) and both have alternative meanings as "appearance" or "image". However, in English, both are referred to as elephants, and less commonly as "bishops", due to their similar movements.<ref name="ancient"/>
====Horse====

{{multiple image|total_width = 410|align = right

|width1 = 240|height1 = 300

|width2 = 328|height2 = 328
|caption2 = Green moves are legal; red ones are illegal because another piece is obstructing the movement of the horse.
}}
'''Horses''' (or '''knights''') are labelled 馬 {{Audio|zh-ma3.ogg|''mǎ''|help=no}} for Black and 傌 ''mǎ'' for Red in sets marked with [[Traditional Chinese characters]] and 马 ''mǎ'' for both Black and Red in sets marked with [[Simplified Chinese characters]]. Some sets use 馬 for both colours. Horses begin the game next to the elephants, on their outside flanks. A horse moves and captures one point orthogonally and then one point diagonally away from its former position, a move which is traditionally described as being like the character 日 ''Rì''.<ref name="pieces"/> The horse does not jump as the knight does in Western chess, and can be blocked by a piece of either colour located one point horizontally or vertically adjacent to it. Blocking a horse is called "[[Hobble (device)|hobbling]] the horse's leg" (蹩馬腿). The diagram on the right illustrates the horse's movement.
Since horses can be blocked, and the path of a horse from one point to another is not the same as the reverse move, it is possible for one player's horse to have an asymmetric attack advantage if an opponent's horse is blocked, as seen in the diagram on the right.
The horse is sometimes called the "knight" by English-speaking players, due to their similar movements.<ref name="ancient"/>
====Chariot====
[[Image:Xiangqi Chariot (Trad).svg|180px|The chariots|left]]
'''Chariots''' (or '''rooks''' or '''cars''') are labelled 車 {{Audio|zh-ju1.ogg|''jū''|help=no}} for Black and 俥 {{Audio|zh-ju1.ogg|''jū''|help=no}} for Red in sets marked with [[Traditional Chinese characters]] and 车 for both Black and Red in sets marked with [[Simplified Chinese characters]]. Some traditional sets use 車 for both colours. In the context of xiangqi, all of these characters are pronounced as {{Audio|zh-ju1.ogg|''jū''|help=no}} (instead of the common pronunciation ''chē''). The chariot moves and captures any distance orthogonally, but may not jump over intervening pieces. The chariots begin the game on the points at the corners of the board. The chariot is often considered to be the strongest piece in the game due to its freedom of movement and lack of restrictions.<ref name="pieces"/>
The chariot is sometimes called the "rook" by English-speaking players, since it moves identically to the rook in Western chess.<ref name="ancient"/> Chinese players (and others) often call this piece a car, since that is one modern meaning of the character 車.
====Cannon====
[[Image:Xiangqi Cannon (Trad).svg|180px|The cannons|left]][[Image:XiangqiCannonJumpToCapture.png|thumb|147px|The long-range threat of the cannon]]
'''Cannons''' are labelled 砲 {{Audio|zh-pao4.ogg|''pào''|help=no}} ("[[catapult]]") for Black and [[Wikt:炮|炮]] ''pào'' ("cannon") for Red. The names are [[homophone]]s, though sometimes 炮 is used for both Red and Black. The 石 ''shí'' [[radical (Chinese characters)|radical]] of 砲 means "stone", and the 火 ''huǒ'' radical of 炮 means "fire". Both colours' pieces are normally referred to as cannons in English. The black piece is sometimes labelled [[Wikt:包|包]] bāo.
Each player has two cannons, which start on the row behind the soldiers, two points in front of the horses. Cannons move like chariots, any distance orthogonally without jumping, but can only capture by jumping a single piece of either colour along the path of attack. The piece over which the cannon jumps is called the 炮臺 (trad.) / 炮台 (simp.) ''pào tái'' ("cannon platform" or "screen"). Any number of unoccupied spaces, including none, may exist between the cannon, screen, and the piece to be captured. Cannons can be exchanged for horses immediately from their starting positions.<ref name="pieces"/>
====Soldier====
[[Image:Xiangqi Soldier (Trad).svg|180px|The soldiers|left]]
'''Soldiers''' (or '''pawns''') are labelled 卒 {{Audio|zh-zu2.ogg|''zú''|help=no}} ("pawn" or "private") for Black and 兵 {{Audio|zh-bing1.ogg|''bīng''|help=no}} ("soldier") for Red. Each side starts with five soldiers. Soldiers begin the game located on every other point one row back from the edge of the river. They move and capture by advancing one point. Once they have crossed the river, they may also move and capture one point horizontally. Soldiers cannot move backward, and therefore cannot retreat; after advancing to the last rank of the board, however, a soldier may still move sideways at the enemy's edge.<ref name="pieces"/> The soldier is sometimes called the "pawn" by English-speaking players, due to the pieces' similar movements.<ref name="ancient"/>

These approximate values<ref>{{cite book |last=Lau |first=H. T. |title=Chinese Chess |publisher=[[Tuttle Publishing]] |year=1985 |chapter=Values and Uses of the Pieces |pages=[https://archive.org/details/chinesechessintr0000lauh/page/28 28–30] |isbn=0-8048-3508-X |chapter-url=https://archive.org/details/chinesechessintr0000lauh/page/28 }}</ref> do not take into account the position of the piece in question (except the soldier in a general sense), the positions of other pieces on the board, or the number of pieces remaining. In what follows, “minor piece” will refer to horses and cannons, and "defensive piece", unless otherwise specified, will refer to the non-royal pieces that cannot cross the river, namely advisors and elephants.
Other common rules of assessment:
* A horse plus a cannon is generally better than two horses or two cannons.
* The chariot is not only the strongest piece, but it is also generally stronger than any combination of two minor pieces. When the relative values of both sides' pieces are approximately even, the side with more chariots generally has the advantage, especially when one side has a chariot and one side does not (Chinese: 有車壓無車). However, the chariot is not particularly strong in basic endgames: for example, chariot versus four defensive pieces is generally a draw, while if the offensive side instead has two horses or even three unadvanced soldiers it is a win.
* In the earlier stages, the cannon is stronger than the horse, because platforms are plentiful and the horse is often blocked by the multitude of pieces on the board. In the endgame, the horse is stronger as an attacking piece, not needing any platforms, but the cannon generally has better defensive abilities.
* The values of soldiers vary in different stages of the game. In the opening and the middlegame, the initiative and mobility of pieces often require sacrificing soldiers. In these stages, soldiers closer to the middle file are generally more valuable, since they can effectively join the offence. With few attacking pieces on the board, soldiers have more power and can cross the river more easily. In this stage, advanced soldiers are generally less powerful, since soldiers cannot move backward. In basic endgames, three soldiers starting on the 7th rank are approximately equal to a chariot: they can force a win against four defensive pieces or a horse/cannon plus two elephants, while instead a chariot cannot, and a chariot cannot force a win against three soldiers on the 7th rank when well-defended.
==Notation==
There are several types of notation used to record xiangqi games. In each case the moves are numbered and written with the same general pattern.
# (first move) (first response)
# (second move) (second response)
# ...
It is clearer but not required to write each move pair on a separate line.
===System 1===
The book ''The Chess of China'' describes a move notation method in which the ranks of the board are numbered 1 to 10 from closest to farthest away, followed by a digit 1 to 9 for files from right to left.<ref>Leventhal, Dennis A. ''The Chess of China''. Taipei, Taiwan: Mei Ya, 1978. ([http://www.getcited.org/pub/101996662 getCITED.org listing] {{webarchive |url=https://web.archive.org/web/20050226031808/http://www.getcited.org/pub/101996662 |date=February 26, 2005 }})</ref> Both values are relative to the moving player. Moves are then indicated as follows:
<code>[piece name] ([former rank][former file])-[new rank][new file]</code>
Thus, the most common opening in the game would be written as:
# 炮 (32)–35 {{pad|0}} 馬 (18)–37

|}
A notation system partially described in ''A Manual of Chinese Chess''<ref>Wilkes, Charles Fred. ''A Manual of Chinese Chess''. 1952.</ref> and used by several computer software implementations describes moves in relative terms as follows:
<code><nowiki>[single-letter piece abbreviation][former file][operator indicating direction of movement][new file, or in the case of purely vertical movement, number of ranks traversed]</nowiki></code>
The file numbers are counted from each player's right to each player's left.
In case there are two identical pieces in one file, symbols + (front) and – (rear) are used instead of former file number. Direction of movement is indicated via an operator symbol. A [[plus sign]] is used to indicate forward movement. A [[minus sign]] is used to indicate backward movement. A [[full stop|dot or period]] or [[equals sign]] is used to indicate horizontal or lateral movement. For a piece that moves diagonally (such as the horse or elephant), the plus or minus sign is used rather than the period.
Thus, the most common opening in the game would be written as:
# C2.5 H8+7
According to [[World Xiangqi Federation]] (WXF), in the case of [[doubled pawn|tripled, quadrupled, or quintupled]] soldiers (pawns), the S for soldier or P for pawn is omitted. Instead, the soldiers are numbered starting from the frontmost soldier, and this number replaces the usual piece abbreviation. The file number is given immediately after as usual.
Thus the notation to move the middle of a set of tripled soldiers on the 5th file to the 4th file would be:
# 25=4
In older books written in Chinese the system is the same, except that:
the names of the pieces are written in Chinese;
the name for the cannon on both sides is 炮;
the name for the horse on both sides is 馬;
forward motion is indicated with 進 (pronounced ''jìn'');
backward motion is indicated with 退 (''tuì'');
sideways motion is indicated with 平 (''píng'');
and numbers are written in Chinese either for both players or for just Black.
Thus, the most common opening in the game might be written as:
# 炮二平五 馬8進7
===System 3===
This system is unofficial and principally used by Western players.{{Citation needed|date=December 2012}} It is similar to [[algebraic notation (chess)|algebraic notation]] for Western chess. Letters are used for files and numbers for ranks. File "a" is on Red's left and rank "1" is nearest to Red. A point's designation does not depend on which player moves; for both sides "a1" is the lowest left point from Red's side.
<code><nowiki>[single-letter piece abbreviation][former position][capture indication][new position][check indication][analysis]</nowiki></code>
Pieces are abbreviated as in notation system 2, except that no letter is used for the soldier.
Former position is only indicated if necessary to distinguish between two identical pieces that could have made the move. If they share the same file, indicate which rank moves; if they share the same rank, indicate which file moves. If they share neither rank nor file, then the file is indicated.
Capture is indicated by "x". No symbol is used to indicate a non-capturing move.
Check is indicated by "+", double check by "++", triple check by "+++", and quadruple check by "++++". Checkmate is indicated by "#".
For analysis purposes, bad moves are indicated by "?" and good moves by "!". These can be combined if the analysis is uncertain ("!?" might be either but is probably good; "?!" is probably bad) or repeated for emphasis ("??" is a disaster).
Thus, the most common opening in the game would be written as:
# Che3 Hg8
=== Example ===
For example, the following game is tied with several others as the shortest possible xiangqi game (analogously to [[Fool's Mate]]), written in each of the three notations:

Black is mated and therefore loses. Red's cannon cannot be captured, and the advisor on e9 blocks both Black's general from escaping there and the advisor on d10 from unbecoming a platform for the cannon.
==Gameplay==
Because of the size of the board and the low number of long-range pieces, there is a tendency for the battle to focus on a particular area of the board.{{clarify|date=September 2015}}
===Tactics===
{{see also|Chess tactic}}
Xiangqi involves several tactics common to games in the chess family. Some common ones are briefly discussed here.
* In a ''[[Fork (chess)|fork]]'', one piece attacks two or more enemy pieces at once.
* A piece is ''[[Pin (chess)|pinned]]'' when it cannot move without exposing a more important piece to capture. Every piece except soldiers and advisors can pin, but only chariot pins exactly resemble pins in western chess; pins by other pieces in xiangqi take on many unique forms: Cannons can pin two pieces at once on one file or rank, horses can pin because they can be blocked, and generals can pin because of the "flying general" move rule. In pins by horses and elephants, the pinning piece never attacks the pinned piece, while in a pin by a cannon, only one of the pieces is directly attacked by the cannon. A general can only pin pieces to the enemy general, and the pinning general can never capture the pinned piece, since that would place it in check from the enemy general.
* A piece is ''[[Skewer (chess)|skewered]]'' when it is attacked and, by moving, exposes a less important piece to be captured. In contrast to pins, only cannons and chariots can skewer.

|}
* A ''[[discovered check]]'' occurs when an attacking piece moves so that it unblocks a line for a chariot, cannon, and/or horse to check the enemy general.
* A ''[[double check]]'' occurs when two pieces simultaneously threaten the enemy general. Unlike a Western chess double check, a double check in xiangqi may be blockable or, in one case, possibly met with a capture by a piece other than the general. The only blockable cases are either a chariot and cannon on the same file as the general, with the chariot acting as a screen for the cannon, two horses giving discovered check after another piece unblocks the attack from both, or a cannon using an enemy piece as a platform uncovered by a horse (see below). Double checks delivered by other means are not blockable. In one exceptional case, if a horse moves to give a double check by uncovering a cannon, and the cannon’s platform is an enemy chariot or defensive piece (advisor or elephant), the enemy chariot or defensive piece might be able to capture the horse, which removes the cannon’s platform at the same time. Otherwise, capturing either checking piece is insufficient to remove the threat, unless the general makes the capture.

* Unique to xiangqi is a ''triple check'', which arises in four combinations. In the first case of a cannon, a chariot or soldier, and a horse, the horse moves to give check, uncovering a double check from the chariot and the cannon. In the second, rarer case of a chariot or soldier and two horses, the chariot moves to give check, uncovering a double check from the two horses. In the third case of two cannons and two horses, one cannon may uncover a double check from the horses and act as a screen for the other cannon. Finally, a chariot or soldier can move to give check, uncovering a check from a horse while acting as a platform for a cannon to give another check. ''Quadruple check'' is also possible, arising with two horses, a chariot, and a cannon. Triple and quadruple check cannot be blocked or met by captures (again, unless the general makes the capture).

In contrast to the ubiquity of [[pawn chain]]s in western chess, soldiers typically do not support each other until the endgame, because from the initial position it takes a minimum of five moves of a soldier to allow mutual protection between two of them, and they are often prone to capture by other pieces.
Soldiers, horses, cannons and chariots can form up formations that protect each other. However, lining up chariots must be done with caution, as this risks losing one chariot to an enemy's inferior piece. Horses that support each other are called Linked Horses (Chinese: 連環馬), which is a relatively safe formation of the horses, though it can still be threatened with a soldier, a chariot plus another minor piece, or a piece blocking one of the horses thus making the protection one-sided.
It is common to use cannons independently to control particular ranks and files. Using a cannon to control the middle file is often considered vital strategy, because it pins pieces such as the advisors and elephants to the general, which in turn restrict their general’s movement. The two files adjacent to the middle file are also considered important and horses and chariots can be used to push for checkmate there.
Since the general is usually safest in its original position before the endgame phase, attacking the general commonly involves forcing the general out of its original position with check or with threats. Thus, specific points and formations are very important in xiangqi.
For an attacking (Red) horse, the most fatal points are c9 and g9 (Chinese: 臥槽馬), especially since without proper defence a quick mate can follow with an extra chariot or cannon.

|25}} Due to the pin of two pieces by the red cannon, Black's centroid horse has become a liability rather than an asset.
|}
For a cannon, one of the most fatal formations is the exposed cannon (Chinese: 空心炮), where the cannon directly controls the middle file with no other pieces between the cannon and the general. This formation is particularly dangerous since the defensive side cannot move any piece in front of the cannon; while with an extra cannon joining the attack, mate can follow on the spot, and with an extra rook, the offensive side can mount a double check (with the rook in front of the cannon) followed by a [[windmill (chess)|windmill]] (as when the check is blocked, the rook moving laterally discovers a new check from the cannon), often winning at least a piece afterwards. If the defensive side cannot chase the cannon away or capture it, it must move the general forward to avoid these threats, leaving the general vulnerable to attacks.
Another fatal formation, called the "cannon-controlled centroid horse" (Chinese: 炮鎮窩心馬, diagram at right), also requires particularly bad coordination of the enemy pieces. In the diagram, Black's "centroid horse" occupies the centre of the palace, blocking Black's own general and advisors, and being pinned to the general by the red cannon, cannot move. Black's cannon at e8 is also pinned to its own general; it too is unable to move and restricts the movement of Black's two elephants, making them unable to protect each other. Such a formation in the middlegame often produces deadly threats of smothered mates, while in the endgame, as in the diagram, Red's cannon cannot be chased away, rendering Black's general, advisors, cannon on e8, and horse all permanently immobilized. Even though Black is up a minor piece, Red has a clear win: The game concluded 41.Hg7 (forking the elephant and pinned cannon and creating a mating threat) Eg10 42.Hh9 Ci9 43.Hf8+ Cf9 (if not for the other black cannon, it is instant mate) 44.Hxg6, and Black resigned: Black's only active piece (the cannon on f9) is absolutely helpless to stop Red's horse and soldiers, which will soon invade the palace.
A common defensive configuration is to leave the general at its starting position, deploy one advisor and one elephant on the two points directly in front of the general, and to leave the other advisor and elephant in their starting positions, to the side of the general. In this setup, the advisor and elephant pairs support each other, and the general is immune from attacks by cannons. Losing any defensive pieces makes the general vulnerable to cannon attack, and the setup may need to be abandoned. The defender may move defensive pieces away from the general, or even sacrifice them intentionally, to ward off attack by a cannon.

Long sequences of checks leading to mate or gain of material are common both in chess compositions and in actual play. A skilled xiangqi player would often have to calculate several steps, or even tens of steps ahead for a forced sequence. In the diagram on the right, Black has an immediate mating threat which cannot be parried, forcing Red to check Black on every move. Although it requires 11 moves to mate, its general idea is clear: Induce a smothered check by sacrificing a chariot at the centre of the palace (e9), then force Black to open the centre file, enabling the Red general to assist the attack, and finally mate by facing generals.

|25}} The most common opening pair of moves
|}
Since the left and right flanks of the starting setup are symmetrical, it is customary to make the first move on the right flank. Starting on the left flank is considered needlessly confusing.{{citation needed|date=September 2015}}
The most common opening is to move the cannon to the central column, an opening known as 當頭炮 (trad.) / 当头炮 (simp.) ''dāng tóu pào'' or "Central Cannon". The most common reply is to advance the horse on the same flank. Together, this move-and-response is known by the rhyme 當頭炮，馬來跳 (trad.) / 当头炮，马来跳 (simp.) {{Audio|zh-dang1tou2pao4_ma3lai2tiao4.ogg|''dāng tóu pào, mǎ lái tiào''|help=no}}. The notation for this is "1. 炮 (32)–35, 馬 (18)–37", "1. C2.5 H8+7", or "1. Che3 Hg8" (diagram at right). After Black's 1. ...H8+7 (Hg8) response, the game can develop into a variety of openings, the most common being the 屏風馬 (trad.) / 屏风马 (simp.) or "Screen Horses (Defence)" in which Black develops the other horse to further protect their middle pawn (...H2+3 or ...Hc8) either immediately on their second move, or later when Black transposes the game into this opening.
Alternative common first moves by Black are developing either cannons (1. ...C8.5/1. ...Che8, or 1. ...C2.5/1. ...Cbe8); note that after either of these moves, taking the central soldier with the cannon (2. C5+4 or 2. Cxe7+) is a beginner's trap that impedes development and coordination of Red's pieces if Black plays correctly (for example, 1. Che3 Che8 2. Cxe7+?? Ade9 3. Hg3 Hg8 4. Ce5 Rh10 when Black develops the rook first, and the loss of Black's middle pawn actually enabled Black's horses to occupy the centre on the next moves).
Other common first moves by Red include moving an elephant to the central column (1. Ege3), advancing the soldier on the third or seventh file (1. c5), moving a horse forward (1. Hg3), and moving either cannon to the 4th or 6th (d- or f-) file (1. Chd3 or 1. Chf3). Compared to the Central Cannon openings, these openings are generally less restricted by theory.
General advice for the opening includes rapid development of at least one chariot and putting it on open files and ranks, as it is the most powerful piece with a long attack range. There is a saying that only a poor player does not move a chariot in the first three moves (Chinese: 三步不出車，必定要輸棋); however this is not to be taken literally, and is in fact often violated in modern Xiangqi games.{{Citation needed|date=December 2012}} Attacking and defending the centre, especially the central soldiers / central pawns, are common themes in the opening, hence the Central Cannon openings. Usually, at least one horse should be moved to the middle in order to defend the central soldier; however undefended central soldiers can also become "poisoned pawns" in the early moves, especially if the attacking side does not have an immediate follow-up to retain the pressure on the central file.
===Middlegame strategy===
Xiangqi strategy shares common themes with chess, but has some differences:
* Occupying the centre is relatively less important in xiangqi, but controlling and attacking the middle file is still one of the vital themes. Since the middle file is often well defended, players would then seek to mount an offense on either of the flanks on the enemy side, especially when the defense of one flank is neglected.
* The significance of pawn formation in xiangqi and chess are different. In xiangqi, soldiers (pawns) are often pushed to avoid blocking their own horses, and it is uncommon for them to defend each other (in contrast with a Western chess [[pawn chain]]). Successfully getting a soldier to cross a river as an attacking force can often tilt the scales of the middlegame by a large margin.
* In high-level play, the initiative is highly important, and a minor mistake can doom a game.
* Sacrifices are common in xiangqi, however they are more often tactical rather than positional. Usually, at most a minor piece is sacrificed for positional advantages, or a semi-tactical attack.
Like in chess, xiangqi piece values depend highly on the position on the board. The following study from Volume 42 of the Elegant Pastime Manual, dating from the Ming Dynasty, illustrates this dramatically. It is Red to play and win.<ref>{{Cite web |last=Ping |first=Jim |date=January 22, 2021 |title=The Value of the Pieces in Xiangqi |url=https://www.xiangqi.com/articles/the-value-of-the-pieces-in-xiangqi-chinese-chess |access-date=February 20, 2023 |website=Xiangqi.com}}</ref>

In this position, Red is up two soldiers and a cannon but Black threatens seemingly unstoppable mate with ...Rf1#, since 1.Ec5? Ad8! renews the mate threat. Note that the red chariot is nearly useless, having only two legal moves, in stark contrast to the very active black chariot. However, Red averts the checkmate by sacrificing both the cannon and chariot: 1.Ca10+!! Hxa10 2.Ea3! Rxa1 (or the chariot is lost, since the general protects the elephant on e3, which in turn guards g1, and the red horse guards e2) 3.Eec1:

Despite the substantial sacrifice of material by Red, Black's chariot has now become useless as it is permanently immobilized by the red elephants and horse; the red general prevents the black soldier on g2 from moving laterally to free the chariot (for example 3...g1 4.Gf2). Black's horse similarly has no safe move due to the red soldier on c8, which also, along with the soldier on f9, prevents the black general from attacking the soldier on f9 from the behind. In addition, the black soldier on g6 is undefended and has no safe move, so Red can win it by pushing the soldier on c4 to c6 and moving it laterally to the g-file, after which the position is effectively an endgame of three soldiers against two advisers, an easy win for Red (see [[#Soldier (pawn) endgames|below]]) despite being down a chariot for three soldiers.
===Endgame===
Though xiangqi endgames require remarkable skill to be played well, there are a number of widely known book wins and book draws. Without a counterpart to [[pawn promotion]], xiangqi endgames instead focus more directly on forcing checkmate or stalemate, and in this regard resemble [[pawnless chess endgame]]s. Since stalemate is a loss for the stalemated player instead of a draw, most book draws in xiangqi are due to [[fortress (chess)|fortresses]], with a few draws due to [[insufficient material]].
A general rule in xiangqi endgames for the advantageous side is that, when there's less material on the board, do not trade pieces easily, as with fewer attacking pieces on the board, defending is easier (in contrast to Western chess, where it is almost always advantageous to trade pieces when up on material). Hence, if a certain type of endgame can transpose, by trading pieces, into another type of endgame which is a book win, then this endgame itself is a book win.

Red wins with either side to move.
|}
Inducing [[zugzwang]] is a crucial theme in winning simple endgames, and almost exclusively in simple endgames. In the general + soldier vs general endgame shown on the right, Red's first main goal is to occupy the middle file. Red wins with 1. Gd1, a waiting move, and Black is in zugzwang. Black must proceed with 1. ...Ge8, as 1. ...Ge10 instantly loses after 2. f9#. After 1. ...Ge8 2. f9 Gf8 3. e9 Ge8 4. d9 Gf8 5. Ge1, Red's general successfully occupies the middle file. The game would conclude with 5. ...Gf9 6. e9+, and regardless of Black's reply, 7. Ge2# (stale)mates Black.

Reciprocal zugzwang: Whoever moves first loses.
|}
Reciprocal zugzwang is possible, but very rare and usually seen in endgame compositions. In this endgame shown on the right, whoever moves loses, since when either of the two generals moves to an open d- or f- file, it threatens unstoppable mate, while the player to move only helps the enemy general occupy one of the files. For instance, Red can only move their two soldiers if he is to move. Moving the f-(or d-)soldier allows the enemy general to occupy the f-file(d-file). Even if 1. fe9+ Gf10 2. d10, when Red threatens mate in 1, Black still mates immediately with either 2. ...fe2# or 2. ...f1#.

* A soldier, as long as it does not reach the opposite rank, wins against a bare general easily. With any extra defensive piece on the defensive side, it is a draw; however, soldier vs advisor requires skill to play well. Any number of soldiers on the opposing back rank are also a draw due to insufficient material.
* Two unadvanced (i.e., on the 6th or 7th ranks) soldiers win against the following combinations: Two advisors, two elephants, a bare horse/cannon. Generally a draw against one advisor plus one elephant, or a horse/cannon plus a defending piece.
* Three unadvanced soldiers win against the following combinations: All 4 defensive pieces (2 advisors plus 2 elephants, Chinese: 士象全), a horse plus two advisors/two elephants, a cannon plus two elephants.

* A horse plus an advanced soldier(on the 8th or 9th rank) draws against either combination of 3 defensive pieces, but defending requires precise positions.
* A horse plus a soldier on the 10th rank wins against two advisors, or one advisor plus one elephant. This combination draws against 2 elephants.
* A horse plus two soldiers can win against one minor piece + one advisor + two elephants. With an extra advisor on the defensive side, it is a book draw.

* A bare cannon, or a cannon with elephants, cannot win against a bare general due to insufficient material. Cannons without other offensive pieces need defensive pieces to act as platforms, especially the advisor, since the advisor can act as a platform on any of the three central files, while an elephant can only act as a platform on the centermost file.
* A cannon needs only one advisor to win against two advisors, or a single elephant. Meanwhile, even with all 4 defensive pieces, it is a book draw against two elephants, one advisor + one elephant, one soldier + one advisor, or any minor piece.
* A cannon with all 4 defensive pieces needs at least an extra soldier to win against 4 defensive pieces. A bare cannon with a soldier on the 6th rank wins against any combination of 2 defensive pieces.
* A cannon + 4 defensive pieces + 2 unadvanced soldiers generally draw against one minor piece + 4 defensive pieces. But if the defensive side lacks a single piece, it is a book win.

====Horse+Cannon endgames====
This type of endgame is considered one of the more complex endgames. Commonly known book wins and book draws are:
* Horse + Cannon + 4 defensive pieces vs a minor piece vs 4 defensive pieces: A win if the minor piece is a horse (the attacking side does not need all 4 defensive pieces to win), a draw if it is a cannon.
* With the same combination of the two minor pieces and all 4 defensive pieces on both sides, one needs two extra soldiers for a book win.
* If both sides have 2 minor pieces and 4 defensive pieces, and the advantegeous side only has one extra soldier, then regardless of the combination of the two minor pieces, it is a book draw.

Single chariot endgames:
* A single chariot generally cannot win against 4 defensive pieces, but with 3 or fewer defensive pieces, it is a forced win.
* Chariot vs one minor piece plus 2 defensive pieces: A win if the 2 defensive pieces are not the same, or if the combination is horse + two advisors. If the defensive side has horse + two elephants, a specific fortress is required to draw.
* Chariot vs one minor piece plus 3 defensive pieces: A draw.
* Chariot vs two minor pieces with no defensive pieces: A draw, but requires good defensive positions.
Chariot + soldiers (unadvanced):
* Chariot + soldier, with sufficient defensive pieces on their own side, wins against a chariot plus an advisor, a chariot plus two elephants, or a chariot plus a soldier.
* Chariot + soldier wins against any 2 minor pieces + 2 advisors. This combination also wins against horse + 4 defensive pieces, but not cannon + 4 defensive pieces.
* Chariot + soldier vs 2 unadvanced soldiers + 4 defensive pieces: If the offensive side has no defensive piece, it is a draw since the 2 enemy soldiers can still be a formidable force. If the offensive side has one advisor, it is a win.
* Chariot + 2 soldiers cannot force a win against chariot + 4 defensive pieces. In this endgame, both attacking and defending require great skill.
Chariot + horse:
* A chariot plus a horse needs one advisor on their own side to win against a chariot plus two advisors.
* Chariot + horse vs chariot + two elephants: With enough defensive pieces for the attacking side, it is generally a win if the move limit is not taken into consideration.
Chariot + cannon:
* A chariot plus a cannon cannot win against a bare chariot, as long as the defending chariot occupies the middle file. However, with any extra defensive piece on the attacking side, it is a win.
* Chariot + cannon + 2 advisors would win against chariot + two elephants.
* Chariot + cannon + 4 defensive pieces vs chariot + 4 defensive pieces: Draw.
Two chariots:
* Two chariots vs chariot + 4 defensive pieces: A draw with good defensive positions.
* Two chariots vs chariot + minor piece + 2 defensive pieces: The only drawing combination is chariot + cannon + 2 advisors.
* Two chariots vs 2 minor pieces + 4 defensive pieces: A win if the 2 minor pieces are 2 horses.
==History==
[[File:二龍出海势.png|thumb|A picture of xiangqi in the Southern Song dynasty]]
A game called ''xiangqi'' was mentioned as dating to the [[Warring States period]]; according to the first-century-BC text ''[[Shuo Yuan]]'' (說苑/说苑), it was one of [[Lord Mengchang of Qi]]'s interests. However, the rules of that game are not described, and it was not necessarily related to the present-day game.<ref>[http://www.banaschak.net/schach/origins.htm "Facts on the Origin of Chinese Chess"] {{Webarchive|url=https://web.archive.org/web/20110723023019/http://www.banaschak.net/schach/origins.htm |date=2011-07-23 }}. Banaschak.net. Retrieved on 2011-10-01.</ref> [[Emperor Wu of Northern Zhou]] wrote a book in AD 569 called ''[[Xiang Jing]]''. It described the rules of an astronomically themed game called ''[[Northern Zhou Xiangxi|xiangxi]]'' ({{Lang|zh-hant|象戲}}). The word ''xiàngqí'' 象棋 is usually translated as "elephant game" or "figure game", because the [[Chinese character]] 象 means "elephant" and "figure"; it originated as a stylized drawing of an elephant, and was used to write a word meaning "figure", likely because the [[Chinese characters#Phonetic loans|two words were pronounced the same]].
For these reasons, Murray theorized that "in China [chess] took over the board and name of a game called 象棋 in the sense of 'Astronomical Game', which represented the apparent movements of naked-eye-visible astronomical objects in the night sky, and that the earliest Chinese references to 象棋 meant the Astronomical Game and not Chinese chess". Previous games called xiàngqí may have been based on the movements of sky objects. However, the connection between 象 and [[astronomy]] is marginal, and arose from constellations being called "figures" in astronomical contexts where other meanings of "figure" were less likely; this usage may have led some ancient Chinese authors to theorize that the game 象棋 started as a simulation of astronomy.{{Citation needed|date=December 2012}}
[[File:Song Dynasty Chinese chess set.JPG|thumb|right|Xiangqi game pieces dated to the [[Northern Song dynasty]]]]
To support his argument, Murray quoted an old Chinese source that says that in the older xiangqi (which modern xiangqi may have taken some of its rules from) the game pieces could be [[shuffling|shuffled]], which does not happen in the modern chess-style xiangqi.<ref>''[[A History of Chess]]'', p.122, footnote 12: "In the biography of [[Lü-Ts'ai]]. The Emperor [[Emperor Taizong of Tang|T'ai-Tsung]] (627–650) was puzzled by the phrase 太子洗馬 ''t'ai-tze-si-ma'' ("the [[crown prince]] washes the horses") in the 周武帝三局象經 ''Zhou Wudi sanju xiangjing'' ("Zhou Wudi's three games in the Xiangjing"); "to wash the [[dominoes]]" means to shuffle them in modern Chinese; ''ma'' or "horse" is used for the pieces in a game. The phrase probably meant "the crown-prince shuffles the men". He consulted [[Yün-Kung]], who had known the phrase as a young man but had forgotten it, and then Lü-Ts'ai. The latter, after a night's consideration, explained the point, and recovered the method of play of the astronomical game and the actual position."</ref> Murray also wrote that in ancient China there was more than one game called xiangqi.<ref>''A History of Chess'', p.122: The 32nd book of the history of the [[T'ang dynasty]] (618–907) said that [[Emperor Wu of Northern Zhou|Wu-Ti]] wrote and expounded a book named ''San-kü-siang-king'' (Manual of the three xiangqi's).</ref> Murray also even supposed that [[chaturanga]] from India influenced the formation of present-day xiangqi.<ref>{{cite book

An alternative hypothesis to Murray's is that xiangqi was patterned after the array of troops in the [[Warring States period]]. [[David H. Li]], for example, argues that the game was developed by [[Han Xin]] in the winter of 204 BC-203 BC to prepare for an upcoming battle.<ref>This theory is propounded in ''The Genealogy of Chess''</ref> His theories have been questioned by other chess researchers, however.<ref>{{cite web|url=http://www.banaschak.net/schach/ligenealogyofchess.htm|title=A story well told is not necessarily true – being a critical assessment of David H. Li's 'Genealogy of Chess'|author=Peter Banaschak|website=Banaschak.net|access-date=2011-10-01}}</ref> The earliest description of the game's rules appears in the story "Cén Shùn" (岑順) in the collection ''[[Xuanguai lu]]'' (玄怪錄), written by [[Niu Sengru]] in the middle part of the [[Tang dynasty]].
Xiangqi is the same as it is today from [[Southern Song dynasty]].
[[Janggi]] of [[Korean Peninsula]] originates from Xiangqi.
With the popularization of xiangqi, many different schools of circles and players came into prominence, many books and manuals on the techniques of playing the game were also published, they played an important role in popularizing xiangqi and improving the techniques of play in modern times. With the economic and cultural development during the [[Qing dynasty]], xiangqi entered a new stage. A Western-style ''[[Encyclopedia of Chinese Chess Openings]]'' was written in 2004.<ref name="ecco2004">{{cite web|title=中国象棋开局编号——ECCO 2004|url=http://www.xqbase.com/ecco/ecco_intro.htm|website=xqbase.com|access-date=16 February 2018}}</ref>

===Tournaments and leagues===
Although xiangqi has its origin in Asia, there are xiangqi leagues and clubs all over the world. Each European nation generally has its own governing league; for example, in Britain, xiangqi is regulated by the United Kingdom Chinese Chess Association. Asian countries also have nationwide leagues, such as the Malaysia Chinese Chess Association.{{citation needed|date=July 2016}}

===Rankings===
The Asian Xiangqi Federation (AXF) and its corresponding member associations rank players in a format similar to the [[Elo rating system]] of chess. According to the XiangQi DataBase, the top-ranking female and male players in China, as of June 2012, were [[Tang Dan]] and Jiang Chuan, with ratings of 2529 and 2667, respectively.<ref>{{cite web|title=2012 First half(Female) Player Rating|url=http://www.01xq.com/xqplayer/xqrating.asp?y=2012&m=1&s=1|work=01xq.com – Event Game Player Opening|publisher=01xq.com|access-date=4 June 2012|author=Staff|date=June 2012}}</ref><ref>{{cite web|title=2012 First half(Male) Player Rating|url=http://www.01xq.com/xqplayer/xqrating.asp|work=01xq.com – Events Game Player Opening|publisher=01xq.com|access-date=4 June 2012|author=Staff|date=June 2012}}</ref> Other strong players include Zhao GuanFang (female), [[Xu Yinchuan]] (male), Lu Qin (male), and Wang LinNa (female).{{Citation needed|date=December 2012}}
The Asian Xiangqi Federation also bestows the title of grandmaster to select individuals around the world who have excelled at xiangqi or made special contributions to the game. There are no specific criteria for becoming a grandmaster and there are only approximately 100 grandmasters as of 2020.<ref>{{Cite web|title=XiangQi Master Database|url=http://wxf.ca/xq/xqdb/xqdb_index.html|access-date=2021-01-22|website=wxf.ca}}</ref> The titles of grandmaster is bestowed by bodies such as the AXF and the Chinese Xiangqi Association (CXA).<ref>{{cite web |url=http://www.chessvariants.org/chinfaq.html#question22 |last1=Leary |first1=Stephen |last2=Bodlaender |first2=Hans |author-link2=Hans L.

===Computers===
The [[Game complexity|game-tree complexity]] of xiangqi is approximately 10<sup>150</sup>; in 2004 it was projected that a human top player would be defeated before 2010.<ref>Yen, Chen, Yang, Hsu, 2004, [http://www.csie.ndhu.edu.tw/~sjyen/Papers/2004CCC.pdf Computer Chinese Chess] {{webarchive |url=https://web.archive.org/web/20070614111609/http://www.csie.ndhu.edu.tw/~sjyen/Papers/2004CCC.pdf |date=June 14, 2007 }}.</ref> Xiangqi is one of the more popular computer-versus-computer competitions at the [[Computer Olympiad]]s.<ref>Results of the Computer Olympiad competitions are found [[Computer Olympiad#Chinese chess|here]]</ref>
Computer programs for playing xiangqi show the same development trend as has occurred for international chess: they are usually console applications (called engines) which communicate their moves in text form through some standard protocol. For displaying the board graphically, they then rely on a separate [[graphical user interface]] (GUI). Through such standardization, many different engines can be used through the same GUI, which can also be used for automated play of different engines against each other. Popular protocols are UCI ([[Universal Chess Interface]]), UCCI (Universal Chinese Chess Interface), Qianhong (QH) protocol, and [[WinBoard]]/XBoard (WB) protocol (the latter two named after the GUIs that implemented them). There now exist many dozens of xiangqi engines supporting one or more of these protocols, including some commercial engines.{{Citation needed|date=December 2012}}
==Variations==
'''Blitz chess''' <br />Each player only has around 5–10 minutes each.
'''[[Manchu chess]]'''<br>Invented during the [[Manchu]]-led [[Qing dynasty]]. Red horses, cannons, and one of the chariots are absent, but the remaining chariot can be played as horses and cannons as well.
'''Supply chess''' <br />Similar to the Western chess variant [[Bughouse chess]], this variant features the ability to re-deploy captured pieces, similar to a rule in [[shogi]]. Four players play as two-person teams in two side-by-side games. One teammate plays Black and other plays Red. Any piece obtained by capturing the opponent's piece is given to the teammate for use in the other game. These pieces can be deployed by the teammate to give him an advantage over the other player, so long as the piece starts on the player's own side of the board and does not cause the opponent to be in check.
'''Formation''' <br />Similar to [[Fischer Random Chess]], one player's pieces are placed randomly on one side of the river, except for the generals and advisors, which must be at their usual positions, and the elephants, which must start at two of the seven points they can normally reach. The other player's pieces are set up to mirror the first's. All other rules are the same.
'''[[Banqi]]''' <br />This variation is more well known in [[Hong Kong]] than in mainland China. It uses the xiangqi pieces and board, but does not follow any of its rules, bearing more of a resemblance to the Western game [[Stratego]] as well as the Chinese game [[Luzhanqi]].
==Variations played with special boards or pieces==
There are many versions of three-player xiangqi, or ''san xiangqui'', all played on special boards.
'''[[San Guo Qi]]''' <br />"Game of the Three Kingdoms" is played on a special hexagonal board with three xiangqi armies (red, blue, and green) vying for dominance. A Y-shaped river divides the board into three gem-shaped territories, each containing the grid found on one side of a xiangqi board, but distorted to make the game playable by three people. Each player has eighteen pieces: the sixteen of regular xiangqi, plus two new ones that stand on the same rank as the cannons. The new pieces have different names depending on their side: ''huo'' ("fire") for Red, ''qi'' ("flag") for Blue, and ''feng'' ("wind") for Green. They move two spaces orthogonally, then one space diagonally. The generals each bear the name of a historical Chinese kingdom—Shu for Red, Wei for Blue, and Wu for Green—from China's [[Three Kingdoms]] period.<ref name=3King>{{cite web

'''[[Game of the Three Friends|San You Qi]]''' <br />"Three Friends Chess" was invented by Zheng Jinde from [[She County, Anhui|Shexian]] in the [[Anhui]] province during the reign of the [[Kangxi Emperor]] of the [[Qing dynasty]] (1661–1722). It is played on a Y-shaped board with a full army of xiangqi pieces set up at the end of each of the board's three wide radii. In the centre of the board sits a triangular zone with certain features, such as ocean, mountain, or city walls, each of which is impassable by certain pieces. Two of an army's five soldiers are replaced by new pieces called ''huo'' ("fire") pieces, which move one space diagonally forward. Two ''qi'' ("flag") pieces are positioned on the front corners of the palace; they move two spaces forward inside their own camp, and then one space in any direction inside an enemy camp.<ref name="San Xiangqi" />
'''Sanrenqi''' <br />"Three Men Chess" is a riverless, commercial variant played on a cross-shaped board with some special rules, including a fourth, neutral country called ''Han.'' Han has three Chariots, one Cannon, and one General named "Emperor Xian of Han", but these pieces do not move and do not belong to any of the players until a certain point in the game when two players team up against the third player. At that point the third player gets to also control Han.<ref name="San Xiangqi" />
'''Si Guo Qi''' <br />"Four Kingdoms Chess" is also played on a riverless, cross-shaped board, but with four players. Because there are no rivers, elephants may move about the board freely.<ref name="San Xiangqi" />
'''[[Game of the Seven Kingdoms|Qi Guo Xiang Qi]]''' <br />"Game of the Seven Kingdoms" is based symbolically on the Warring States Period.
