Xiangqi

"Chinese chess" redirects here. For , see .

Xiangqi (Chinese: 象棋; Pinyin: xiàngqí; Wade-Giles: hsiang⁴-ch'i²; [listen] ([Media helphelp]·[info])), is a two-player Chinese game in a family of strategic board games of which Western chess, Indian chaturanga, Japanese shogi, and the more similar Korean janggi are also members. Xiangqi is native to China and is therefore commonly called Chinese chess. The first character [[Wikt:象|象]] xiàng here has the meaning "image" or "representational", hence Xiangqi can be literally translated as "representational chess". The second character, [[Wikt:棋|棋]], is a general term also used in the name 西洋棋 xīyáng qì — "Western chess".

Chinese chess has a long history. Though its precise origins have not yet been definitely confirmed, the earliest indications reveal the game was played as early as the 4th century BC in China. (see History below).

Xiangqi is one of the most popular board games in the world. Distinctive features of Xiangqi include the unique movement of the pao ("cannon") piece, a rule prohibiting the generals (similar to chess kings) from facing each other directly, and the river and palace board features, which restrict the movement of some pieces.

Rules of the game

Board

Xiangqi is a common pastime in Chinese cities such as Beijing

Xiangqi is played on a board that is 9 lines wide by 10 lines long. In a manner similar to the game go, the pieces are played on the intersections, which are known as points. The vertical lines are known as files, while the horizontal lines are known as ranks. With a few awkward substitutions, it is possible to play this game using a standard chess set.

Centered at the first through third ranks of the board is a square zone also mirrored in the opponent's territory. The three point by three point zone is demarcated by two diagonal lines connecting opposite corners and intersecting at the center point. This area is known as 宮 gōng ([listen]), the palace or fortress.

Dividing the two opposing sides (between the fifth and sixth ranks) is 河 hé, the river. The river is often marked with the phrases 楚河 chǔ hé ([listen]), meaning "Chu River", and 漢界 (in Traditional Chinese) or 汉界 (in Simplified Chinese) hàn jiè ([listen]), meaning "Han border", a reference to the Chu-Han War. Although the river provides a visual division between the two sides, only a few pieces are affected by its presence: soldiers are promoted after crossing, and elephants cannot cross the river.

The starting points of the soldiers and cannons are marked with a small cross.

Pieces

The two players take command of pieces on either side of the river. One player's pieces are usually painted red (or, less commonly, white), and the other player's pieces are usually painted black (or, less commonly, blue or green). Which player moves first has varied throughout history, and also varies from one part to another of China. Some xiangqi books state that the black side moves first; others state that the red side moves first. Also, some books may refer to the two sides as north and south; which direction corresponds to which color also varies from source to source.

Modern xiangqi pieces are represented by disks marked with a Chinese character identifying the piece and painted in a color identifying to which player the piece belongs. Modern pieces are usually made with plastic, though some sets use pieces made of wood, and more expensive sets may use pieces made of jade. In more ancient times, many sets were simple unpainted woodcarvings; thus, to distinguish between the pieces of the two sides, most corresponding pieces use characters that are similar but vary slightly between the two sides.

General/Marshal

General and advisors

The generals are labelled with the Chinese character 將 (trad.) / 将 (simp.) jiàng ([listen]) (general) on the black side and 帥 (trad.) / 帅 (simp.) shuai ([listen]) (marshal) on the red side. These pieces are equivalent to the kings of Western chess. Legend has it that originally the pieces were known as emperors, but when an emperor of China heard about the game, he executed two players for "killing" or "capturing" the emperor piece. Future players called them generals instead.

The general starts the game at the midpoint of the back edge (within the palace). The general may move one point either vertically or horizontally but the general may not move diagonally. The general cannot leave the palace under any circumstances; thus, the general can only move to and stay on the 9 points within the palace.

When a general is threatened by an enemy piece, the general is said to be "in check." When the general is in check and unable to escape check on the player's move, it is said to be checkmated, and the player loses the game. A player also loses when his general is not in check, but he can make no legal move that doesn't put the general in check; a stalemate rule does not exist.

A player cannot make any move that would leave the two generals facing one another on the same file with no other pieces placed in between. In other words, a clear line of sight can never exist between the two generals. This is a very important feature of the game and is often forgotten by new players of the game. It is important because the general often plays a role in enforcing checkmate, especially when many of the other pieces have been taken and the board is wide open. Indeed, checkmate remains possible as long as a player retains the general and any single piece (with the exception of a cannon), even a soldier, that can cross the river.

Advisor

The advisors (also known as guards or ministers, and less commonly as assistants, mandarins, or warriors) are labelled 士 shì ([listen]) ("scholar", "gentleman", "officer") for black and 仕 shi ([listen]) ("scholar", "official") for red. It is perhaps worth noting that the two Japanese readings of 士 are samurai, and shi as in bushido.

While their origin is probably the same as that of the queen in Western chess, their powers are decidedly distinct from those of the queen.

The advisors start to the sides of the general. They move one point diagonally and may not leave the palace. This effectively means they can only move to five of the points within the palace. They serve to protect the general.

Elephant

The elephants are labelled 象 xiàng (elephant) for black and 相 xiàng (minister) for red. They are located next to the advisors. These pieces move exactly two points diagonally and may not jump over intervening pieces. They may not cross the river; thus, they serve as defensive pieces. There are only seven possible points on the board to which they can move.

Because of an elephant's limited movement, it is easily trapped. A chariot (see below) can trap one just by moving to a space where all spaces available to the the elephant are threatened. Since one elephant cannot easily stand by itself, it depends upon the other for protection.

The Chinese characters for "minister" and "elephant" are homonyms ([listen]) and both have alternative meanings as "appearance" or "image".

Horse

The red horse may take the black horse, but the black horse cannot take the red horse because its movement is obstructed by another piece

Green moves are legal; red ones are illegal because another piece is obstructing the movement of the horse

The horses are labelled 馬 mǎ ([listen]) for black and 傌 mà ([listen]) for red in sets marked with Traditional Chinese characters and 马 mǎ ([listen]) for both black and red in sets marked with Simplified Chinese characters. They begin the game next to the elephants. It moves one point vertically or horizontally and then one point diagonally away from its former position. It is important to note that the horse does not jump. Thus, if there were a piece lying on a point one point away horizontally or vertically from the horse, then the horse's path of movement is blocked and it is unable to move in that direction. Note, however, that a piece two points away horizontally or vertically or a piece a single point away diagonally would not impede the movement of the horse. The diagram on the left illustrates the horse's movement.

Since horses can be blocked, it is sometimes possible to trap the opponent's horse. It is possible for one player's horse to attack the opponent's horse while the opponent's horse is blocked from attacking, as seen in the diagram on the right.

Chariot

The chariots are labelled 車 for black and 俥 for red in sets marked with Traditional Chinese characters and 车 for both black and red in sets marked with Simplified Chinese characters. All three of these characters are pronounced as jū ([listen]) in the game, although the everyday pronunciation of all three is chē ([listen]). Capturing and moving in a straight line either horizontally or vertically, the chariot moves and captures vertically and horizontally any distance. The chariots begin the game on the points at the corners of the board. It is considered to be the strongest piece in the game.

Cannon

The cannons are labelled 砲 pào ([listen]) for black and 炮 pào ([listen]) for red. Alternatively, both can be 包 bāo ([listen]).

[[Wikt:包|包]] bāo means "package". [[Wikt:砲|砲]] pào means a "catapult" for hurling boulders. [[Wikt:炮|炮]] pào means "cannon" (its pre-gunpowder meaning being "roast" [link]).

In Xiangqi, each player has two cannons. The cannons start on the row behind the soldiers, two points in front of the horses. Cannons move like the chariots, horizontally and vertically, but capture by jumping exactly one piece (whether it is friendly or enemy); it cannot capture by jumping more than one piece, or without jumping a piece. When capturing, the cannon is moved to the point of the captured piece. The piece over which the cannon jumps is called the 包台 bāo tái — "cannon platform". Any number of unoccupied spaces may exist between the cannon and the cannon platform, or between the cannon platform and the piece to be captured, including no spaces (the pieces being adjacent) in both cases. Cannons are powerful at the beginning of the game when platforms are plentiful, but lose value rapidly with attrition.

Soldier

Each side has five soldiers, labelled 卒 zú ([listen]) for black and 兵 bīng ([listen]) for red. Soldiers are placed on alternating points, 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 may not move two points on their first move, and there is no en passant rule, as in a Western Chess. When soldiers reach the enemy's edge of the board they are not promoted. Like pawns, soldiers may not retreat at any time; however, they may still move sideways at the enemy's edge.

Approximate relative values of the pieces

Piece	Point(s)
Soldier before crossing the river	1
Soldier after crossing the river	2
Advisor	2
Elephant	2
Horse	4 - 5
Cannon	4 - 5
Chariot	9

It is to be noted that these are advisory values and that the piece values do not take into account positional advantages. Often a piece is more powerful at a certain intersection as compared to another intersection. The chariot at the corner in the beginning of the game is not very useful, but it can be moved to points where it affects the game much more. Also, the value of a cannon drops as the game goes on due to having fewer hurdles for use in capturing, while the value of the horse increases slightly due to fewer obstructions. It should be pointed out that often, players will value a cannon on or exceeding the level of a chariot due to its unique attack style. The same can be applied to the horse.

Ending the game

"Jiāngjūn!"

The game ends when one player successfully checkmates the other player — that is, when one player successfully threatens the opposing general with a piece and the player with the threatened general has no legal moves which would prevent the general from being threatened.

In Chinese, to say check, one says 將 (trad.) / 将 (simp.) jiāng ([listen]), and to say checkmate, one says 將軍 (trad.) / 将军 (simp.) jiāngjūn ([listen]).

In Western chess, if a player's king is not in check and the player has no legal moves available, the game ends in stalemate and a draw. This is not the case in xiangqi; in xiangqi, the player who has no legal moves loses the game.

In Western chess, perpetual check or an excessive number of repetitions of position can result in a draw. This is not the case in xiangqi, wherein if a position is being repeated:

The side that perpetually checks with one piece or several pieces will be ruled to lose under any circumstances unless he stops the perpetual checking.
The side that perpetually chases with one piece will be ruled to lose under any circumstances unless he stops the perpetual chasing.
If one side perpetually checks and the other side perpetually chases, the perpetually checking side has to stop or be ruled to lose.
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 and both persist in not making an alternate move, the game can be ruled as a draw.

Notation

Notational system 1

The book The Chess of ChinaLeventhal, Dennis A. The Chess of China. Taipei, Taiwan, Republic of China: Mei Ya, 1978. ([getCITED.org listing]) describes a notational system of absolute positional references 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. Both values are relative to the moving player. Moves are then indicated as follows:

[piece name] ([former rank][former file])-[new rank][new file]

Thus, the most common opening in the game would be written as:

1. 炮 (32)–35, 馬 (18)–37

Notational system 2

A notational system partially described in A Manual of Chinese ChessWilkes, Charles Fred. A Manual of Chinese Chess. 1952. and used by several computer software implementations describes positions in relative terms as follows:

[single-letter piece abbreviation][former file][operator indicating direction of movement][new file, or in the case of purely vertical movement, new rank]

The file numbers are counted from each player's right to each player's left.

The initials are as follows:
Piece Initial(s)
Advisor A
Cannon C
Chariot R (for Rook, because using C would conflict with the letter for Cannon)
Elephant E
General G or K (for King)
Horse H
Soldier S or P (for Pawn)

Direction of movement is indicated via an operator symbol. A plus sign is used to indicate forward movement. A minus sign or hyphen is used to indicate backwards movement. A dot or period or equal sign is used to indicate horizontal or lateral movement. If a piece (such as the horse or elephant) simultaneously moves both vertically and horizontally, then the plus or minus sign is used rather than the period.

Thus, the most common opening in the game would be written as:

1. C2.5 H8+7

Gameplay and strategy

The long-range threat of the cannon

Xiangqi plays faster than Western chess for several reasons. First, the barrier of pawns is reduced dramatically. Second, the cannons jump to capture, making them a long-range threat early in the game. In addition, since the general is confined to only moving within the palace, it can be checkmated more easily unless it is protected by other pieces.

While in Western chess, the battle between opposing sides is concentrated in the middle few rows for the bulk of the game, this is not the case in xiangqi. The board is bigger than the Western chessboard while the number of pieces is the same (resulting in less crowding), and there are not as many powerful pieces with long-range moves. Because of this, it can take time to move one's army of pieces from place to place on the board, and there is a tendency for the battle to focus on a particular area of the board. Common strategies such as forking with knight (horse in this case), pinning with rook (chariot, sometime cannon and general can also pin) are also applicable in here.

Usually, the soldiers do not support each other, so the concept of pawn structure does not play such a heavy role as in Western chess.

Defensively, a common configuration is to leave the general at his 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 the other elephant in their starting positions, to the side of the general. In this setup, the paired-up advisors and elephants support each other, and the general is immune from attacks by cannons. However, with the loss of a single advisor or elephant, the general becomes vulnerable to cannons, and this setup may need to be abandoned. The defender may move advisors or elephants away from the general, or even sacrifice them intentionally, to ward off attack by a cannon.

The two chariots are not normally lined up together in Chinese chess, as they are the most powerful piece and in doing so, a player risks the chances of losing at least one chariot to an inferior piece of the enemy. Depending on the situation, it may be advantageous to position a chariot at one of the corners of the enemy's side of the board, where it is very difficult to dislodge, and threatens the enemy general.

It is common to use the cannons independently to control particular ranks and files.

It is also common to pull an early checkmate on beginning players, using the double cannon technique. This checkmate plan is similar to the western chess's four-move checkmate, and can be executed also in four moves. However, this checkmate is easily countered by the horse reply.

Mǎ lái tiào:
Black moves his horse out from h10 to g8
(Noted as "馬(18)–37" or "H8+7")

Since (unlike in Western chess) the left and right flank of the starting setup are symmetrical and therefore equivalent, it is customary to always make the first move from the right flank. Starting on the left flank is considered to be needlessly confusing.

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. 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.) dāng tóu pào, mǎ lái tiào ([listen]). The notation for this is "1. 炮 (32)–35, 馬 (18)–37" or "1. C2.5 H8+7". See also the diagrams to the right.

This is usually followed by the most common second move, 出車 (trad.) / 出车 (simp.) chū jū — "chariot sortie" — in which the first player moves a chariot forward one space (usually the right one).

The most common reply is to move the right advisor diagonally. 上士 shàng shì. This is to prevent a series of events that leads to the first player quickly checkmating the second.

Less common first moves include:

moving an elephant to the central column
advancing the soldier on the third or seventh file
moving a chariot forward by one space
moving either cannon behind the 2nd pawn from the left or right

General advice for the opening includes rapid development of at least one chariot, because it is the most powerful piece and the only long-range piece besides the cannon. The opening is not as much a struggle for control of the center as openings are in Western chess. It may not be a bad move to develop one horse to the edge of the board, for example, to avoid being blocked by one of one's own pawns that cannot advance. Usually, at least one horse should be moved to the middle.

History

Chinese chess has a long history. Though its precise origins have not yet been definitely confirmed, our earliest indications reveal the game may have been played as early as the 4th century BC, by Meng Changjun for example. (See chess in early literature or timeline of chess.) Judging by its rules, we can conclude that the origin of Chinese chess was apparently closely related to military strategists in ancient China.

The word xiàngqí's meaning "figure game" can also be treated as meaning "constellation game". It is believed by Western culture that xiàngqí is derived from chess, originating in India and adapted in China to use the board of a pre-existing Chinese game that had the same name and different rules. Sometimes the xiàngqí board's "river" is called the "heavenly river", which may mean the Milky Way; that previous xiàngqí game may have been based on movements of sky objects.

During the Spring and Autumn Period and the Warring States Period, wars were fought for years running. A new chess game was patterned after the array of troops (according to a hypothesis by David H. Li, this was developed by Han Xin in the winter of 204 BC-203 BC to prepare for an upcoming battle). This was the earliest form of Chinese chess.

Because some remnants of Chinese silk have been dated in Egypt as early as 1070 BC (see Silk Road) and because of the astounding similarities between xiangqi and an ancient "game" board portrayed in the tomb of Egyptian Queen Nefertari (see origins of chess) the two ancient countries could possibly have influenced one another in the creation of both games. Nefertari's "game" may have provided early inventors with a fundamental model upon which xiangqi and other ancient chess variants are patterned. The ancient Chinese game of Liubo may also have had an influence as well. Assuming our present day historical records to be accurate, both Nefertari's "game" and Liubo are approximately a thousand years older than xiangqi.

During the Cao Wei, Jin and Northern and Southern Dynasties, a kind of chess game was popular among the people. It laid a foundation for the finalized pattern of Chinese chess. In ancient times, both highbrows and lowbrows enjoyed Chinese chess.

During the reign of Suzong of the Tang Dynasty, Prime Minister Niu Sengru wrote a fictional story about chess. That occurred during the Baoying period, so it was named Baoying chess. Baoying chess had six pieces. He wrote about the rules of the chess. Baoying chess produced a significant influence on the chess in subsequent years.

Three forms of chess took shape after the Song Dynasty. One of them consisted of 32 pieces. They were played on a chessboard with 9 vertical lines and 9 horizontal lines. Popular in those days was a chessboard without a river borderline; the Korean game of janggi is derived from this earlier riverless version. The river borderline was added later, and this form of the game has lasted to the present day.

With the economic and cultural development during the Qing Dynasty, Chinese chess entered a new stage. Many different schools of chess circles and chess players came into prominence. With the popularization of Chinese chess, many books and manuals on the techniques of playing chess were published. They played an important role in popularizing Chinese chess and improving the techniques of play in modern times.

Xiangqi tournaments and leagues

In Europe and Asia there are significantly more xiangqi leagues and clubs than in the United States. 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 in Malaysia.

In addition, there are also several international federations and tournaments. For example, the Chinese Xiangqi Association hosts several tournaments every year, including the Yin Li and Ram Cup TournamentsFrom [rec.games.chinese-chess FAQ #21] “What are some of the top tournaments in the world?”. There is also an Asian Xiangqi Federation[Asian Xiangqi Federation] homepage includes English translations of Asian tournament results, rules, etc. and a World Xiangqi Federation[World Xiangqi Federation homepage]., which hosts tournaments and competitions bi-annually, though most are limited to players from member nations.

Xiangqi has spread from Asia into the United States, where it has gained increasing popularity. However, there remains no official league or nationwide club for xiangqi in the U.S.From [rec.games.chinese-chess FAQ #20], and xiangqi is mainly played recreationally or at local clubs, usually located in Chinatowns.

Rankings

The Asian Xiangqi Federation and its corresponding member associations also rank players in a number format similar to the rankings of chess. The best player in China, according to the 2005 Chinese National Ratings, is Lu Qin with a rating of 2649[link].. In addition, the Asian Xiangqi Federation also bestows the title of grandmaster to select individuals around the world who have excelled at xiangqi or have made special contributions to the game. Though there are no specific criteria for becoming a grandmaster, the list of grandmasters is limited to fewer than a hundred people[rec.games.chinese-chess FAQ lists the International Grandmasters by country]..

Xiangqi and computers

As of 2005, the world's best human xiangqi players remain better than the world's best computer players.

The game-tree complexity of xiangqi is approximately 10¹⁵⁰, so it is projected that a human top player will be defeated before 2010Yen, Chen, Yang, Hsu, 2004, [Computer Chinese Chess]..
