Shogi (将棋 shōgi?) or Japanese chess (literally "generals' chess"; pronounced /ˈʃoʊɡiː/ in English) is the most popular of a family of chess variants native to Japan. A Strategy is a long term plan of action designed to achieve a particular goal, most often "winning A chess variant is a Game derived from related to or similar to Chess in at least one respect For a topic outline on this subject see List of basic Japan topics. Unique to the Japanese forms of chess are the drops, moves whereby captured enemy pieces are returned into play as ally pieces.

Rules of the game

Objective

Technically the game is won when a king is captured, though in practice defeat is conceded at mate or when mate becomes inevitable. Checkmate (frequently shortened to mate) is a situation in Chess (and in other Boardgames of the Chaturanga family in which one player's

Two players, Black and White (or sente 先手 and gote 後手), play on a board composed of rectangles in a grid of 9 ranks (rows) by 9 files (columns). The rectangles are undifferentiated by marking or colour.

Each player has a set of 20 wedge-shaped pieces of slightly different sizes. Except for the kings, opposing pieces are differentiated only by orientation, not by marking or color. From largest to smallest (most to least powerful), the pieces are:

The pieces of the two players do not differ in colour, but instead each faces forward, toward the opposing side. This shows who controls the piece during play.

The Japanese characters have deterred many people from learning shogi. This has led to "Westernized" or "international" pieces, which replace the characters with iconic symbols. The term Western world, the West or the Occident ( Latin: occidens -sunset -west as distinct from the Orient) can have multiple meanings However, partially because the traditional pieces are already iconic by size, with more powerful pieces being larger, most Western players soon learn to recognize them, and Westernized pieces have never become popular.

English speakers sometimes refer to promoted bishops as horses and promoted rooks as dragons, after their Japanese names, and generally use the Japanese term tokin for promoted pawns. Silver generals and gold generals are commonly referred to simply as silvers and golds.

The characters inscribed on the reverse sides of the pieces to indicate promoted rank may be in red ink, and are usually cursive. The characters on the backs of the pieces that promote to gold generals are cursive variants of 金 'gold', becoming more cursive (more abbreviated) as the value of the original piece decreases. These cursive forms have these equivalents in print: 全 for promoted silver, 今 for promoted knight, 仝 for promoted lance, and 个 for promoted pawn (tokin). Another typographic convention has abbreviated versions of the unpromoted ranks, with a reduced number of strokes: 圭 for a promoted knight (桂), 杏 for a promoted lance (香), and the 全 as above for a promoted silver, but と for tokin.

Player ranking

Players are ranked from 15 kyū to 1 kyū and then from 1 dan and upwards; this is the same terminology as in karate, go, calligraphy and many other arts in Japan. ( or is a martial art developed in the Ryukyu Islands from indigenous fighting methods and Chinese Kenpō. The art of Calligraphy is widely practiced and revered in the East Asian Civilizations that use or used Chinese characters. Professional players operate with their own scale, from professional 4 dan and upwards to 9 dan for elite players. Amateur and professional ranks are offset, corresponding as here.

Setup

The starting setup of a game of shogi.
The starting setup of a game of shogi.

Each player places his pieces in the positions shown below, facing the opponent.

That is, the first rank is |L|N|S|G|K|G|S|N|L|.

Traditionally, even the order of placing the pieces on the board is determined. There are two recognized orders, ohashi and ito. The Japanese-language page Shogi Pineapple indicates the two orders; ohashi is depicted on the left and ito on the right.

Gameplay

The players alternate taking turns, with Black (the side containing the Jeweled General) playing first. The terms "Black" and "White" are used to differentiate the two sides, but there is no actual difference in the color of the pieces. For each turn a player may either move a piece which is already on the board (and potentially promote it, capture an opposing piece, or both) or else "drop" a piece that has already been captured onto an empty square of the board. These options are detailed below.

Professional games are timed as in International Chess, but professionals are never expected to keep time in their games. Instead a timekeeper is assigned, typically an apprentice professional. Time limits are much longer than in International Chess (9 hours a side plus extra time in the prestigious Meijin title match), and in addition byōyomi (literally "second counting") is employed. is one of the seven titles in Japanese professional Shogi, and is the most prestigious title along with Ryu-oh. This means that when the ordinary time has run out, the player will from that point on have a certain amount of time to complete every move (a byōyomi period), typically upwards of one minute. The final ten seconds are counted down, and if the time expires the player to move loses the game immediately. Amateurs often play with electronic clocks that beep out the final ten seconds of a byōyomi period, with a prolonged beep for the last five.

Movement and capture

If an opposing piece occupies a legal destination for a friendly piece (that is, a piece belonging to the player whose turn it is to move), it may be captured by removing it from the board and replacing it with the friendly piece. It is not possible to move to or through a square occupied by another friendly piece, or to move through a square occupied by an opposing piece. It is common to keep captured pieces on a wooden stand (or komadai) which is traditionally placed so that its bottom left corner aligns with the bottom right corner of the board from the perspective of each player. It is not permissible to hide pieces from full view. This is because captured pieces, which are said to be in hand, have a crucial impact on the course of the game.

The knight jumps, that is, it passes over any intervening piece, whether friend or foe, without an effect on either. It is the only piece to do this.

The lance, bishop, and rook are ranging pieces: They can potentially move any number of squares along a straight line limited by the edge of the board. If an opposing piece intervenes, it may be captured by removing it from the board and replacing it with the moving piece. If a friendly piece intervenes, one is limited to a distance that stops short of that square; if the friendly piece is adjacent, one may not move in that direction at all.

All pieces but the knight move either orthogonally (that is, forward, backward, or to the side, in the direction of one of the arms of a plus sign, +), or diagonally (in the direction of one of the arms of a multiplication sign, ×).

King

A King can move one square in any direction, orthogonal or diagonal.

Because they cannot move orthogonally, the opposing unpromoted bishops can only reach half the squares of the board.

Gold general

A gold general can move one square orthogonally, or one square diagonally forward, giving it six possible destinations. It cannot move diagonally backward.

Because an unpromoted silver can retreat more easily than a promoted one (see below), it is very common to leave a silver unpromoted at the far side of the board.

Knight

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. It cannot move to the sides or backwards.

The knight is the only piece that ignores intervening pieces on the way to its destination. It is not blocked from moving if the square in front of it is occupied, but neither can it capture a piece on that square.

It is often useful to leave a knight unpromoted (see below) at the far side of the board. However, since a knight cannot move backward or to the sides, it must promote when it lands on one of the two far ranks and would otherwise be unable to move further.

Lance

A lance can move any number of free squares directly forward. It cannot move backward or to the sides.

Unlike the pawns of international chess, shogi pawns capture the same way they otherwise move, directly forward.

There are two restrictive rules for where a pawn may be dropped. (See below. )

Promotion

A player's promotion zone is the far third of the board, the three ranks occupied by the opposing pieces at setup. If a piece moves across the board and part of that path lies within the promotion zone, that is, if it moves into, out of, or wholly within the zone, but not if it is dropped (see below), then that player may choose to promote the piece at the end of the turn. Promotion is indicated by turning the piece over after it moves, revealing the character for the promoted rank.

When captured, pieces lose their promoted status. Otherwise promotion is permanent.

Promoting a piece has the effect of changing how that piece moves. Each piece promotes as follows:

Mandatory promotion

If a pawn or lance reaches the far rank or a knight reaches either of the two farthest ranks, it must promote, as it would otherwise have no legal move on subsequent turns. A silver general never needs to promote, and it is often advantageous to keep a silver general unpromoted.

Captured pieces are truly captured in shogi. They are retained "in hand", and can be brought back into play under the capturing player's control. On any turn, instead of moving a piece on the board, a player may take a piece that had been previously captured and place it, unpromoted side up, on any empty square, facing the opposing side. The piece is now part of the forces controlled by that player. This is termed dropping the piece, or just a drop.

A drop cannot capture a piece, nor does dropping within the promotion zone result in immediate promotion. However, either capture or promotion may occur normally on subsequent moves by the piece.

A pawn, knight, or lance may not be dropped on the far rank, since it would have no legal move on subsequent turns. Similarly, a knight may not be dropped on the penultimate rank.

There are two other restrictions when dropping pawns:

  1. A pawn cannot be dropped onto the same file (column) as another unpromoted pawn controlled by the same player. (A tokin does not count as a pawn. ) A player who has an unpromoted pawn on every file is therefore unable to drop a pawn anywhere. For this reason it is common to sacrifice a pawn in order to gain flexibility for drops.
  2. A pawn cannot be dropped to give an immediate checkmate. Checkmate (frequently shortened to mate) is a situation in Chess (and in other Boardgames of the Chaturanga family in which one player's However, other pieces may be dropped to give immediate checkmate, a pawn that is already on the board may be advanced to give checkmate, and a pawn may be dropped so that either it or another piece can give checkmate on a subsequent turn.

It is common for players to swap bishops, which face each other across the board. This leaves each player with a bishop "in hand" to be dropped later, and gives an advantage to the player with the stronger defensive position.

Check and mate

When a player makes a move such that the opposing king could be captured on the following turn, the move is said to give check to the king; the king is said to be in check. If a player's king is in check and no legal move by that player will get the king out of check, the checking move is also checkmate (tsumi 詰み) and effectively wins the game. Checkmate (frequently shortened to mate) is a situation in Chess (and in other Boardgames of the Chaturanga family in which one player's

To give the warning "check!" in Japanese, one says "ōte!" (王手). However, this is an influence of international chess and is not required, even as a courtesy.

A player is not allowed to give perpetual check. In the game of Chess, perpetual check is a situation in which one player can force a draw by an unending series of checks Such a situation typically arises

Winning the game

A player who captures the opponent's king wins the game. In practice this rarely happens, as a player will concede defeat when loss is inevitable.

In professional and serious amateur games, a player who makes an illegal move loses immediately.

There are two other possible, if uncommon, ways for a game to end: repetition (千日手 sennichite) and impasse (持将棋 jishōgi).

If the same game position occurs four (formerly three) times with the same player to play, the game is considered a draw. For two positions to be considered the same, the pieces in hand must be the same as well as the positions on the board. However, if this occurs with one player giving perpetual check, then that player loses.

The game reaches an impasse if both kings have advanced into their respective promotion zones and neither player can hope to mate the other or to gain any further material. If this happens, the winner is decided as follows: Each rook or bishop scores 5 points for the owning player, and all other pieces except kings score 1 point each. (Promotions are ignored for the purposes of scoring. ) A player scoring fewer than 24 points loses. (Naturally, if neither player has fewer than 24, the game is a draw. ) Jishōgi is considered an outcome in its own right rather than no contest, but there is no practical difference.

In professional tournaments the rules typically require drawn games to be replayed with colours (sides) reversed, possibly with reduced time limits. This is rare compared to chess and xiangqi, occurring at a rate of 1-2% even in amateur games. Chess is a recreational and competitive Game played between two players. The 1982 Meijin title match between Nakahara Makoto and Kato Hifumi was unusual in this regard, with jishōgi in the first game (only the fifth draw in the then 40-year history of the tournament), a game which lasted for an unusual 223 moves (not counting in pairs of moves), with an astounding 114 minutes spent pondering a single move, and sennichite in the sixth and eighth games. is one of the seven titles in Japanese professional Shogi, and is the most prestigious title along with Ryu-oh. Thus this best-of-seven match lasted ten games and took over three months to finish; Black did not lose a single game and the eventual victor was Katō at 4-3.

Handicaps

Games between players of disparate strengths are often played with handicaps. In a handicap game, one or more of White's pieces are removed from the setup, and in exchange White plays first. Note that the missing pieces are not available for drops and play no further part in the game. The imbalance created by this method of handicapping is not as strong as it is in international chess because material advantage is not as powerful in shogi.

Common handicaps, in increasing order of severity, include:

Other handicaps are also occasionally used. The relationship between handicaps and differences in rank is not universally agreed upon, with several systems in use.

Game notation

The method used in English-language texts to express shogi moves was established by George Hodges in 1976. Year 1976 ( MCMLXXVI) was a Leap year starting on Thursday (link will display full calendar of the Gregorian calendar. It is derived from the algebraic notation used for chess, but differs in several respects. Algebraic chess notation is used to record and describe the moves in a game of Chess. It is not used in Japanese-language texts, as it is no more concise than kanji.

A typical move might be notated P-8f. The first letter represents the piece moved: P for Pawn. (There is also L lance, N knight, S silver, G gold, B bishop, R rook, K king, as above. ) Promoted pieces are indicated by a + in front of the letter: +P is a tokin (promoted pawn).

Following the abbreviation for the piece is a symbol for the type of move: – for a simple move, x for a capture, or * for a drop. Next is the square on which the piece lands. This is indicated by a numeral for the file and a lowercase letter for the rank, with 1a being the top right corner (as seen by Black) and 9i being the bottom left corner. This is based on Japanese convention, which, however, uses Japanese numerals instead of letters. For example, square 2c is "2三" in Japanese.

If a move entitles the player to promote, then a + is added to the end if the promotion was taken, or an = if it was declined. For example, Nx7c= indicates a knight capturing on 7c without promoting.

In cases where the piece is ambiguous, the starting square is added to the letter for the piece. For example, at setup Black has two golds which can move to square 5h (in front of the king). These are distinguished as G6i-5h (from the left) and G4i-5h (from the right).

Moves are commonly numbered as in chess. For example, the start of a game might look like this:

    1.  P-7f   P-3d
    2.  P-2f   G-3b
    3.  P-2e   Bx8h+
    4.  Sx8h   S-2b

In handicap games White plays first, so Black's move 1 is replaced by an ellipsis. Ellipsis (plural ellipses; from Greek 'omission' in Printing and Writing refers to a mark or series of marks that usually indicate an intentional

Strategy and tactics

Shogi is similar to chess but has a much larger game tree complexity because of the use of drops. Combinatorial game theory has several ways of measuring game complexity. [1] However, like chess, the game can be divided into the opening, middle game and endgame, each requiring a different strategy.

The opening of shogi is generally slower than that of chess, due to the larger board and less mobile pieces. But since a quick offense will leave a player's home territory open to drop attacks as soon as pieces are exchanged, the aim of the opening is to build a castle with three generals. [2] There are two types of openings typically used in Shogi: static rook and ranging rook.

Players can both move the rook pawn forward, or more commonly, advance the pawn above and to the right of the bishop. The former is known as a rook opening while the latter is a bishop opening. When doing a bishop opening, it's common to exchange pieces by having one bishop attack the other. This allows each player to return their newly captured bishop into play anywhere on the board. However, it is not always advantageous to exchange bishops, depending on what they intend to do next.

Professional shogi players tend to evaluate the 'flow' of the game, that is, the sequence of moves leading to the current position and its likely development, much more than chess players. [3]

Because pawns attack head on, and cannot defend each other, they tend to be lost early in the game, providing ammunition for such attacks. Dropping a pawn behind enemy lines, promoting it to a "tokin" (gold general), and dropping a second pawn immediately behind the "tokin" so that they protect each other makes a strong attack; it threatens the opponent's entire defense, but provides little value to the opponent if the attack fails and the pieces are captured.

Players raised on International Chess often make poor use of drops,[4] but dropping is half the game. If a player has more than a couple of captured pieces in hand, it is likely that dropping attacks are being overlooked. However, it is wise to keep a pawn in hand, and often to exchange pieces if necessary to get one. Compared to International Chess, Shogi players are more likely to sacrifice pieces (even valuable ones), if the resulting capture can be dropped back into play for a specific purpose.

Attacking pieces can easily become trapped behind enemy lines, as the opponent can often drop a pawn on a protected square to cut off the line of retreat. For this reason, rooks, which can retreat in only one direction, are commonly kept at a safe distance in the early parts of the game, and used to support attacks by weaker pieces. However, once the game has opened up, a promoted rook is an especially deadly piece behind enemy lines. Kings can also be easily trapped by their own pieces, so a good last-ditch defensive effort is to open a back door through the pawn line to allow kings to escape. Kings are more difficult to checkmate in the open, especially if the opponent does not have many ranged pieces in play.

Many common opening attacks involve advancing a silver, and ideally a pawn, along a file protected by the rook. This is the climbing silver attack. [4] Because silvers have more possibilities for retreat, while golds better defend their sides, silvers are generally considered superior as attacking pieces, and golds superior as defensive pieces. It is common practice to defend the king with three generals, two golds and a silver.

There are various furibisha or "ranging rook" openings where the rook moves to the center or left of the board to support an attack there, typically with the idea of allowing the opponent to attack while arranging a better defence and aiming for a counterattack. However, as the most powerful piece on the board, the rook invites attack, and in most cases, especially for weaker players, it is a good idea to keep the king well away from the rook. Leaving a king on its original square (igyoku or a "sitting king")[4] is a particularly dangerous position. [4]

Advancing a lance pawn can open up the side of the board for attack. Therefore, when a player first advances a lance pawn, it is usual for the opponent to answer by advancing the opposing pawn, in order to avoid complications later in the game. It also allows the king to escape if attacked from the side.

Because defense is so important, and because shogi pieces are relatively slow movers, the opening game tends to be much longer in shogi than in International Chess,[4] commonly with a dozen or more moves to shore up defenses before the initial attack is made. There are several strong defensive fortifications known as castles.

The Yagura castle

The Yagura castle or defensive opening
The Yagura castle or defensive opening

The Yagura castle is considered by many to be the strongest defensive position in shogi. [4] It has a strongly protected king; a well fortified line of pawns; and the bishop, rook, and a pawn all support a later attack by the rook's silver or knight. It is notoriously difficult to break down with a frontal assault, though it is weaker from the side. It is typically used against ibisha or "static rook" openings, which involve advancing the rook's pawn. However, one's opponent may just as easily adopt this defense, giving neither side an advantage.

There is a good deal of flexibility in the order of moves when building the Yagura defense, and the possibilities will not be listed here. The only point to keep in mind is that the generals should move diagonally, not directly forward. [4] However, there is a strong intermediate position called the kani ("crab"). [4] It has the three pawns on the left side advanced to their final Yagura positions, and on the second rank all four generals are lined up next to the bishop, which is still in its starting position: |B|G|S|G|S| bishop-gold-silver-gold-silver. The king is moved one square to the left, behind the middle silver.

While forming the castle, the rook's pawn is often advanced two squares in preparation for a climbing rook assault on the opposing king. Another common preparation is to advance the adjacent silver's pawn square, allowing passage for both the rook's silver and knight. These offensive moves are not properly part of the castle, but the two-square pawn advance must be carried out early if there is to be room for it, and so it is often done while still castling. [4]

A common attack against the Yagura defense is to advance the rook's knight directly forward, defended by the rook and with a pawn in hand, to attack the fortifications on either side of the castled king. [4] If the defender has answered a lance's pawn advance on that side, a pawn may be dropped where the edge pawn had been. If the defending silver has moved or is not yet in position, a pawn may be dropped there.

The Mino-Gakoi castle

The Mino-Gakoi castle or defensive opening

A defensive position that is considered easier for beginners, but still popular with professionals, is the Mino-Gakoi castle. The King is placed in a safe position, while the three generals work well to back each other up. This is sometimes used when a player chooses a bishop opening rather than the rook-pawn opening.

The Mino-Gakoi takes six moves to complete, not necessarily in this order:

  1. Move the rook to the left side of the board, preferably to the fourth column. This move must be first.
  2. Move the king to where the rook started, 3 moves.
  3. Move the silver general next to the king up one space.
  4. Move the left-side gold general diagonally up and right so that it is protected by the other gold general, which hasn't moved yet.

Additional moves to take:

  1. Move the edge pawn one, or even better two squares forward. This gives king an escape route at the end game.

The Anaguma Castle

The Anaguma, or "Bear" castle
The Anaguma, or "Bear" castle

A third defense often used in professional Shogi is the Anaguma or "Bear" Castle. The castle can be executed in either side of the board depending on strategic needs, but typically will happen on the rook side. The end-result will place the king in the far corner where the lancer started, and is defended by two gold generals and one silver.

One suggested strategy for a rook-side castle is:

History

Ancient shogi

Arrival in Japan

Shogi is said to be derived from the game of chaturanga played in ancient India, which spread throughout the continent of Eurasia, developing into a variety of related games. This article is about two-handed ancient game Chaturanga For the four-handed version played with dice see Chaturaji. India, officially the Republic of India (भारत गणराज्य inc-Latn Bhārat Gaṇarājya; see also other Indian languages) is a country In the West, it became chess, in China xiangqi (象棋), on the Korean Peninsula janggi (장기), and in Thailand makruk. Chess is a recreational and competitive Game played between two players. China ( Wade-Giles ( Mandarin) Chung¹kuo² is a cultural region, an ancient Civilization, and depending on perspective a National Physical geography See also Geography of North Korea, Geography of South Korea Mountains cover 70 percent of the Korean Peninsula and arable plains are Janggi is the Korean name for a strategic Board game widespread in Korea The Kingdom of Thailand (ˈtaɪlænd ราชอาณาจักรไทย, râːtɕʰa-ʔaːnaːtɕɑ̀k-tʰɑj Makruk ( Thai: หมากรุก (or Thai chess) is a Board game descended from the 6th century Indian game of Chaturanga

It is not clear when shogi was brought to Japan. This is in contrast to the game of go, which was almost certainly brought to Japan in or around the Nara period, since a go board is stored in the treasury of Shōsōin (正倉院?).

Background Yuwen Yong was born in 543 as the fourth son of the Western Wei paramount general Yuwen Tai. The Northern Zhou Dynasty (Chinese北周 followed the Western Wei, and ruled northern China from 557 to 581. Kibi no Makibi (吉備真備 695–775 was a Japanese scholar and noble during the Nara period.

The Tang Dynasty ( Middle Chinese: dhɑng (June 18 618&ndashJune 4 907 was an imperial dynasty of China preceded by the Sui Dynasty and followed by

There are several theories about when shogi spread to Japan, but the earliest plausible date is around the 6th century. The 6th century is the period from 501 to 600 in accordance with the Julian calendar in the Christian / Common Era. It is thought that the pieces used in the shogi of the time were not the current five-sided pieces, but three-dimensional figures, as were used in Chaturanga. This parallels the changes in chess pieces, which are more representational and less abstract than those made earlier. However, a large problem with this theory is that as pieces in this form have never been found, let alone stored in the treasury of Shōsōin, there is little physical evidence supporting it.

Another theory gives a later date, stating that shogi was brought to Japan after the start of the Heian period. The is the last division of classical Japanese history, running from 794 to 1185. According to this theory, games such as xiangqi from China and janggi from Korea came to Japan at this time, but as these games are different from shogi, for example in that pieces are placed on the intersections of lines, serious doubts about this theory remain. The games of makruk from Thailand and Cambodia and sittuyin from Myanmar have an elephant which moves in the same way as the silver general, but it is difficult to imagine how the game could have been spread by sea to Japan given the shipbuilding technology of the time, and there are therefore no clear answers.

Shogi in the Heian period

One of the oldest documents indicating the existence of shogi is Kirinshō (麒麟抄?), written by Fujiwara Yukinari (藤原行成?) (972 - 1027), a seven-volume work which contains a description of how to write the characters used for shogi pieces, but the most generally accepted opinion is that this section was added by a writer from a later generation. Shin Saru Gakuki (新猿楽記?) (1058 - 1064), written by Fujiwara Akihira also has passages relating to shogi, and is regarded as the earliest document on the subject.

The oldest archaeological evidence is a group of 16 shogi pieces excavated from the grounds of Kōfuku-ji in Nara Prefecture, and as a wooden writing plaque written on in the sixth year of Tenki (1058) was found at the same time, the pieces are thought to be of the same period. is a Buddhist Temple in the city of Nara, in Nara prefecture, Japan. WikipediaWikiProject Japanese prefectures for guidelines --> is a prefecture in the Kinki region on Honshū Island, Japan The pieces of the time appear to have been simple ones made by cutting a writing plaque and writing directly on the surface, but they have the same five-sided shape as modern pieces. As "Shin Saru Gakuki", mentioned above, is of the same period, this find is backed up by documentary evidence.

The dictionary of common folk culture, Nichūreki (二中歴?), which it is estimated was created between 1210 and 1221, a collection based on the two works Shōchūreki (掌中歴?) and Kaichūreki (懐中歴?), thought to have been written by Miyoshi Tameyasu (三善為康?), describes two forms of shogi, large (dai) shogi and small (shō) shogi. So as not to confuse these with later types of shogi, in modern times these are called Heian shogi (or Heian small shogi) and Heian dai shogi. Heian shōgi (平安将棋 " Heian era chess" is a predecessor of modern Shogi (Japanese chess Heian dai shogi (平安大将棋 'Heian (Era large chess' is an early large board variant of Shogi (Japanese chess as it was played in the Heian period Heian shogi is the version on which modern shogi is based, but it is written that one wins if one's opponent is reduced to a single king, apparently indicating that at the time there was no concept of pieces in the hand.

The pieces used in these variants of shogi consist of those used in Heian shogi: the king, gold general, silver general, knight, lance, and pawn, and those used only in Heian great shogi: the copper general, iron general, side mover, tiger, flying dragon, free chariot and go between. According to Kōji Shimizu, chief researcher at the Archaeological Institute of Kashihara, Nara Prefecture, the names of the Heian shogi pieces keep those of chaturanga (general, elephant, horse, chariot and soldier), and add to them the five treasures of Buddhism (jewel, gold, silver, katsura tree, and incense). Cercidiphyllum is a genus containing two species of Plants both commonly called Katsura There is also a theory by Yoshinori Kimura that while chaturanga was from the start a game simulating war, and thus pieces were discarded once captured, Heian shogi involved pieces kept in the hand. better known through his persona is a Japanese professional wrestler, who currently works for New Japan Pro Wrestling among other places

The development of shogi

In games around the world related to shogi, there have been changes in the rules with the passage of time, such as increasing the abilities of the pieces or their numbers, as winning strategies have been discovered, and the Japanese game of shogi is no exception to this.

Around the 13th century, the game of dai shogi, created by increasing the number of pieces in Heian shogi, was played, and the game of sho shogi, which adds the rook, bishop and drunken elephant from dai shogi to Heian shogi. Around the 15th century, as the rules of dai shogi had become too complicated, they were simplified, creating the game of chu shogi, which is close to the modern game. It is thought that the rules of modern shogi were fixed in the 16th century, when the drunken elephant was removed from the set of pieces. According to Shoshōgi Zushiki (諸象戯図式?), a set of shogi rules published in 1696, during the Ganroku period, it states that the drunken elephant piece was removed from the game of sho shogi by Emperor Go-Nara during the Tenmon period (1532 - 1555), but whether or not this is true is not clear. Emperor Go-Nara (後奈良天皇 Go-Nara-tennō) ( January 26, 1497 - September 27, 1557) was the 105th emperor is the Ninja art of understanding and using Meteorology as a strategic weapon

As many as 174 shogi pieces have been excavated from the Ichijōdani Asakura Family Historic Ruins, which are thought to be from the latter half of the 16th century. are historic ruins located in the Kidonouchi section of Fukui, Fukui Prefecture, Japan. Most of these pieces are pawns, but there is also one drunken elephant, leading to the hypothesis that in this period variations of shogi with and without the drunken elephant existed side by side.

One point of note in the history of this family of games is that it was during this period that the unique rule in Japanese shogi was developed whereby captured pieces (pieces in the hand) could be returned to the board. It is thought that the rule of pieces in the hand was proposed around the 16th century, but there is also a theory that this rule existed from the time of Heian sho shogi.

In the Edo period, more types of shogi with yet more pieces were proposed: tenjiku shogi, dai dai shogi, maka dai dai shogi, tai shogi (also called "dai shogi", but termed "tai shogi" to avoid confusing the two) and taikyoku shogi. The, also referred to as the Tokugawa period (徳川時代 Tokugawa-jidai) is a division of Japanese history running from 1603 to 1868 Tenjiku shogi (天竺将棋 tenjiku shōgi or 天竺大将棋 tenjiku dai shōgi "exotic chess" is a large-board variant of Shogi Daidai shōgi (大大将棋 'huge chess' is a large board variant of Shogi (Japanese chess Warning This article is based on Western descriptions which contain many errors Tai shogi (泰将棋 tai shōgi or 無上泰将棋 mujō tai shōgi "grand chess" renamed from 無上大将棋 mujō dai shōgi "supreme Taikyoku shōgi (大局将棋 'ultimate chess' is a large board variant of shogi ( Japanese Chess) However, it is thought that these forms of shogi were only played to a very limited extent.

Modern shogi

Castle shogi and the iemotos

Modern shogi (hon shogi), like go, was officially approved by the Tokugawa shogunate. The Tokugawa shogunate, also known as the, and the, was a feudal regime of Japan established by Tokugawa Ieyasu and ruled by the Shoguns of In 1612, the shogunate passed a law giving endowments to shogi players including Kanō Sansa (加納算砂?) (Hon'inbō Sansa (本因坊算砂?)) and Shūkei (宗桂?) (who was given the name Ōhashi Shūkei (大橋宗桂?) after his death). Honinbō Sansa (本因坊算砂 1559&ndash June 13, 1623) was the assumed name of Kanō Yosaburo (加納 與三郎 one of the strongest Japanese Honinbō Sansa (本因坊算砂 1559&ndash June 13, 1623) was the assumed name of Kanō Yosaburo (加納 與三郎 one of the strongest Japanese These iemotos (families upholding the tradition of go or shogi) gave themselves the title of go-dokoro (碁所?) (literally, places of go) and shogi-dokoro (将棋所?), places of shogi. Iemoto (家元 lit "family foundation" is a Japanese term used to refer to the founder or current head master of a certain school of traditional Japanese art The first O-hashi Shu-kei received fifty koku of rice and five men. In the Kan'ei period (around 1630), the "castle shogi" (御城将棋?) tournament, where games were played before a shogun, was held. was a after Genna and before Shōhō. This period spanned the years from 1624 through 1643. During the time of the eighth shogun, Tokugawa Yoshimune, a system was established where the castle shogi tournament was held once a year on the 17th day on Kannazuki, and today the corresponding day in the modern calendar, November 17, has been designated Shogi Day. was the eighth Shogun of the Tokugawa shogunate of Japan, ruling from 1716 until his abdication in 1745 is a traditional name for the tenth month in the traditional Japanese Lunar calendar.

The Meijin (名人?), who were the iemotos of shogi, were paid endowments. Meijin (名人 literally translated means "Brilliant Man" It is the name of the second most prestigious Japanese Go Tournament. Meijin (名人 literally translated means "Brilliant Man" It is the name of the second most prestigious Japanese Go Tournament. Iemoto (家元 lit "family foundation" is a Japanese term used to refer to the founder or current head master of a certain school of traditional Japanese art Over the reign of the shogunate, the title of meijin became a hereditary title of the Ōhashi family and one of its branches, and the Itō family. Today the title of meijin is still used, for the winner of the Meijin-sen competition. is one of the seven titles in Japanese professional Shogi, and is the most prestigious title along with Ryu-oh. It became a tradition for shogi players inheriting the title of meijin to present a collection of shogi puzzles to the shogunate government.

A number of genius shogi players emerged who were not hereditary meijin. Itō Kanju (伊藤看寿?) was born in the mid-Edo period, and showed promise as a potential meijin, but died young and never inherited the title (which was bestowed on him posthumously). Kanju was a skilled composer of shogi puzzles, and even today his collection of puzzles "Shogi Zukō" (将棋図巧?) is well known as one of the greatest works of its kind. In the late Edo period, Amano Sōho (天野宗歩?) came to prominence. As he was one of the "Arino group" of amateur shogi players, the rank of meijin was out of his reach, but he was feared for his skill, being said to have "the ability of a 13-dan player", and was later termed a kisei (棋聖?) (literally, wise man or master of shogi). The Kisei (棋聖 is a Go competition. The title meaning go sage in Japanese was a traditional honorary appellation given to a handful of players The Kisei (棋聖 is a Go competition. The title meaning go sage in Japanese was a traditional honorary appellation given to a handful of players More than a few count Sōho as one of the greatest shogi players in history.

Newspaper shogi and the formation of shogi associations

After the fall of the Tokugawa shogunate, the three shogi families were no longer paid endowments, and the iemoto system in shogi lost its power. The lines of the three families ended, and the rank of meijin came to be bestowed by recommendation. The popularity of amateur shogi continued in the Meiji period, with shogi tournaments and events held all over Japan, and "front-porch shogi" (縁台将棋?), played wherever people gathered, in bath houses or barber's shops. However, it is thought that, with the exception of a handful of high-ranking players at the end of the 19th century, it was impossible to make a living as a professional shogi player during this period.

From around 1899, newspapers began to publish records of shogi matches, and high-ranking players formed alliances with the aim of having their games published. Year 1899 ( MDCCCXCIX) was a Common year starting on Sunday (link will display the full calendar of the Gregorian calendar (or a Common A newspaper is a written Publication containing News, information and Advertising, usually printed on low-cost paper called Newsprint. In 1909, the Shogi Association (将棋同盟社?) was formed, and in 1924, the Tokyo Shogi Association (東京将棋同盟社?) was formed, with Sekine Kinjirō (関根金次郎?), a thirteenth-generation meijin, at its head.

The first Meijin title match (名人戦 meijin-sen?)

The ages of Ōyama and Habu

It was considered to be nearly impossible to hold all the titles at once, but in 1957, Kōzō Masuda took all three of the titles which existed at the time (Meijin, Kudan and Ōshō), to become a triple champion (三冠王?).

The year 1959 ( MCMLIX) was a Common year starting on Thursday (link will display full calendar of the Gregorian calendar. Ōyama went on to defend these titles for six years, a golden age which became known as the "Ōyama age". Ōyama reached a total of 80 title holding periods, an unprecedented achievement at the time, when there were fewer titles than at present.

After the number of titles increased to seven in 1983, it was believed to be impossible to hold all of them at once, but in 1996, Yoshiharu Habu became the first septuple champion (七冠王?), beginning an age known as the "Habu age".

His teacher is Tatsuya Futakami Since then, there has never been a time when he was without a title, and he has amassed a total of over 60 title holding periods.

The birth of the women's game

While there are both men and women among the ranks of professional shogi players, no woman player has yet won through the pro qualifier leagues (新進棋士奨励会 shinshin kishi shōreikai?) to become an officially certified professional player (棋士 kishi?). This served to slow the spread of the game among women, and to overcome the problem, the system of professional woman shogi players (女流棋士 joryū kishi?) was introduced.

In 1966, Akiko Takojima (蛸島彰子?) left the pro qualifier leagues at the 1-dan level and became the first professional woman shogi player. Year 1966 ( MCMLXVI) was a Common year starting on Saturday (link will display full calendar of the 1966 Gregorian calendar. However, at the time women's contests were not held, and so her only work as a professional was giving shogi lessons. In 1974, the first women's contest, the Women's Meijin title match (女流名人位戦 joryū meijin-sen?), was held, which Takojima won, becoming the first woman meijin. 1974 is often considered to be the year in which women's shogi began, and indeed the Ladies Shogi Professional (女流棋士会 joryū kishi kai?) organisation celebrates "anniversary parties" counting from this year.

At present there are more than 50 professional women players, and as well as the Women's Meijin title match, there is also the Women's Ōshō title match (女流王将戦?), the Women's Ōi title match (女流王位戦?), the Ōyama Meijin Cup Kurashiki-Tōka title match (大山名人杯倉敷藤花戦?), the Ladies' Open Tournament (レディースオープントーナメント?) and the Kajima Cup Women's Shogi Tournament (鹿島杯女流将棋トーナメント?), a total of six competitions. In addition, each of the standard professional tournaments has a women's section, in which the top women in each tournament compete.

Trends in the world of amateur shogi

Shogi is also well-known among the general public (amateurs). Two different rating systems based dan and kyu ranks are used, one for amateurs and one for professionals, with the highest ranks at amateur level, 4-dan or 5-dan, being equivalent to 6-kyu at the professional level. is a Japanese term used in Martial arts, chadō, Ikebana, go, Shogi and in other similar In the past, there were games between amateurs and professionals, but these were generally special match-ups organised by newspapers or magazines, or instructional games at events or shogi courses.

However, sometimes there are amateurs with an ability to rival professionals, some of whom earn a living as shinken-shi (真剣師?), gamblers playing for stakes. Motoji Hanamura (花村元司?) made enough to live on as a shinken-shi, before taking the entrance exam and turning professional in 1944. He later challenged Yasuharu Ōyama in the meijin-sen, but did not manage to take the title of meijin from him. Jūmei Koike (小池重明?) was another shinken-shi, who beat one professional after another in special matches, and won the title of amateur meijin twice in a row, putting him ahead of the crowd in the amateur world. Later, due in part to the instigation of Ōyama, the then chairman of the general assembly of the Japanese Shogi Association (棋士総会?), a vote was held on whether to accept Koike among their ranks, but there were concerns about his behaviour, and the vote went against him. Although he never became a professional, after his death, television programmes and books telling his story were produced, and he now has more fans all over Japan than when he was alive.

In recent times, the gap in ability between strong amateurs and professionals continues to diminish, and there are even official professional tournaments in which those with the best results in amateur shogi contests (将棋のアマチュア棋戦?) can take part. Some amateurs, including Tsuneyoshi Kobayashi (小林庸俊?), Takashi Amano (天野高志?), Hirukawa (蛭川敦?), Kiriyama (桐山隆?), Masaki Endō (遠藤正樹?), Masakazu Hayasaki (早咲誠和?) and Atsumoto Yamada (山田敦幹?) have been called "pro killers", and recently two young players, Yukio Katō (加藤幸男?) and Tōru Shimizukami (清水上徹?) have been making waves in the amateur world.

The number of players who have left the pro qualifier leagues and gone on to have success as amateurs has increased. Shōji Segawa (瀬川晶司?) retired from the qualifier leagues due to age restrictions, but went on to compete as an amateur in professional matches. His performance in the Ginga title match (銀河戦? ginga-sen) was particularly notable, and at one point he won over 70% of his matches with professionals. Sekawa submitted a petition requesting entry to the professional ranks to the Japan Shogi Association, and was granted exceptional permission to take the entrance exam. He is the first person to become a professional after retiring from the pro qualifier leagues.

In 2006, the Shogi Association officially admitted the entrance of amateurs and women professionals to the ranks of professionals (正棋士?), and announced details of an entrance exam for the 4-dan level (entering the "free class" (フリークラス?) level of the professional ranking league (順位戦?)) and the third-level pro qualifier league (奨励会三段リーグ?). Year 2006 ( MMVI) was a Common year starting on Sunday of the Gregorian calendar. Unless exceptional permission is granted, applicant normally need to have experience in the pro qualifier leagues, and cannot become professionals if they have retired from the leagues, but given the reforms taking place in the Association, it would be by no means unlikely if another Shōji Segawa were to appear.

The spread of shogi outside Japan

The game of shogi has developed independently inside Japan, and its pieces are differentiated by Japanese characters written on them, factors which have impeded the spread of the game outside Japan. By way of comparison, the game of go has spread internationally for a combination of many reasons, including the facts that it originated in China, its rules are (more or less) unified at an international level, it is played using black and white stones, and that it does not resemble games unique to another country (as is the case with shogi, which is one of many games resembling chess).

However, in the 1990s, efforts to make shogi popular outside Japan began in earnest. It has grown to be particularly popular in the People's Republic of China, and especially Shanghai. Talk People's Republic of China) PEOPLE'S REPUBLIC OF CHINA ARTICLE GUIDELINES Shanghai ( 上[[wikt 海|海]] is the largest city in China in terms of population and one of the largest urban areas in the world with over 20 million The January 2006 edition of Kindai Shogi (近代将棋?) states that Shanghai has a shogi population of 120,000 people. The game has been relatively slow to spread to countries where Chinese characters are not in common use, although attempts have been made to aid adoption by replacing the names of pieces with symbols indicating how they move.

Changes in the shogi population

According to the "Leisure White Paper" (レジャー白書?) by the Japanese Productivity Center for Socio-Economic Development (財団法人社会経済生産性本部?), the "shogi population" (the number of people of 15 years or over who play at least one game of shogi a year) fell from 16. 8 million in 1985 to 9 million in 2004, and 8. 4 million in 2006, and is continuing to fall gradually.

During the above period, in which the shogi population fell by a half, shogi has often appeared in the general media, for example Yoshiharu Habu's achievement of taking all seven titles in one year (1996), the airing of the NHK TV novel Futarikko (ふたりっ子?) (1996), the reporting of the affair between Makoto Nakahara (中原誠?) and Naoko Hayashiba (林葉直子?), Shōji Segawa taking the professional entrance exam (2005), and the debate about the management of the meijin-sen being passed to a different body (2006). is a professional shogi player.

However, none of these led to the birth of a "shogi boom", and in some cases unfavourable media reports accelerated the decline in the number of shogi fans.

The number of 10 to 19 year olds playing go is said in the "Leisure White Paper" above to have increased due to the story "Hikaru no Go", serialised in Shonen Jump. is a popular Japanese Manga and Anime Coming of age story based on the Board game Go written by Yumi Hotta and illustrated sometimes known as Weekly Jump and better known as Shōnen Jump, is one of the longest-running weekly Manga compilations in Japan (The overall go population is decreasing. ) However, the 2006 Leisure White Paper reports that go is most popular among those in their 60's, while shogi is most popular between those aged 10 to 19.

From around 1996, internet shogi programs such as Java Shogi (Java将棋?) and The Great Shogi (ザ・グレート将棋?), which allow users to play games over the internet without the need for an actual shogi set, grew to be widely used. At present, many games are played using services such as Shogi Club 24 (将棋倶楽部24?), Kindai Shogi Dojo (近代将棋道場?) and Yahoo! Japan Games. ( is the Japan affiliate of American Internet company Yahoo!.

Computer shogi

Developments have been made in computer shogi, a field of artificial intelligence concerned with the creation of computer programs which can play shogi. The research and development of shogi software has been carried out mainly by freelance programmers, university research groups and private companies. As the game of shogi has the distinctive feature of allowing captured pieces to be reused, shogi playing programs require a far higher degree of sophistication than programs playing similar games such as chess.

In the 1980s, due to the immaturity of the technology in such fields as programming, CPUs and memory, computer shogi programs took a long time to think, and often made moves for which there was no apparent justification. In Psychology, memory is an organism's ability to store retain and subsequently retrieve information These programs had the level of an amateur of kyu rank.

In the first decade of the new millennium, there have been large steps forward in both software and hardware technology, and it is currently estimated that the strongest program is prefecture champion class (around amateur 5-dan). In particular, computers are most suited to brute-force calculation, and far outperform humans at the task of finding ways of checkmating from a given position, which involves many fewer possibilities. In games with time limits of 10 seconds from the first move, computers are becoming a tough challenge for even professional shogi players. With Deep Blue having beaten a human chess champion, it is thought that humans will soon be unable to beat computers at shogi. Deep Blue is a Chess - playing Computer developed by IBM. On 11 May 1997, the machine won a six-game match by two wins to

In 2005, the Japan Shogi Association sent a message to professional shogi players, telling them that they should not compete against a computer in public without permission. The intentions behind this are to preserve the dignity of its professionals, and to make the most of computer shogi as a potential business opportunity.

The Japan Shogi Association did, however, give reigning Ryuo Watanabe permission to compete in a showdown against the strongest available Shogi program "Bonanza" (designed by Hoki Kunihito) on 21 March, 2007. The game was played with 2 hours each and 1 minute byo-yomi per move after that. Those conditions were thought to favor Watanabe. It was a very interesting match as Bonanza had corrected all its flaws Watanabe had discovered when preparing himself for the game using older game records. Watanabe commented after the game that he should have lost if Bonanza had played a defensive move before entering the endgame. This time, however, the computer choose to attack immediately instead of taking its time (and using its impressive endgame strategies) which cost it the match. Bonanza resigned after move 112. This game can be looked at as a clear example that computer Shogi, although still not perfect, has reached top pro level.
