Opposing Rook
In shogi, Opposing Rook (向かい飛車 ''mukaibisha,'' also Opposite Rook, Second File Rook) is a class of Ranging Rook openings in which the player's rook swings over to the second file if played by White or the eighth file if played by Black. The ''opposing'' name is used since if the Opposing Rook player's opponent is playing Static Rook, then the Opposing Rook player's rook will be on the same file as the opponent and the rooks will be facing or opposing each other. In order to play Opposing Rook, the player's bishop must be moved from its starting position (88 or 22 squares). This is usually done by either moving the bishop to the seventh file for Black or the third file for White or by exchanging bishops. If the opponent initiates the bishop exchange, the Opposing Rook player will capture the opponent's bishop with their rook. Traditional Opposing Rook White's Opposing Rook The opening starts by the usual four-move sequence that characterizes Static Rook vs Rang ...

Shogi
, also known as Japanese chess, is a strategy board game for two players. It is one of the most popular board games in Japan and is in the same family of games as Western chess, ''chaturanga, Xiangqi'', Indian chess, and '' janggi''. ''Shōgi'' means general's (''shō'' ) board game (''gi'' ). Western chess is sometimes called (''Seiyō Shōgi'' ) in Japan. Shogi was the earliest chess-related historical game to allow captured pieces to be returned to the board by the capturing player. This drop rule is speculated to have been invented in the 15th century and possibly connected to the practice of 15th century mercenaries switching loyalties when captured instead of being killed. The earliest predecessor of the game, chaturanga, originated in India in the sixth century, and the game was likely transmitted to Japan via China or Korea sometime after the Nara period."Shogi". ''Encyclopædia Britannica''. 2002. Shogi in its present form was played as early as the 16th century, while ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ranging Rook
Ranging Rook or Swinging Rook (振り飛車 ''furibisha'') openings in shogi position the rook to the center or left of the player's board to support an attack there. Ranging Rook strategies used in Ranging Rook vs Static Rook are among the oldest of shogi strategies attested in the historical documents that first describe the rules of shogi around 1600. Description Types of Ranging Rook Traditionally, Ranging Rook has been used as a defensive strategy for White against Static Rook openings played by Black. White's rook can be moved flexibly to counteract Black's attacks. These types of White openings are named simply Ranging Rook (振り飛車 ''furibisha''). In describing the game positions of both opponents, the term is Static Rook vs Ranging Rook (居飛車対振り飛車 ''ibisha tai furibisha''). In these games, Black has the initiative, and White quickly builds a defense by castling the king and seeks counterattacking opportunities. By default, the ...

Shogi Opening
A shogi opening ( ) is the sequence of initial moves of a shogi game before the middle game. The more general Japanese term for the beginning of the game is ()''.'' A '' jōseki'' () is the especially recommended sequence of moves for a given opening that was considered balanced play at one point in time for both sides by professional players. (However, some ''s'' have become outdated when they are reevaluated to no longer give balanced play.) ''s'' also typically include commentary about the possible reasons to deviate from the especially regarding blunders. Note that not all openings have ''s''. For example, trap openings like Demon Slayer, while they may have standard moves, are considered to favor one player and are not balanced play. Thus, the Demon Slayer opening is not a jōseki. Introduction The very first opening moves in most games are pawn pushes. In particular, most games start with two types of pawn pushes. A player can move the rook pawn forward (P-26) ...

Static Rook
Static Rook (居飛車 ''ibisha'') openings in shogi typically have the player's rook at its start position, which is the second file (on the 28 square) for Black and the eighth file (on the 82 square) for White. Explanation Static Rook is a set of openings in which the rook remains on its starting square, which is the 28 square if played by Black and the 82 square if played by White. It is also possible to include other openings where the rook moves to another file that is still on the players right side of the board, such as the third file or the fourth file. The reason for including these other openings where the rook is not technically ''static'' is because the typical castle fortifications constructed to the protect the Static Rook player's king are usually the same for these openings. Nonetheless, some shogi theory does categorize these openings with right side rook movement into the same group as Ranging Rook openings despite the disparity in castle formation. A ...

Fortress Opening
Fortress (矢倉 or 櫓 ''yagura'') is both a Static Rook opening (矢倉戦法 ''yagura senpō'') and a castle in shogi. It is usually played in a Double Static Rook opening, which is often a Double Fortress opening. However, it may also occur in different Double Static Rook openings such as Fortress vs Right Fourth File Rook. The Fortress castle (矢倉囲い ''yagura gakoi''), which is the defining characteristic of Fortress games, was considered by many to be one of the strongest defensive positions in Double Static Rook games in the 1980s. The term ''yagura'' is the Japanese word for a tower-like structure in traditional Japanese castles. Double Fortress The most commonly encountered Fortress strategies occur in Double Fortress games where both players use a Fortress formation. Historical Fortress Earlier josekis for Fortress in the Edo period (usually spelled 櫓 at that time) were very different from the current josekis. For instance, in one variation, it is ...

Transposition (chess)
In chess, a transposition is a sequence of moves that results in a position which may also be reached by another, more common sequence of moves. Transpositions are particularly common in the opening, where a given position may be reached by different sequences of moves. Players sometimes use transpositions deliberately, to avoid variations they dislike, lure opponents into unfamiliar or uncomfortable territory or simply to worry opponents. See review at In chess the verb "transpose" means to shift the game onto a different opening track from which it started. Transposition tables are an essential part of a computer chess program. Transpositions exist in other abstract strategy games such as shogi, Go, tic-tac-toe and Hex. Examples Positions reached by different routes For instance, the first position can be obtained from the Queen's Gambit: :1. d4 d5 :2. c4 e6 :3. Nc3 Nf6 But this position can also be reached from the English Opening: :1. c4 e6 :2. Nc3 Nf6 :3. d4 d5 so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direct Opposing Rook
Direct Opposing Rook (ダイレクト向かい飛車 ''dairekuto mukai hisha'') is an Opposing Rook (Ranging Rook) opening in which the player's bishop diagonal remains open allowing for a bishop trade early in the opening. Although it's classified as an Opposing Rook Ranging Rook strategy, the main characteristic is the readiness to exchange the bishop (i.e., a Ranging Rook with an open Bishop diagonal). In a typical Bishop Exchange Fourth File Rook (when playing White) the rook will move temporarily to the fourth file, and then again to the 2nd. file, with the aim of counterattacking on Black's rook pawn. The reason for the stopover on the 4th file is said to be as a way of preventing the powerful counter-attack that the Static Rook side has by dropping the bishop to 65 (or 45 in the case of White). The Direct Opposing Rook is considered a countermeasure against that B-65 move. However, in the typical Opposing Rook the rook goes from the 8th to the 2nd file (if playing White) wit ...

Sakata Opposing Rook
In shogi, Sakata Opposing Rook (阪田流向かい飛車 or 坂田流向かい飛車 ''sakata-ryū mukai hisha'') is an Opposing Rook opening. It refers to the case in a Double Static Rook situation in which Gote (White) switches energetically to an Opposing Rook variation. The origin of this strategy is dated back to the Edo period, but it was after a famous match that shogi Master Sankichi Sakata (1870-1946) played against Ichitarō Doi in May 1919, that it became popular and the opening started being named after him. Overview In a Double Static Rook situation following 1. P-76, P-34, 2. P-26, G-32, 3. P-25, Gote (White) opposes with ...B-33, 4. Bx33+, Gx33, and then by moving the rook along the 2nd. rank. There are strategies for both early fight and slow games, but still the emphasis is on constraining ( ''osaeru'') rather than on exchanging pieces (''sabaki'') which makes it easy to handle in the center. While counter-attacking by attacking Black's rook pawn is plain and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bishop Head Pawn
In shogi, the Bishop Head Pawn or Bishop's Head Pawn Push (角頭歩 or 角頭歩突き ) is a surprise opening Opening may refer to: * Al-Fatiha, "The Opening", the first chapter of the Qur'an * The Opening (album), live album by Mal Waldron * Backgammon opening * Chess opening * A title sequence or opening credits * , a term from contract bridge * , .... The opening is characterized by advancing early in the game the bishop's head pawn on 87 to 86 if played by Black or on 23 to 24 if played by White, in which it is undefended. This is a daring move since the head of the bishop (the 87 or 23 square) needs to be defended from a Static Rook attack and moving the bishop's head pawn forward increases the vulnerability of the bishop's head. It can be developed into a Ranging Rook position and is played against a Static Rook position. The opening was used by professional Kunio Yonenaga in tournament play in the 1960s and 1970s. Development 1. P-76 P-34. After ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ranging Rook Openings
Length measurement, distance measurement, or range measurement (ranging) refers to the many ways in which length, distance, or range can be measured. The most commonly used approaches are the rulers, followed by transit-time methods and the interferometer methods based upon the speed of light. For objects such as crystals and diffraction gratings, diffraction is used with X-rays and electron beams. Measurement techniques for three-dimensional structures very small in every dimension use specialized instruments such as ion microscopy coupled with intensive computer modeling. Standard rulers The ruler the simplest kind of length measurement tool: lengths are defined by printed marks or engravings on a stick. The metre was initially defined using a ruler before more accurate methods became available. Gauge blocks are a common method for precise measurement or calibration of measurement tools. For small or microscopic objects, microphotography where the length is calibrated usi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
