Yagura 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 W ...

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 (However, some ''s'' have become outdated when they are reevaluated to no longer give balanced play.)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) ...

Central Rook Fortress
Central Rook Fortress (矢倉中飛車 ''yagura nakabisha'') is a Double Fortress (Double Static Rook) shogi opening. This strategy characteristically swings the player's rook to the central file to support an attack there. Central Rook Fortress should not be confused with Yagura's Central Rook (矢倉流中飛車 ''yagura-ryuu nakabisha'') which is an unrelated Central Rook strategy named after professional player Norihiro Yagura.

Shogi Openings
, also known as Japanese chess, is a Abstract strategy game, 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 chess, 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 Mercenary#15th to 18th centuries, 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".

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 Vs Right Fourth File Rook
Fortress vs Right Fourth File Rook (矢倉対右四間飛車) is a Double Static Rook opening in which one player chooses a Fortress position and their opponent uses a Right Fourth File Rook In shogi, Right Fourth File Rook (右四間飛車 ''migi shikenbisha'') is a Static Rook opening in which the rook is positioned on the fourth file if played by Black or the sixth file if played by White. Typically, Right Fourth File Rook develo ... position. Development Another Double Static Rook game includes playing Right Fourth File Rook against a Fortress position. If White is going to attempt Right Fourth File Rook, then after Black advances their central pawn on the fifth move, White should push their rook pawn to the central file forcing White to protect the second with their silver. After this, White starts developing the Right Fourth File Rook structure by advancing their sixth file pawn (that is, their pawn that is the fourth file from the right side of their ...

Crab Silvers
The Crab Silvers (カニカニ銀 ''kani kani gin'') is a shogi opening. It is a type of Rapid Attack Fortress opening, used mostly when playing Black (sente). It is often classified as a trap opening. It was created by professional shogi player Kōichi Kodama, for which he received the prestigious Kōzō Masuda Award in 2003. Overview Due to the large amount of freedom of the rook to enter into the game, finding ways to attack even in the middle of a Rapid Attack Fortress has quite the merit. Unlike the Double-Silver Rapid Attack Fortress, king and gold don't move at all from their initial position (Sitting king). In the fifth movement, rather than pushing P-66, the silver is pushed to S-77. Instead of opting not to push the rook pawn from Fortress, White (gote) will play S-33 following Black's rook pawn being pushed to P-25, which will be followed by ▲S-48, ▲P-56, ▲S-57, ▲S-46. After that, if White (gote) were to push the pawn in the 5th file, the rook will go to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Akutsu Rapid Attack Fortress
In shogi, Akutsu Rapid Attack Fortress (阿久津流急戦矢倉 ''akutsu-ryū kyūsen yagura'') is a Double Fortress (Static Rook) opening. This style of Fortress was named after professional player Chikara Akutsu who has used this strategy with good results. Akutsu Rapid Attack Fortress is typically used by White. It is characterized by White keeping their bishop diagonal open so that the central file pawns may be exchanged. Following the pawn exchange on the fifth file with the bishop, the goal of White is to build a good position with their right silver advanced to the 54 square, so as to later start the fight on the sixth file with a pawn push (☖P-65). The bishop on the 55 square can be pulled back on White's right side to the 73 square or returned its starting square on 22. Depending on Black's response, the goal mentioned above is often rejected and there's a shift to a slow game. See also * Fortress opening * Morishita System * Spearing the Sparrow * Waki System * ...

Right Fourth File Rook
In shogi, Right Fourth File Rook (右四間飛車 ''migi shikenbisha'') is a Static Rook opening in which the rook is positioned on the fourth file if played by Black or the sixth file if played by White. Typically, Right Fourth File Rook develops the right silver into a Reclining Silver attacking structure. Fortress vs Right Fourth File Rook Right Fourth File Rook vs Fourth File Rook A Right Fourth File Rook strategy may be played against a Ranging Rook position such as Fourth File Rook. In a Right Fourth File Rook vs Fourth File Rook game, each player's rook will be directly opposing each other on the fourth file supported by attacking silvers. Below shows an example of Black's Right Fourth File Rook against White's Fourth File Rook. 1. P-76 P-34, 2. P-26 P-44, 3. S-48 R-42. The first six moves are standard Static Rook vs Fourth File Rook piece development. (See: Left Silver-57 Rapid Attack vs Fourth File Rook for explication.) 4. P-46. The Right Fourth Fil ...

Castle (shogi)
In shogi, castles ( ja, 囲い, translit=kakoi) are strong defensive configurations of pieces that protect the king ( ja, 玉). In contrast to the special castling move in western chess, shogi castles are structures that require making multiple individual moves with more than one piece. Introduction Usually the pieces involved in constructing castles are golds ( ja, 金), silvers ( ja, 銀), and pawns ( ja, 歩). Typically, they also require moving the king from its starting position – often to the left or right side of the board. The simplest castle involves two pieces and requires three moves, but it is more common to move at least three different pieces. For example, a simple Mino castle requires moving the king, the rook ( ja, 飛), a silver, and two golds for a total of six moves. Others such as the Static Rook Bear-in-the-hole castle are more complex, which requires moving the king, a pawn, the bishop ( ja, 角), a lance ( ja, 香), a silver, and two golds for a ...

Snowroof
In shogi, Snowroof or Snow Roof Fortress (雁木 ''gangi'', lit. 'goose-wooden') is a Static Rook opening that characteristically uses a Snowroof castle. It is named after the covered sidewalks (雁木造) connected to buildings in Niigata Prefecture. Originating in the Edo period, the opening had been a less common one after World War II although it was popular in the prewar era. However, around 2017, the opening has become popular with professional shogi players. The Snowroof structure often appears in computer shogi games. Characteristics For Black, this castle positions the king on the 69 square while two golds are at the ears of king (78, 58) and the two silvers are on 67 and 57. The Snowroof castle is strong against attacks directly from above, especially attacks around the central file. Naitō (1981) notes that the Snowroof was once very popular and had a reputation for being very difficult for a Fortress opponent to defeat. However, by 1981, the Snowroof ...
