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 (However, some ''s'' have become outdated when they are reevaluated to no longer give balanced play.)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

Fortress Castle
Fortress or Yagura (矢倉囲い or 櫓囲い ''yaguragakoi'') is a castle used in shogi. It is considered by many to be the strongest defensive position in shogi in Double Static Rook games. The most common form of Fortress is the Gold Fortress. Besides the Gold Fortress, there are many variant forms. And, there are development relations between Fortress and other castles. For instance, the Crab castle can be developed into a Gold Fortress, and the Gold Fortress can be developed into a Fortress Anaguma. ''Fortress'' is also the name of an opening strategy that uses a Fortress castle (see: Fortress opening). When used in the Fortress opening, the bishop, rook, and a pawn all support a later attack by the rook's silver or knight. Variants of the Fortress are also used in other Double Static Rook games (for instance, Bishop Exchange) as well as in Static Rook vs Ranging Rook games and in Double Ranging Rook games.

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 ...

Morishita System
In shogi, the Morishita System (森下システム ''morishita shisutemu'') is a strategy used by Black in Double Fortress (Static Rook) openings. The strategy was invented by professional player Taku Morishita for which he won the prestigious Kōzō Masuda shogi award. Morishita himself has described it as a way of thinking rather than a specific strategy. Hitoshige Awaji and Teruichi Aono are well known for their efforts to systematize it. Overview The accompanying diagram shows the basic position. The Morishita System delays moving the right attacking silver to 37 early. Instead, it simply moves the bishop to 68 allowing the king to move into the Fortress castle in subsequent moves. The position continues with Black's N-37, B-64, and P-26. While it is traditionally said in shogi that Fortress is a position in which "Black decides the position while White deals with it," in this strategy this is intentionally reversed. It can be said that the way of thinking is that with 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 * ...

Waki System
In shogi, Waki System (脇システム ''waki shisutemu'') is a symmetrical Double Fortress (Static Rook) opening. It is characterized in part by positioning Black's bishop on the 46 square and White's bishop on the 64 square allowing for a bishop exchange. The strategy is named after Kenji Waki. Development An early ...P-74 (as opposed to an early ...G-52) is the most common move leading to the standard 24-Move Fortress Set (矢倉24手組) position, which is one of the major branching points of the set of Fortress substrategies. 13. S-37. The Waki System is a silver-37 branch Fortress substrategy. 13. ...B-64. The Waki System form starts with White moving their bishop to 64 temporarily pinning Black's silver to their rook. 14.

Spearing The Sparrow
In shogi, Spearing the Sparrow (雀刺し or スズメ刺し ''suzumezashi'') is one of the substrategies of the Fortress (Static Rook) class of openings. The strategy is basically an edge attack on the first file if played by Black or the ninth file if played by White. The player's rook characteristically moves to the respective edge file to support an attack there along with the right knight, the edge pawn, the right lance, and the bishop.

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 ...

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 ...

Central Rook
In shogi, Central Rook (中飛車 ''nakabisha'') is a subclass of Ranging Rook openings in which the rook is positioned on the fifth (central) file. However, since the central file can be thought of as the dividing line between Ranging Rook and Static Rook positions, it is also possible to find Static Rook positions using a rook that has been moved to the central file. These strategies are generally categorized as subclasses of the particular Static Rook opening. For example, Central Rook Yagura (矢倉中飛車) is a Yagura opening that uses a central rook. The term 中飛車 without modification refers to Ranging Rook Central Rook strategies while Static Rook central rook strategies have another word modifying 中飛車. Central Rook subcategories Ranging Rook strategies like Central Rook are also traditionally played by White against Black's Static Rook position. However, in the modern era (that is, later than the Edo period), Normal Central Rook is played by both White a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
