Fortress Opening
Fortress (矢倉 or 櫓 ''yagura'') is both a Static Rook opening (矢倉戦法 ''yagura senpō'') and a Castle (shogi), 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 (tower), 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 ins ...

Static Rook
Static Rook (居飛車 ''ibisha'') Shogi opening, openings is one of two major opening strategies in shogi. In the opening, the major piece of the rook fights from its starting position on the right side of the board (the 2nd file for Black, Sente, and the 8th file for White, Gote). In contrast, the other major opening deploys the rook to the center or left half of the board in the opening, and is known as Ranging Rook or Swinging Rook (振り飛車 furibisha). Summary Compared with Ranging Rook, leaving the rook in its starting position on the 2nd file (8th file for Gote), or in that general area on the right side, can be a more natural idea for a strategy. Although the rook does move in strategies where it's placed on the 3rd file (7th for Gote), such as with Sleeve Rook, or on the 4th file (6th for Gote), such as with Right Fourth File Rook, these openings are still broadly classified as Static Rook, rather than Ranging. The castles mainly used in Double Static Rook games are For ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 Syste ...

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.

Castle (shogi)
In shogi, are strong defensive configurations of pieces that protect the .

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.

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 open ...
