Double Fortress
The Double Fortress (相矢倉 or 相櫓 ''aiyagura'') is a shogi opening in which both players construct Fortress formations. Double Fortress games are the most common type of Fortress games found at all levels of play. Historical Fortress Earlier josekis for Fortress in the Edo period (usually spelled 櫓 at that time) were very different from the current josekis. In one variation, White delays pushing their rook pawn (whereas Black delays the rook pawn push in the modern era) and there is an early bishop trade before both players' kings are moved into their castles. In the 1947 Meijin tournament, Masao Tsukada and Yoshio Kimura played an early example of the typical 3. S-77 type of Fortress with 1.P-76 P-84 development found in modern shogi. 1.

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.

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".

日本将棋連盟
The , or JSA, is the primary organizing body for professional shogi in Japan. The JSA sets the professional calendar, negotiates sponsorship and media promotion deals, helps organize tournaments and title matches, publishes shogi-related materials, supervises and trains apprentice professionals as well as many other activities. History For much of its early history, shogi followed an iemoto system centered around three families (schools): the , the and the . The Meijin title was hereditary and could only be held by members of these three families. These three schools were supported by the Tokugawa shogunate and thus controlled the professional shogi world up until 1868 when the Meiji Restoration began. By the time , the eighth and last head of the Itō school and the 11th Hereditary Meijin, had died in 1893, the influence of the families had decreased to such an extent that they had no real power at all. In 1921, there were three groups of professional players in the Tokyo ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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.

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) ...

Akutsu Rapid Attack Yagura
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 Sys ...
