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
, 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] |
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. P-76 P-84 development 3.

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 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] |
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.

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 ...

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.

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 ...

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 ...
