Castle (shogi)
In shogi, are strong defensive configurations of pieces that protect the . While the English shogi term "castle" seems to be borrowed from 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 , , and . 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 Castle (shogi)#Mino, Mino castle requires moving the king, the , a silver, and two golds for a total of six moves. Others such as the Static Rook Castle (shogi)#Bear-in-the-hole, Bear-in-the-hole castle are more complex, which requires moving the king, a pawn, the , a , a silver, and two golds for a total of twelve moves. The lack of a castle an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
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] [Amazon] |
Shogi
, also known as Japanese chess, is a 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'' ). Shogi was the earliest historical chess-related 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 6th 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 a direct ancesto ...

Bishop Exchange
In shogi, Bishop Exchange () is a Double Static Rook opening in which the players exchange their bishops relatively early so as to have bishops in hand. Throughout the game, both players have a bishop drop threat, with which they can exploit any positional weakness that their opponent inadvertently creates. Overview The Bishop Exchange opening is a Double Static Rook opening. Black starts with activating both their bishop (P-76) and rook (P-26) while White quickly puts pressure on Black with rook pawn pushes (...P-84, ...P-85). White's aim is to exchange their rook pawn off the board on the eighth file as soon as possible. This has a number of benefits: it gives White a pawn in hand that can be used to drop later in the game, and it frees up the rook so that it can move to any rank above Black's camp (see: Sabaki). However, in this opening, in response, Black wishes to prevent White's early rook pawn exchange by defending the 86 square with the bishop via B-77 (and, l ...

Double Wing Attack
In shogi, Double Wing Attack or simply Wing Attack or Centre Game () is a Double Static Rook opening in which both sides directly advance their rook pawns forward on the second and eighth files toward their opponent's bishop often with the first several moves on each side being identical or very similar. Double Wing Attack, which has been played since the Edo period, has been known as a strategy prone to fierce battles due to the lack of a well-developed ''joseki''. However, with the development of computer shogi in the late 2010s including programs such as AlphaZero adopting Double Attack, there has been further progress in the ''josekis'' for this opening, which has led to its adoption in most professional title games in 2021 highlighting its importance. History and general discussion The Double Wing Attack is one of the most traditional openings dating back to over 250 years ago. Originally, unlike the Yagura (Fortress) openings, in which piece positioning advances by bl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Bishop Exchange Double Reclining Silver
In shogi, Bishop Exchange Reclining Silver or Reclining Silver With Bishops Off or Bishop Exchange Sitting Silver (角換わり腰掛け銀 ''kakugawari koshikakegin'') is a Bishop Exchange (Double Static Rook) opening that uses a Reclining Silver attacking formation. If both sides play Reclining Silver, then the position is known as Double Reclining Silver or Mutual Reclining Silver or Twin Reclining Silver (相腰掛け銀 ''aikoshikakegin''). Overview To defend the left flank against the opponent's rook pawn, Black chooses a Yagura castle form with left silver on the 77 square and the left gold on 78. Then, to avoid the risk of White's bishop drop inside Black's promotion zone, the right gold will be positioned other variously on the 58, 48 or 47 squares. According to the shogi proverb, "In the Bishop Exchange opening, don't push the central pawn." Following this, the fifth file pawn in Bishop Exchange Reclining Silver must remain on its starting 57 square in order fo ...

Ōi (shogi)
is one of the eight major titles in professional shogi, and it means "the king's rank" (王 ''ō'' 'king' + 位 ''i'' 'rank, position'). Background The annual tournament started in 1960, sponsored by a group of local newspapers which has consisted of Shimbun Sansha Rengō (Three-Newspaper Association). With the addition of Ōi, there were four major shogi titles along with Meijin, Ninth Dan ( Ryūō), and Ōshō.

Right King
In shogi, Right King or Right-hand King (右玉 ''migi gyoku'') is a defensive subcomponent of different openings in which the king stays on the right side of the board together with the rook, which protects the back rank (rank 9) as well as the eighth file. It is an exception to the general rule that the king is castled away from the rook. It is possible to use a Right King formation within a Bishop Exchange opening as well as other openings. The castle formation used in these strategies is also called a Right King castle. Overview When an opponent is building up a Static Rook position, castling the king to the left means that the player will need to defend from attacks from above. However, were the king to be placed in the right, far away from the opponent's attack, the efficacy of such an attack could be diminished. As for variations in right king, in the case where a castle has been built on the left flank, the opponent will expect that the king will transfer to the le ...

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 Whit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
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 (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 ...
