Shogi Strategy
Shogi, like western chess, can be divided into the opening, middle game and endgame, each requiring a different strategy. The opening consists of arranging one's defenses and positioning for attack, the middle game consists of attempting to break through the opposing defenses while maintaining one's own, and the endgame starts when one side's defenses have been compromised. Tactics Many basic tactics (手筋 ''tesuji'') of shogi are similar to those of chess tactics, involving forks, pins, removing the defender and other techniques, all of which are considered very strong when used effectively. However, other tactics, particularly ones involving dropped pieces, have no parallel in western chess. Relative piece value Shogi pieces may be considered to have different valuations in which some pieces are generally more ''valuable'' than others – all other things being equal. (Cf. piece value in western chess.) There are three main valuation groups: # the king which has an abso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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".

Go (game)
Go is an abstract strategy board game for two players in which the aim is to surround more territory than the opponent. The game was invented in China more than 2,500 years ago and is believed to be the oldest board game continuously played to the present day. A 2016 survey by the International Go Federation's 75 member nations found that there are over 46 million people worldwide who know how to play Go and over 20 million current players, the majority of whom live in East Asia. The playing pieces are called stones. One player uses the white stones and the other, black. The players take turns placing the stones on the vacant intersections (''points'') of a board. Once placed on the board, stones may not be moved, but stones are removed from the board if the stone (or group of stones) is surrounded by opposing stones on all orthogonally adjacent points, in which case the stone or group is ''captured''. The game proceeds until neither player wishes to make another move. Wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tsume Shogi
or tsume (詰め) is the Japanese term for a shogi miniature problem in which the goal is to checkmate the opponent's king. Tsume problems usually present a situation that might occur in a shogi game (although unrealistic artistic tsume shogi exists), and the solver must find out how to achieve checkmate. It is similar to a mate-in-''n'' chess problem. The term tsumi (詰み) means the state of checkmate itself. The verb form is tsumu (詰む) "to checkmate". (The related term ''tsumero'' 詰めろ refers to the slightly different concept of "threatmate". See: Hisshi.) ''Tsume shogi'' problems are strictly forced mate problems with constant checks. They assume that the player is in brinkmate and that they will lose unless they can force a mate sequence with a check on every move. The situation simulates real shogi games in which the endgame is essentially a mutual mating race. Note that the concept of stalemate as in western chess does not exist in shogi as it essentially does ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castle (shogi)
In shogi, castles ( ja, 囲い, translit=kakoi) are strong defensive configurations of pieces that protect the king ( ja, 玉). In contrast to 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 golds ( ja, 金), silvers ( ja, 銀), and pawns ( ja, 歩). 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 Mino castle requires moving the king, the rook ( ja, 飛), a silver, and two golds for a total of six moves. Others such as the Static Rook Bear-in-the-hole castle are more complex, which requires moving the king, a pawn, the bishop ( ja, 角), a lance ( ja, 香), a silver, and two golds for a ...

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) ...

Brinkmate
Brinkmate is the situation in which an unavoidable checkmate sequence will be created by the player's next move. In shogi, brinkmate is known as hisshi (必至 "desperation, inevitability" or 必死 "sure kill"). Note that in shogi ''tsume'' is defined as strictly forced mate sequences with constant checks. The checkmating sequence itself (after the brinkmate) is known as a 詰め ''tsume.'' Brinkmate differs from the situation in which a checkmate sequence is only being threatened to be created in the next move but is still avoidable if the opponent defends correctly. This situation is known as threatmate or, in Japanese, 詰めろ tsumero ("threatened mate"). Thus, brinkmate is an indefensible threatmate. The only way to prevent a loss from a brinkmate is for the defender to not give their opponent a chance to actually create the checkmate sequence and instead initiate their own mating sequence (with constant checks) before their opponent's move. (Thus, a good exemplification of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bear-in-the-hole Castle
The Bear-in-the-hole or Anaguma castle (穴熊 ''anaguma'', badger, lit. "hole-bear") is a castle used in shogi. (An anaguma is a Japanese badger.) It is commonly used in professional shogi. History The Bear-in-the-hole was initially a castle used by Ranging Rook players. In modern times, it was at first considered a poor choice for Ranging Rook. Additionally, the renaissance of Ranging Rook strategies that was happening in the first part of the 20th century was in part attributed to the strength of the Mino castle. However, a Static Rook strategy – the King's Head Vanguard Pawn – became a formidable challenge to Ranging Rook positions, as the Mino castle is weak against frontal attacks and the King's Head Vanguard Pawn strategy exploits these weaknesses by attacking the Mino from above. Therefore, a change from a Mino to a Bear-in-the-hole was considered since the Ranging Rook player's king is moved one rank further away from the vanguard pawn offense. The Bear-in- ...

Fujii System
In shogi, the Fujii System (藤井システム ''fujii shisutemu'') is a set of Fourth File Rook strategies used against various Static Rook strategies. It was created as a way to attack Static Rook Anaguma castle positions. It is named after Takeshi Fujii who invented the strategies, which awarded him the prestigious Kōzō Masuda Award in 1998. The system can also be applied for Third File Rook strategies. Overview The Fujii system is a set of strategies for Fourth and Third File Rook openings developed by Takeshi Fujii. In particular, the Fujii System attracted a good deal of attention as a countermeasure against Static Rook Anaguma with Fujii himself playing a prominent role. As described below, the Fujii System includes countermeasures against Left Mino castles as well as Anaguma castles. In the latter case, characteristically, if the opponent is aiming for an Anaguma, the strategy consists of initiating a fight before the king can be completely castled into the Anaguma ...

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] |
