Tsumeshogi
or tsume (詰め) is the Japanese language, 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 ...

Shogi Notation
Shogi notation is the set of various abbreviatory notational systems used to describe the piece movements of a shogi game record or the positions of pieces on a shogi board. A record of an abstract strategy game, abstract strategy board game such as shogi is called in Japanese. Recording moves Western notation The system used in English language texts to express shogi moves was established by George Hodges (shogi), George Hodges and Glyndon Townhill in 1976 by the second issue of ''Shogi'' magazine. A slightly modified version was used in . It is derived from the Algebraic chess notation, algebraic notation used for chess, but differs in several respects. A typical move might be notated P86 or P-8f. The notation format has the following 5 part structure: : An example using all 5 parts is S72x83+ or S7bx8c+. All parts are obligatory except for the ''origin'' and ''promotion'' parts. (Thus, most notation strings only contain 3 parts.) The ''origin'' part is only indicated ...

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 ...

Hisshi
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 o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Cheerful Central Rook
In shogi, Cheerful Central Rook (ゴキゲン中飛車 ''gokigen nakabisha'', also Gokigen Central Rook or Go-As-You-Please Central Rook) is a type of Central Rook opening in which the Central Rook player's bishop diagonal remains open. This is a more aggressive strategy since the bishops may be exchanged at any time during the opening. (See: Ranging Rook#Types of Ranging Rook.) Cheerful Central Rook is played against a Static Rook opponent. White's variation 1.P-76 P-34 2.P-26. Open bishop diagonals. Black plays Static Rook. 2...P-54. White pushes the central pawn – the signature move of Cheerful Central Rook. 3.P-25. Rook pawn advance. 3...R-52. Central Rook move. Early pawn push After White swings their rook to the central file, pushing the second file pawn by Black (4.P-24) in order to trade the pawns off and get a pawn in hand is thought to be a mistake (although not quite a blunder) here since it will result in a position judged to be better for ...

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] [Amazon] |

Fool's Mate
The Fool's mate is the fastest checkmate in chess delivered after the fewest possible moves from the game's starting position. It arises from the following moves (minor variations are possible): :1. f3 e6 :2. g4?? Qh4 The mate can be achieved in two moves only by Black, giving checkmate on the second move with the queen. Fool's mate received its name because it can occur only if White commits an extraordinary blunder. Black can be mated in an analogous way, although this requires an additional move, with White's queen delivering checkmate on the third move. Even among rank beginners, this checkmate rarely occurs in practice. The mate is an illustration of the weakness shared by both players along the f- and g- during the opening phase of the game. A player may also suffer an early checkmate if the f- and g-pawns are advanced prematurely and the kingside is not properly defended, as shown in historical games recorded in chess literature. History Fool's mate was named and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Blunder (chess)
In chess, a blunder is a critically bad mistake that severely worsens the player's position by allowing a loss of , checkmate, or anything similar. It is usually caused by some tactical oversight, whether due to time trouble, overconfidence, or carelessness. Although blunders are most common in beginner games, all human players make them, even at the world championship level. Creating opportunities for the opponent to blunder is an important skill in chess. What qualifies as a blunder rather than a normal mistake is somewhat subjective. A weak move from a novice player might be explained by the player's lack of skill, while the same move from a master might be called a blunder. In chess annotation, blunders are typically marked with two question marks ("??") after the move notation. Especially among amateur and novice players, blunders often occur because of a faulty thought process where players do not consider the opponent's . In particular, checks, , and need to be considere ... [...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] |
