Bishop Exchange
In shogi, Bishop Exchange (角換わり or 角換り ''kakugawari'') 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 ... [...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".

Transposition (chess)
In chess, a transposition is a sequence of moves that results in a position which may also be reached by another, more common sequence of moves. Transpositions are particularly common in the opening, where a given position may be reached by different sequences of moves. Players sometimes use transpositions deliberately, to avoid variations they dislike, lure opponents into unfamiliar or uncomfortable territory or simply to worry opponents. See review at In chess the verb "transpose" means to shift the game onto a different opening track from which it started. Transposition tables are an essential part of a computer chess program. Transpositions exist in other abstract strategy games such as shogi, Go, tic-tac-toe and Hex.

Nc3 Nf6 But this position can also be reached from the English Opening: :1. c4 e6 :2. Nc3 Nf6 :3. d4 d5 so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Blunder (chess)
In chess, a blunder is a critically bad move. It is usually caused by some tactical oversight, whether it be from time trouble, overconfidence or carelessness. Although blunders are most common in amateur 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 a double question mark, "", after the move. Especially among amateur and novice players, blunders often occur because of a faulty thought process where players do not consider the opponent's .
