Bogo-Indian Defence
The Bogo-Indian Defence is a chess opening characterised by the moves: :1. d4 Nf6 :2. c4 e6 :3. Nf3 Bb4+ The position after 1.d4 Nf6 2.c4 e6 is common. The traditional move for White here is 3.Nc3, threatening to set up a big pawn centre with 4.e4. However, 3.Nf3 is often played instead as a way of avoiding the Nimzo-Indian Defence (which would follow after 3.Nc3 Bb4). After 3.Nf3, Black usually plays 3...b6 (the Queen's Indian Defence) or 3...d5 (transposing to the Queen's Gambit Declined), but can instead play 3...Bb4+, the Bogo-Indian Defence. Databases suggest that the Bogo-Indian is played approximately half as often as the Queen's Indian. The Bogo-Indian Defence can also arise via the move order 1.d4 e6 2.c4 Bb4+, the Keres Defence. The Bogo-Indian is classified as E11 by the ''Encyclopaedia of Chess Openings'' (ECO). History The Bogo-Indian Defence is named after the Russian-born German master Efim Bogoljubow who is believed to have originated the opening and ...

Monticelli Trap
In chess, the Monticelli Trap is a combination in the Bogo–Indian Defence, named for Italian champion Mario Monticelli from the game Monticelli versus Prokeš, Budapest 1926. Although it is called a trap because White wins the exchange, Black does obtain some compensation. The trap begins with the moves: :1. d4 Nf6 :2. c4 e6 :3. Nf3 Bb4+ ::Black plays the Bogo–Indian Defence. :4. Bd2 Bxd2+ :5. Qxd2 b6 :6. g3 Bb7 :7. Bg2 O-O :8. Nc3 Ne4 :9. Qc2 Nxc3 :10. Ng5! (see diagram) Discussion White threatens mate with 11.Qxh7# as well as 11.Bxb7 winning a bishop and a rook. After either 10...Ne4 11.Bxe4 or 10...Qxg5 11.Bxb7, Black loses the exchange, but obtains compensation in the form of one or more pawns and possibly a weakened white king. It is unclear if the position is a forced win for White. Former world champion José Raúl Capablanca allowed 10.Ng5 twice in consecutive games as Black against Max Euwe in Amsterdam, 1931, drawing both times. The second gam ...

Knight (chess)
The knight (♘, ♞) is a piece in the game of chess, represented by a horse's head and neck. It moves two squares vertically and one square horizontally, or two squares horizontally and one square vertically, jumping over other pieces. Each player starts the game with two knights on the b- and g-, each located between a rook and a bishop. Movement Compared to other chess pieces, the knight's movement is unique: it moves two squares vertically and one square horizontally, or two squares horizontally and one square vertically (with both forming the shape of a capital L). Consequently, a knight alternates between light and dark squares with each move. When moving, the knight can jump over pieces to reach its destination. Knights capture in the same way, replacing the enemy piece on the square and removing it from the board. A knight can have up to eight available moves at once. Knights and pawns are the only pieces that can be moved in the chess starting position. Val ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bishop (chess)
The bishop (♗, ♝) is a Chess piece, piece in the game of chess. It moves and captures along without jumping over interfering pieces. Each player begins the game with two bishops.

Placement and movement The is placed on f1 for White and f8 for Black; the is placed on c1 for White and c8 for Black. The bishop has no restrictions in distance for each move but is limited to diagonal movement. It cannot jump over other pieces. A bishop captures by occupying the square on which an enemy piece stands. As a consequence of its diagonal movement, each bishop always remains on one square color. Due to this, it is common to refer to a bishop as a ''light-squared'' or ''dark-squared'' bishop. Comparison – other pieces Versus rook A rook (chess), rook is generally worth about two Pawn (chess), pawns more than a bishop. The bishop has access to only half of the squares on the board, w ...

Transposition (chess)
In chess, a transposition is a sequence of moves that results in a position that 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 To transpose is to play a move that results in a transposition. 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. Examples Positions reached by different routes For instance, the first position can be obtained from the Queen's Gambit: :1. d4 d5 :2. c4 e6 :3. Nc3 Nf6 But this position can also be reached from the English Opening: :1. c4 e6 :2. Nc3 Nf6 :3. d4 d5 so the English Opening has transposed into the ...

Check (chess)
In chess and similar games, check is a condition that occurs when a player's king is under threat of on the opponent's next turn. A king so threatened is said to be ''in check''. A player must get out of check if possible by moving the king to an unattacked square, interposing a piece between the threatening piece and the king, or capturing the threatening piece. If the player cannot remove the check by any of these options, or if using any of these options would result in the player being in check by another piece, the game ends in checkmate and the player loses. Players cannot make any move that puts their own king in check. Overview A check is the result of a move that places the opposing king under an immediate threat of capture by one (or, in rare cases, two) of the player's pieces. Making a move that checks is sometimes called "giving check". Even if a piece is pinned against the player's own king, it may still give check. For example, in the diagrammed position ...
