Blumenfeld Countergambit
The Blumenfeld Countergambit is a chess opening characterised by the moves 3...e6 4.Nf3 b5 in the Benoni Defense arising after: :1. d4 Nf6 :2. c4 c5 :3. d5 e6 :4. Nf3 b5 or alternatively: :1. d4 Nf6 :2. c4 e6 :3. Nf3 c5 :4. d5 b5 In fact, as many as 30 different move orders are possible. The ''Encyclopaedia of Chess Openings'' sorts the Blumenfeld Countergambit under code E10 (1.d4 Nf6 2.c4 e6 3.Nf3). General considerations Black sacrifices a pawn to establish an imposing centre with pawns on c5, d5 and e6. The natural development of the bishops to b7 and d6, combined with the half-open f-file for a rook, tend to facilitate Black's play on the kingside. White, on the other hand, will typically look to counter in the centre by playing e4 at some point, while their additional queenside pawn also offers them some initiative on that side of the board. Origin The opening is named after the Russian master Benjamin Blumenfeld, and was later played by World Champio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Benoni Defense
The Benoni Defense, or simply the Benoni, is a chess opening characterized by an early reply of ...c5 against White's opening move 1.d4. The original form of the Benoni, now known as the Old Benoni, is characterized by : 1. d4 c5 This leaves Black a few options such as an early ...f5 and an early dark-squared bishop trade by ...Be7–g5, but has the drawback that White is no longer committed to playing c2–c4 after the response 2.d5. White may prefer to occupy c4 with a knight, or to inconvenience Black's development with an early bishop check on b5. More commonly, it is reached by the sequence: : 1. d4 Nf6 : 2. c4 c5 : 3. d5 Black can then offer a pawn sacrifice with 3...b5 (the Benko Gambit), otherwise 3...e6 is the most common move, leading to the Modern Benoni. 3...d6 or 3...g6 are also seen, typically transposing to main lines, or to lines of the King's Indian Defense. 3...e5, the Czech Benoni, is now considered old-fashioned and allows White a clear space advant ...

Chess Opening Theory/1
Chess is a board game for two players. It is an abstract strategy game that involves no hidden information and no elements of chance. It is played on a square board consisting of 64 squares arranged in an 8×8 grid. The players, referred to as "White" and "Black", each control sixteen pieces: one king, one queen, two rooks, two bishops, two knights, and eight pawns, with each type of piece having a different pattern of movement. An enemy piece may be captured (removed from the board) by moving one's own piece onto the square it occupies. The object of the game is to "checkmate" (threaten with inescapable capture) the enemy king. There are also several ways a game can end in a draw. The recorded history of chess goes back to at least the emergence of chaturanga—also thought to be an ancestor to similar games like and —in seventh-century India. After its introduction in Persia, it spread to the Arab world and then to Europe. The modern rules of chess emerged in Eur ...

Half-open File
In chess, a half-open file (or semi-open file) is a with pawns of only one color. The half-open file can provide a line of attack for a player's rook or queen. A half-open file is generally exploited by the player with no pawns on it. Many openings, such as the Sicilian Defense, aim to complicate the position. In the main line Sicilian, 1.e4 c5 2.Nf3 d6 (or 2...e6, or 2...Nc6) 3.d4 cxd4 4.Nxd4, White obtains a half-open d-file, but Black can pressure White along the half-open c-file. In positions where White has no pawns on a file but Black has one pawn or more on that file, the position is considered to be half-opened for White. In cases where Black has no pawns on a file but White has one or more pawns on that file, the position is considered to be half-opened for Black. A ''pawn break'' occurs when a pawn captures or advances in a way that opens or half-opens one or more files. The demolition of the pawn structure is a common theme in positions with half-open files, si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
