Karel Traxler
Karel Traxler (1866 – 1936) was a Czech chess master and composer of chess problems. He is best known for the hyper-aggressive variation named after him, the Traxler Variation in the Two Knights Defense. Traxler Variation The Traxler Variation was first shown in the following game against Reinisch, played in Hostouň in 1890: Problem composer Because Traxler was a Roman Catholic priest, he rarely played chess in serious competitions. As a composer of chess problems he pursued the style of Bohemian school. He wrote under a number of pseudonyms: Anonymus z Tábora, Karel Kaplan, Vis Maior und Karel Zboněk.

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 a safe square, interposing a piece between the threatening piece and the king, or capturing the threatening piece. If the player cannot get out of check by any of these options, the game ends in checkmate, and the player loses. Players cannot make any move that puts their own king in check. Many chess variants feature check, such as shogi, xiangqi, and janggi. Overview A check is the result of a move that places the opposing king under an immediate threat of capture by one (or occasionally 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, White has just played Be4+, simultane ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Discovered Check
In chess, a discovered attack is a direct attack revealed when one piece moves out of the way of another. Discovered attacks can be extremely powerful, as the piece moved can make a threat independently of the piece it reveals. Like many chess tactics, they often succeed because the opponent would be unable to meet two threats at once unless one of the attacked pieces can simultaneously move away from its own attack and capture the other attacking piece. While typically the consequence of a discovered attack is the gain of , they do not have to do this to be effective; the tactic can be used merely to gain a tempo. at MarkLowery.net If the discovered attack is a |
Undermining (chess)
Undermining (also known as removal of the guard, or removing the defender) is a chess tactic in which a defensive piece is captured, leaving one of the opponent's pieces undefended or under-defended. The opponent has the unpalatable choice of recapturing or saving the undefended piece. A possible response is to sacrifice the piece whose defense was undermined before capturing the piece which just took the defender. Example Kramnik– Topalov in the seventh round of the 2004 Linares chess tournament reached the diagrammed position with White to play. The black knight on a4 is defended only by the black pawn on b5. White undermined the knight with 1. Bxb5. The game continued 1... Rxb5 2. Rxa4, with a net gain of a pawn for White. Black may attempt 1...Nxb2??, disposing of the unguarded knight and hoping for 2.Kxb2 Rxb5+ to regain the lost pawn. However, after 2.Rb3 Black can only save the knight with 2…Rxb5 3.Rxb5, leaving White an exchange up instead of just a pawn. See als ...

Fork (chess)
In chess, a fork is a tactic in which a piece multiple enemy pieces simultaneously. The attacker usually aims to capture one of the forked pieces. The defender often cannot counter every threat. A fork is most effective when it is forcing, such as when the king is put in check. A fork is a type of . Terminology A fork is an example of a . The type of fork is named after the type of forking piece. For example, a fork by a knight is a knight fork. The attacked pieces are ''forked''. If the King is one of the attacked pieces, the term ''absolute fork'' is sometimes used. A fork not involving the enemy king is in contrast a ''relative fork''. A fork of the king and queen, the highest material-gaining fork possible, is sometimes called a ''royal fork''. A fork of the enemy king, queen, and one (or both) rooks is sometimes called a ''grand fork''. A knight fork of the enemy king, queen, and possibly other pieces is sometimes called a ''family fork'' or ''family check''. Strategy ...

Two Knights Defense
The Two Knights Defense is a chess opening that begins with the moves: :1. e4 e5 :2. Nf3 Nc6 :3. Bc4 Nf6 First recorded by Giulio Cesare Polerio (c. 1550 – c. 1610) in the late 16th century, this line of the Italian Game was extensively developed in the 19th century. Black's third move is a more aggressive defense than the Giuoco Piano ( 3...Bc5). Black invites White to attack his f7-pawn with 4.Ng5. If White accepts the offer, the game quickly takes on a tactical character: Black is practically to give up a pawn for the initiative. The complications are such that David Bronstein suggested that the term "defense" does not fit, and that the name "Chigorin Counterattack" would be more appropriate. The Two Knights has been adopted as Black by many aggressive players including Mikhail Chigorin and Paul Keres, and world champions Mikhail Tal and Boris Spassky. In modern grandmaster play, 3.Bc4 is less common than 3.Bb5, and the more solid 3...Bc5 is the most frequent rep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
