Lasker Trap
The Lasker Trap is a chess opening trap in the Albin Countergambit. It is named after Emanuel Lasker, although it was first noted by Serafino Dubois. It is unusual in that it features an underpromotion as early as the seventh move. Analysis 1. d4 d5 2. c4 e5 :The Albin Countergambit. 3. dxe5 d4 :The black pawn on d4 is stronger than it appears. 4. e3 :Careless. Usual and better is 4.Nf3. 4... Bb4+ 5. Bd2 dxe3 (see diagram) :Now White's best option is to accept doubled pawns with 6.fxe3, which the ''Encyclopaedia of Chess Openings'' gives as the best move.

Chess Opening
A chess opening or simply an opening is the initial stage of a chess game. It usually consists of established theory; the other phases are the middlegame and the endgame. Many opening sequences have standard names such as the "Sicilian Defense". ''The Oxford Companion to Chess'' lists 1,327 named openings and variants, and there are many others with varying degrees of common usage. Opening moves that are considered standard are referred to as "book moves", or simply "book". When a game begins to deviate from known opening theory, the players are said to be "out of book". In some openings, "book" lines have been worked out for over 30 moves, as in the classical King's Indian Defense and in the Najdorf variation of the Sicilian Defense. Professional chess players spend years studying openings, and continue doing so throughout their careers, as opening theory continues to evolve. Players at the club level also study openings but the importance of the opening phase is smaller t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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''.

Skewer (chess)
In chess, a skewer is an attack upon two pieces in a line and is similar to a pin. A skewer is sometimes described as a "reverse pin"; the difference is that in a skewer, the more valuable piece is the one under direct attack. The opponent is compelled to move the more valuable piece to avoid its capture, thereby exposing the less valuable piece which can then be captured (see chess piece relative value). Only (i.e. bishops, rooks, and queens) can skewer; kings, knights, and pawns cannot. Details Compared to the pin, a passive action with only an implied threat, the skewer is a direct attack upon the more valuable piece, making it generally a much more powerful and effective tactic. The victim of a skewer often cannot avoid losing ; the only question is which material will be lost. The skewer occurs less often than the pin in actual play. When it does occur, however, it is often decisive. Skewers can be broken down into two types: ''absolute'' and ''relative''. In an absolute s ...

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 . In particular, checks, , and need to be considered at each move. Neglecting these possibilities leaves a player vulnerable to simple tactical errors. One ...

Doubled Pawns
In chess, doubled pawns are two pawn (chess), pawns of the same color residing on the same Chess terminology#File, file. Pawns can become doubled only when one pawn captures onto a file on which another friendly pawn resides. In the diagram, the white pawns on the b-file and e-file are doubled. The pawns on the are doubled and isolated pawn, isolated. In most cases, doubled pawns are considered a weakness due to their inability to defend each other. This inability, in turn, makes it more difficult to achieve a breakthrough which could create a passed pawn (often a deciding factor in Chess endgame, endgames). In the case of isolated doubled pawns, these problems are only further aggravated. Several chess strategies and Chess opening, openings are based on burdening the opponent with doubled pawns, a strategic weakness. There are, however, cases where accepting doubled pawns can be advantageous because doing so may open up a file for a rook (chess), rook, or because the doubled paw ...
