Ruy Lopez, Exchange Variation
The Exchange Variation of the Ruy Lopez is a chess opening that begins with the moves: :1. e4 e5 :2. Nf3 Nc6 :3. Bb5 a6 :4. Bxc6 Black may recapture on c6 with either pawn; although 4...bxc6 is playable, 4...dxc6 is almost always chosen at master level. Black has gained the at the cost of a weakened pawn structure, having doubled pawns on c6 and c7. White aims to reach an endgame with a superior pawn structure, which may become an important factor. Thus, Black is compelled to strive for an active position, generally avoiding piece exchanges. The variation was introduced into grandmaster play by Emanuel Lasker, and later invigorated with new ideas by Bobby Fischer. The Exchange Variation can be a powerful psychological weapon. Black is forced to play actively, which is psychologically difficult if all one needs is a draw. Lasker's famous win against Jose Raul Capablanca in the St. Petersburg 1914 chess tournament is an example of this. With a lead in the tournament, Cap ...

Ruy López De Segura
Rodrigo "Ruy" López de Segura (c. 1530 – c. 1580) was a Spanish chess player, author, and Catholic priest whose 1561 treatise '' Libro de la invención liberal y Arte del juego del Axedrez'' was one of the first books about modern chess in Europe. He made great contributions to chess opening theory, including in the King's Gambit and the Ruy López (or Spanish) opening that bears his name. López was also the strongest player in Spain for about 20 years. Life López was a native of Segura de León, a town in Extremadura, Spain. In 1559, while living in Zafra, López was called to Rome by Pope Pius IV on ecclesiastical business. During his stay in Rome, López played chess with the locals. He apparently acquitted himself well, although the only account of these games is given in a single sentence by López himself. One of those players was ''Il Puttino'', an epithet for a young Leonardo di Bona. López also learned the term ''gambit'' from the Italian players. In Italy ...

Johan Barendregt
Johan Teunis Barendregt (16 February 1924 – 2 January 1982) was a Dutch psychologist and chess International Master (IM) (1962). Psychologist Barendregt studied psychology at the University of Amsterdam with Adriaan de Groot and investigated the effectiveness of psychoanalysis, among other things. He had the ambition to force psychology in the direction of natural science and, according to his contemporaries, delivered a methodologically exemplary dissertation, covering only 53 pages. From 1962 he was a professor at the University of Amsterdam. His model for the development of a phobia was published posthumously. Barendregt argued that a phobia arises from what he called "it", an acute attack of depersonalization, in which the phobia has a survival function; the "foothold is found in fear, which is preferable to emptiness." In retrospect by Jaap van Heerden, Barendregt is called 'a walking paradox', because he became the personification of the method struggle that was going o ...

Promotion (chess)
In chess, promotion is the replacement of a pawn with a new piece when the pawn is moved to its last . The player replaces the pawn immediately with a queen, rook, bishop, or knight of the same . The new piece does not have to be a previously captured piece. Promotion is mandatory; the pawn cannot remain as a pawn. Promotion to a queen is known as queening; promotion to any other piece is known as underpromotion. Promotion is almost always to a queen, as it is the most powerful piece. Underpromotion might be done for various reasons, such as to avoid stalemate or for tactical reasons related to the knight's unique movement pattern. Promotion or the threat of it often decides the result in an endgame. Rules When a pawn is promoted, it is removed from the board, and the new piece is placed on the square of promotion. A piece may be promoted to regardless of whether it has been captured. Consequently, a player might have two or more queens, or three or more rooks, bishops, or kni ...

Passed Pawn
In chess, a passed pawn is a pawn with no opposing pawns to prevent it from advancing to the eighth ; i.e. there are no opposing pawns in front of it on either the same or adjacent files. A passed pawn is sometimes colloquially called a ''passer''. Passed pawns are advantageous because only the opponent's pieces can stop them from promoting. In the diagram, the white pawns on b5, c4, and e5 are passed pawns, and Black's pawn on d4 is a passed pawn. If Black plays ...fxg4, then the black pawn on g4 will be passed, as well as White's pawn on f4. Protected passed pawn A passed pawn that is protected by its own pawns is called a ''protected passed pawn''. In the first diagram in this article, the pawns on the b- and e-files are protected passed pawns. Two or more passed pawns on adjacent files are called ''connected passed pawns'' (see connected pawns), and they are very strong. In the diagram at the top, White's b- and c-pawns are connected passed pawns. A pair of connec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chess Endgame
In chess and other similar games, the endgame (or end game or ending) is the stage of the game when few pieces are left on the board. The line between middlegame and endgame is often not clear, and may occur gradually or with the quick exchange of a few pairs of pieces. The endgame, however, tends to have different characteristics from the middlegame, and the players have correspondingly different strategic concerns. In particular, pawns become more important as endgames often revolve around attempting to promote a pawn by advancing it to the eighth . The king, which normally should stay hidden during the game should become active in the endgame, as it can help escort pawns to the promotion square, attack enemy pawns, protect other pieces, and restrict the movement of the enemy king. All chess positions with up to seven pieces on the board have been solved, that is, the outcome (win, loss, or draw) of best play by both sides is known, and textbooks and reference works teach th ...

Discovered Attack
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 |

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] |
Checkmate
Checkmate (often shortened to mate) is any game position in chess and other chess-like games in which a player's king is in check (threatened with ) and there is no possible escape. Checkmating the opponent wins the game. In chess, the king is never actually captured—the player loses as soon as the player's king is checkmated. In formal games, it is usually considered good etiquette to resign an inevitably lost game before being checkmated. If a player is not in check but has no legal move, then it is '' stalemate'', and the game immediately ends in a draw. A checkmating move is recorded in algebraic notation using the hash symbol "#", for example: 34.Qg3#. Examples A checkmate may occur in as few as two moves on one side with all of the pieces still on the board (as in Fool's mate, in the opening phase of the game), in a middlegame position (as in the 1956 game called the Game of the Century between Donald Byrne and Bobby Fischer), or after many moves with as few as t ...
