Lucena Position
The Lucena position is a position in chess endgame theory where one side has a rook and a pawn and the defender has a rook. Karsten Müller said that it may be the most important position in endgame theory. It is fundamental in the rook and pawn versus rook endgame. If the side with the pawn can reach this type of position, they can forcibly win the game. Most rook and pawn versus rook endgames reach either the Lucena position (with the King of the stronger side in front of the pawn) or the Philidor position (with the defending King in front of the pawn) if played accurately. The side with the pawn will try to reach the Lucena position to win; the other side will try to reach the Philidor position to draw. Rook and any number of pawns endgames, which occur in 8–10% of all games, may simplify to the Lucena position. As it is a known win, the player with the pawn will often try to reach the Lucena position, while the other player will try to prevent it. There is an alternate ...

Chess Kll45
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Handbuch Des Schachspiels
''Handbuch des Schachspiels'' (''Handbook of Chess'', often simply called the ''Handbuch'') is a chess book, first published in 1843 by Tassilo von Heydebrand und der Lasa. It was a comprehensive reference book on the game, and one of the most important references on opening theory for many decades. The ''Handbuch'' had been the project of Paul Rudolf von Bilguer, who was with von der Lasa a member of the Berlin Chess Club and the influential group of chess master A chess title is a title regulated by a chess governing body and bestowed upon players based on their performance and rank. Such titles are usually granted for life. The international chess governing body FIDE grants several titles, the most pres ...s later called the Berlin Pleiades. Bilguer died in 1840, with the work still in the early stages. Von der Lasa completed the project and saw it published, with his friend von Bilguer alone named as author.

Rook And Pawn Versus Rook Endgame
The rook and pawn versus rook endgame is a fundamentally important, widely studied chess endgame. Precise play is usually required in these positions. With optimal play, some complicated wins require sixty moves to either checkmate, capture the defending rook, or successfully promote the pawn. In some cases, thirty-five moves are required to advance the pawn once. The play of this type of ending revolves around whether or not the pawn can be promoted, or if the defending rook must be sacrificed to prevent promotion. If the pawn promotes, that side will have an overwhelming advantage. If the pawn is about to promote, the defending side may give up their rook for the pawn, resulting in an easily won endgame for the superior side (a basic checkmate). In a few cases, the superior side gives up their rook in order to promote the pawn, resulting in a winning queen versus rook position (see ). A rule of thumb (with exceptions) is: . The side with the pawn can cut off the opposing k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chess Endgame
The endgame (or ending) is the final stage of a chess game which occurs after the middlegame. It begins when few pieces are left on the board. The line between the middlegame and the endgame is often not clear, and may occur gradually or with a quick exchange 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 attempts to promote a pawn by advancing it to the eighth . The king, which normally is kept safe during the game, becomes active in the endgame, as it can help escort pawns to promotion, attack enemy pawns, protect other pieces, and restrict the movement of the enemy king. Not all chess games reach an endgame; some of them end earlier. All chess positions with up to seven pieces on the board have been solved by endgame tablebases, so the outcome (win, loss, or draw) of best play by bot ...

Resign (chess)
The rules of chess (also known as the laws of chess) govern the play of the game of chess. Chess is a two-player abstract strategy board game. Each player controls sixteen pieces of six types on a chessboard. Each type of piece moves in a distinct way. The object of the game is to checkmate the opponent's king; checkmate occurs when a king is threatened with capture and has no escape. A game can end in various ways besides checkmate: a player can resign, and there are several ways a game can end in a draw. While the exact origins of chess are unclear, modern rules first took form during the Middle Ages. The rules continued to be slightly modified until the early 19th century, when they reached essentially their current form. The rules also varied somewhat from region to region. Today, the standard rules are set by FIDE (Fédération Internationale des Échecs), the international governing body for chess. Slight modifications are made by some national organizations for their ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pawnless Chess Endgame
A pawnless chess endgame is a chess endgame in which only a few chess piece, pieces remain, and no pawn (chess), pawns. The basic checkmates are types of pawnless endgames. Endgames without pawns do not occur very often in practice except for the basic checkmates of king (chess), king and queen (chess), queen versus king, king and rook (chess), rook versus king, and queen versus rook. Other cases that occur occasionally are (1) a rook and versus a rook and (2) a rook versus a minor piece, especially if the minor piece is a bishop (chess), bishop. The study of some pawnless endgames goes back centuries by players such as François-André Danican Philidor (1726–1795) and Domenico Lorenzo Ponziani (1719–1796). On the other hand, many of the details and recent results are due to the construction of endgame tablebases. Grandmaster (chess), Grandmaster John Nunn wrote a book (''Secrets of Pawnless Endings'') summarizing the research of endgame tablebases for several types of pawnless ...

Queen (chess)
The queen (♕, ♛) is the most powerful piece in the game of chess. It can move any number of squares vertically, horizontally or , combining the powers of the rook and bishop. Each player starts the game with one queen, placed in the middle of the first next to the king. Because the queen is the strongest piece, a pawn is promoted to a queen in the vast majority of cases; if a pawn is promoted to a piece other than a queen, it is an underpromotion. The predecessor to the queen is the '' ferz'', a weak piece only able to move or capture one step diagonally, originating from the Persian game of shatranj. The queen acquired its modern move in Spain in the 15th century. Placement and movement The white queen starts on d1, while the black queen starts on d8. With the chessboard oriented correctly, the white queen starts on a white square and the black queen starts on a black square—thus the mnemonics "queen gets her color", "queen on er wncolor", or "the dress uee ...

In the late 1920s, Nimzowitsch was one of the best chess players in the world. He was the foremost figure amongst the hypermoderns and wrote a very influential book on chess theory: '' My System'' (1925–1927). Nimzowitsch's seminal work ''Chess Praxis'', originally published in German in 1929, was purchased by a pre-teen and future World Champion Tigran Petrosian and was to have a great influence on his development as a chess player. Life Born in Riga, then part of the Russian Empire, the Jewish Yiddish-speaking Nimzowitsch came from a wealthy family, where he learned chess from his father Shaya Abramovich Nimzowitsch (1860, Pinsk – 1918), who was a timber merchant.
