Stalemate (other)
Stalemate is a situation in chess where the player whose turn it is to move is not in check and has no legal move. Stalemate results in a draw. During the endgame, stalemate is a resource that can enable the player with the inferior position to draw the game rather than lose. In more complex positions, stalemate is much rarer, usually taking the form of a swindle that succeeds only if the superior side is inattentive. Stalemate is also a common theme in endgame studies and other chess problems. The outcome of a stalemate was standardized as a draw in the 19th century . Before this standardization, its treatment varied widely, including being deemed a win for the stalemating player, a half-win for that player, or a loss for that player; not being permitted; and resulting in the stalemated player missing a turn. Stalemate rules vary in variants and other games of the chess family. Etymology and usage The first recorded use of stalemate is from 1765. It is a compounding of Midd ...

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 an unattacked square, interposing a piece between the threatening piece and the king, or capturing the threatening piece. If the player cannot remove the check by any of these options, or if using any of these options would result in the player being in check by another piece, the game ends in checkmate and the player loses. Players cannot make any move that puts their own king in check. Overview A check is the result of a move that places the opposing king under an immediate threat of capture by one (or, in rare cases, 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 ...

Political Deadlock
In politics, gridlock or deadlock or political stalemate is a situation when there is difficulty passing laws that satisfy the needs of the people. A government is gridlocked when the ratio between bills passed and the agenda of the legislature decreases. Gridlock can occur when two legislative houses, or the executive branch and the legislature are controlled by different political parties, or otherwise cannot agree. The word "gridlock" is used here as a metaphor – referring to the traffic standstill which results when congestion causes the flow to freeze up completely. Proportional representation In countries with proportional representation, the formation of coalition governments or consensus governments is common. The veto player theory predicts that multiparty governments are likely to be gridlocked, while other literature shows empirical absence of increased gridlock. Majoritarian representation United States In United States politics, ''gridlock'' frequent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harry Pillsbury
Harry Nelson Pillsbury (December 5, 1872 – June 17, 1906) was a leading American chess player. At the age of 22, he won the Hastings 1895 chess tournament, one of the strongest tournaments of the time, but his illness and early death prevented him from challenging for the World Chess Championship. Biography Early life Pillsbury was born in Somerville, Massachusetts, in 1872 and moved to New York City in 1894, then to Philadelphia in 1898. By 1890, having played chess for only two years, he beat noted expert H. N. Stone. In April 1892, Pillsbury won a match two games to one against World Champion Wilhelm Steinitz, who gave him odds of a pawn. Pillsbury's rise was meteoric, and there was soon no one to challenge him in the New York chess scene. Hastings 1895 The Brooklyn chess club sponsored his journey to Europe to play in the Hastings 1895 chess tournament, in which all the greatest players of the time participated. The 22-year-old Pillsbury became a celebrity in the U ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amos Burn
Amos Burn (31 December 1848 – 25 November 1925) was an English chess player, one of the world's leading players at the end of the 19th century, and a chess writer. Burn was born on New Year's Eve, 1848, in Hull.Richard Forster, ''Amos Burn: A Chess Biography'', McFarland & Company, 2004, p. 17. . As a teenager he moved to Liverpool, becoming apprenticed to a firm of shipowners and merchants. He learned chess only at the relatively late age of 16. He later took chess lessons from future World Champion Wilhelm Steinitz in London, and, like his teacher, became known for his superior defensive ability.Forster 2004, p. 9. Aron Nimzowitsch, in his book ''The Praxis of My System'', named Burn one of the world's six greatest defensive players. Although never a professional chess player, Burn had a long career of playing tournaments and writing. In 1913, Leopold Hoffer, the editor for over 30 years of the chess column in '' The Field'', the leading chess column in Great Britain, die ...

Wrong Rook Pawn
In a chess endgame of a King (chess), king, Bishop (chess), bishop, and Pawn (chess), pawn versus a bare king, or, less commonly, a king, rook (chess), rook, and pawn versus a bishop and king, a wrong rook pawn is a (a pawn on the a- or h-file) whose Promotion (chess), promotion square is the opposite color from the bishop's square color. Since a side's rook pawns promote on opposite-colored squares, and a bishop can only move on one color, one of the pawns may be the "wrong rook pawn". This situation is also known as having the ''wrong-colored bishop'' or ''wrong bishop'' (i.e. the bishop is on the wrong-colored squares in relation to the rook pawn). In many cases, the wrong rook pawn will only draw (chess), draw, when any other pawn would win. This is because the defending side can sometimes get their king to the corner in front of the pawn, after which the attacking side cannot chase the king away to enable promotion. A fairly common defensive tactic is to reach one of these dra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wrong Bishop
In a chess endgame, a wrong bishop is a bishop that would have been better placed on the opposite square color. This most commonly occurs with a bishop and one of its , but it also occurs with a rook versus a bishop, a rook and one rook pawn versus a bishop, and possibly with a rook and one versus a bishop. Rook versus bishop White wins in this position. The defender has the wrong bishop if it is on the same color as the corner where his king is confined. Black's bishop is on the wrong color of square for it to form a fortress in the corner (i.e. with the black king on the h8-square and the bishop on the g8- or h7-square). White wins: :1. Kf5! Kg8 :2. Ra4!! The only way to win. If 2.Kg6? Kf8 and the black king is able to get out of the "dangerous corner" or "wrong corner" and head to a "safe corner" or "right corner" where he can set up the fortress. :2... Be1 :3. Kg6 Kf8 :4.

Queen Versus Pawn Endgame
The chess endgame of a queen versus pawn (with both sides having no other pieces except the kings) is usually an easy win for the side with the queen. However, if the pawn has advanced to its seventh rank it has possibilities of reaching a draw, and there are some drawn positions with the pawn on the sixth rank. This endgame arises most often from a race of pawns to promote. The side with the queen is the ''attacker'' and the side with the pawn the ''defender''. Assume that the attacker has the move. If the pawn is not beyond its sixth rank, the attacker (to move) usually wins easily, but there are a few exceptions. The winning process is to either get the queen on a square in front of the pawn and moving the king over to help win the pawn or to check the defending king until it is forced in front of the pawn and using that tempo to bring the attacking king closer, until it can assist in winning the pawn. After the pawn is won, the attacker has an elementary checkmate. Quee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pin (chess)
In chess, a pin is a tactic in which a defending piece cannot move out of an attacking piece's line of attack without exposing a more valuable defending piece. Moving the attacking piece to effect the pin is called ''pinning''; the defending piece restricted by the pin is described as ''pinned''. Only a piece that can move any number of squares along a horizontal, vertical, or diagonal line (i.e. a bishop, rook, or queen) can pin. Any piece can be pinned except the king. The pin is one of the most powerful chess tactics. The inverse of a pin is a ''skewer'', in which a more valuable piece under direct attack may move to expose a less valuable piece to an attack. Types Absolute pin An ''absolute pin'' is one where the piece shielded by the pinned piece is the king. In this case it is illegal to move the pinned piece out of the line of attack, as that would place one's king in check (see diagram). A piece pinned in this way can still give check or defend another piece fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
