Sicilian, Dragon, Yugoslav Attack, 12.h4
In chess, the move 9.Bc4 is one of the main options in the chess opening called the Yugoslav Attack, which is an attack in the Dragon Variation of the Sicilian Defence. Also known as the Rauzer System or the St George Attack, the Yugoslav Attack begins with the following moves: # e4 c5 # Nf3 d6 # d4 cxd4 # Nxd4 Nf6 # Nc3 g6 # Be3 Bg7 # f3 0-0 # Qd2 Nc6 # Bc4 English GM John Emms states: I can safely say that the Yugoslav Attack is the ultimate test of the Dragon. White quickly develops his and castles long before turning his attentions to an all-out assault on the black king. To the untrained eye, this attack can look both awesome and unnerving. Statistically, Chessgames.com's database of nearly 1500 master games shows win–draw–loss percentages for White to be: 46%–25%–29%. Mega Database 2002 indicates that White scores 52% while 66% of the over 1200 games were decisive. The '' ECO'' code for the Sicilian Dragon, Yugoslav Attack, 9.Bc4 is B77. Ove ...

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 ...

World Chess Championship 1975
The 1975 World Chess Championship was not played due to a dispute over the match format. Champion Bobby Fischer (United States) was to play Anatoly Karpov (Soviet Union) in Manila, commencing June 1, 1975. Fischer refused to play the then-standard "Best of 24 games" match and, after FIDE was unable to work out a compromise, forfeited his title instead. Karpov was named World Champion by default on April 3, 1975. 1973 Interzonal tournaments Two 18-player, single round robin Interzonals were played with the top three from each qualifying for the Candidates Tournament.

Half-open File
In chess, a half-open file (or semi-open file) is a with pawns of only one color. The half-open file can provide a line of attack for a player's rook or queen. A half-open file is generally exploited by the player with no pawns on it. Many openings, such as the Sicilian Defense, aim to complicate the position. In the main line Sicilian, 1.e4 c5 2.Nf3 d6 (or 2...e6, or 2...Nc6) 3.d4 cxd4 4.Nxd4, White obtains a half-open d-file, but Black can pressure White along the half-open c-file. In positions where White has no pawns on a file but Black has one pawn or more on that file, the position is considered to be half-opened for white. During instances where Black has zero pawns on a file but White has one or more pawns on that file, the position is considered to be half-opened for black. In such instances where pawns capture or advance, in a way that it opens or half-opens a file or files, this instance is called a pawn break. The demolition of the pawn structure is a common th ...

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 ...

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 ...

The Exchange (chess)
In chess, the exchange is a situation in which one player exchanges a (i.e. a bishop or knight) for a rook. The side which wins the rook is said to have ''won the exchange'', while the other player has ''lost the exchange'', since the rook is usually more valuable. Alternatively, the side having a rook for a minor piece is said to be ''up the exchange'', and the other player is ''down the exchange''. The opposing captures often happen on consecutive moves, although this is not strictly necessary. It is generally detrimental to lose the exchange, although occasionally one may find reason to purposely do so; the result is an ''exchange sacrifice'' (see below). The ''minor exchange'' is an uncommon term for the exchange of a bishop and knight. "The exchange" differs from the more general "exchange" or "an exchange", which refers to the loss and subsequent gain of arbitrary pieces, for example to "exchange queens" would mean that each side's queen is .
