This article uses algebraic notation to describe chess moves.

The queen (♕,♛) is the most powerful piece in the game of chess. Each player starts the game with one queen, placed in the middle of their first rank next to their king. The white queen starts on a white square, and the black queen on a black square, thus the mnemonic "queen gets her color" or "queen on color". In algebraic notation, the white queen starts on the d1 square and the black queen starts on the d8 square.

In the game shatranj, an ancestor of chess, the queen was a fairly weak piece called a fers or vizier, only able to move or capture one square in a diagonal direction similar to a pawn. The modern queen's move arose in 15th century Europe.

The piece is archaically known as the minister. In Polish it is known as the Hetman – the name of a major historical military-political office. In Russian it keeps its Persian name of ferz (koroleva or Queen is colloquial and is never used by professional chess players).

[edit] Movement

Chess pieces
	King
	Queen
	Rook
	Bishop
	Knight
	Pawn

The queen can be moved any number of unoccupied squares in a straight line vertically, horizontally, or diagonally, thus combining the moves of the rook and bishop. The queen captures by occupying the square on which an enemy piece sits.

Although both players start with one queen each, a player can promote a pawn to any of several types of pieces including a queen when the pawn is moved to the player's furthest rank, which is the opponents first rank. Such a queen created by promotion can be an additional queen or, if the player's queen has been captured, a replacement queen. Such pawn promotion to a queen can be colloquially called queening, which is by far the most common type of piece a pawn is promoted to because of the power of a queen.

[edit] General remarks

[edit] Piece value

Ordinarily the queen is slightly more powerful than a rook and a bishop together, while slightly less powerful than two rooks. It is almost always disadvantageous to exchange the queen for a piece other than the enemy's queen. (see chess piece relative value)

The reason the queen is more powerful than a rook and bishop, even though they control the same number of squares is twofold. First, the queen is a more mobile unit than the rook and bishop, as the entire power of the queen can be transferred to another location in one move while transferring the entire firepower of a rook and bishop requires two moves. Second, the queen is not hampered by the bishop's inability to control squares of the opposite color to the square on which it stands on. A factor in favor of the rook and bishop is that they can attack (or defend) a square twice, while a queen can only do so once, but experience has shown that this factor is usually less significant than the points which favor the queen.^[1]

The queen is at her most powerful when the board is open, when the enemy king is not well-defended, or when there are loose (i.e. undefended) pieces in the enemy camp. Because of her long range and ability to move in more than one direction, the queen is well-equipped to execute forks. Compared to other long range pieces (i.e. rooks and bishops) the queen is less restricted and more powerful also in closed positions.

Beginners often develop the queen as soon as possible, in the hopes of plundering the enemy position and possibly even delivering an early checkmate such as Scholar's mate. This strategy is disadvantageous against experienced players. With no other pieces developed, an attack by the queen alone can be easily repelled. Moreover, because the queen is too valuable to exchange for a lesser piece, the defender can often gain time and space by threatening an exposed queen and forcing her to retreat. Nonetheless, the Scandinavian Defense, which in the main line features queen moves by Black on the second and third moves, is considered sound and has been played at world championship level. Even the Parham Attack (1.e4 e5 2.Qh5!?), which is widely considered a chess opening suitable only for beginners, has occasionally been played by the strong American grandmaster Hikaru Nakamura.

An exchange of queens often marks the beginning of the endgame, although there is such a thing as a queen endgame. Due to the multiplicity of queen moves available, and the possibility of perpetual check, queen endgames are notoriously difficult to win. Endgames often hinge on attempts to promote a pawn to a queen.

[edit] Queen sacrifice

A Queen sacrifice is when the queen - the most powerful piece, is deliberately sacrificed.

[edit] History

The queen was originally the fers (counsellor or prime minister) and had a quite different movement. In Persia it was called the ferzin and later the firz. Initially it could move only one square diagonally. About 1300 its move was enhanced to allow it to jump two squares diagonally, which was the same move as the bishop at the time. For a while it was also allowed to jump like a knight once in the game, somewhat analogous to castling for the king. This rule was used in Turkey and Russia until the 18th Century. During the 15th Century the move took its modern form as a combination of the move of the rook and the current move of the bishop (Davidson 1981:13-14,28-30).
