Queen (chess)

The queen is the most powerful piece in the game of chess.

She serves as a vital tool for both offense and defense. Because of her immense range, she can influence many different areas of the board at once. This power makes her the most valuable piece for a player to protect. In many ways, the queen defines the tempo and the tactical possibilities of a match.

To move the queen, a player chooses any unoccupied square in a straight line. This movement can be vertical, horizontal, or diagonal. By combining these paths, the queen essentially merges the abilities of the rook and the bishop. A rook moves in straight lines, while a bishop moves diagonally. The queen can do both. To capture an enemy piece, the queen simply moves into the square occupied by that piece.

Each player begins with one queen on a specific starting square. The white queen starts on d1, and the black queen starts on d8. A common mnemonic used by players is that the queen "gets her color." This means the white queen begins on a white square, and the black queen begins on a black square.

There are different ways a queen can appear on the board. Each player starts with one queen, but more can be added through promotion. When a pawn reaches the opponent's furthest rank, it can be promoted to another piece. While a player can choose a rook, bishop, or knight, they almost always choose a queen. This process is colloquially known as "queening." Because the queen is so much stronger than other pieces, it is the most common result of promotion. In some historical contexts, a pawn that became a queen was called a ferzia to distinguish it from the original queen.

Historically, the queen has undergone a massive transformation. The piece began as the ferz, or vizier, in the Persian game of shatranj. The ferz was a much weaker piece that could only move one square diagonally. Around 1300, its power increased slightly, allowing it to jump two squares diagonally on its first move. The modern queen, with its current combination of rook and bishop moves, emerged in Spain during the 15th century. This version of the game was sometimes called "madwoman's chess" in Italy. Some historians suggest the queen's sudden rise in power may have been inspired by powerful female leaders like Isabella I of Castile.

In terms of value, the queen is typically worth about nine pawns. This makes her slightly stronger than a rook and a bishop working together. However, she is slightly weaker than two rooks combined. The queen's advantage over a rook and bishop comes from her superior mobility. A queen can transfer her entire power to a new location in a single move. In contrast, moving the combined power of a rook and bishop requires two separate moves. Additionally, the queen can control squares of both colors, whereas a bishop is restricted to just one.

Strategy involving the queen requires great care. Beginners often move the queen too early in an attempt to achieve a quick checkmate, such as the scholar's mate. However, high-level players generally delay developing the queen. Moving her too soon can expose her to attacks, forcing the player to waste time moving her to safety. Despite this, there are established openings, like the Scandinavian Defense, where early queen moves are considered sound. In some rare cases, a player may even perform a queen sacrifice. This is a deliberate move where a player gives up the queen to gain a better tactical position, such as in the famous Anderssen–Kieseritzky game of 1851.

The queen's influence extends into various cultural and linguistic traditions. In many languages, the piece is called a "lady" or "regina." In others, such as Russian, it retains the Persian name "ferz." In Poland, the piece is known as the "hetman," a term for a historical military-political office. The queen's role is central to the endgame, where a queen and king can easily defeat a lone king. Her presence dictates the complexity of the game, connecting individual moves to the broader systems of logic and strategy that define chess.
