Editing Queen (chess) (section)

==Piece value==
{{Further|Chess piece relative value}}
The queen is typically worth about nine pawns, which is slightly stronger than a rook and a bishop together, but slightly weaker than two rooks, though there are exceptions. It is almost always disadvantageous to [[Exchange (chess)|exchange]] the queen for a single piece other than the enemy's queen.

The reason that the queen is stronger than a combination of a rook and bishop, even though they control the same number of squares, is twofold. First, the queen is more mobile than the rook and the 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, the bishop always being restricted to squares of one color. Second, unlike the bishop, the queen is not hampered by an inability to control squares of the opposite color to the square on which it stands. A factor in favor of the rook and bishop together is that they can attack (or defend) a square twice, whereas a queen can do so only once. However, experience has shown that this factor is usually less significant than the points favoring the queen.<ref>{{Citation |last=Larsen |first=Bent |title=Lærebok i sjakk |year=1975}}</ref>

The queen is strongest when the board is {{chessgloss|open game|open}}, the enemy king is poorly defended, or there are ''loose'' (i.e. undefended) pieces in the enemy camp. Because of its long range and ability to move in multiple directions, the queen is well-equipped to execute [[Fork (chess)|forks]]. Compared to other long range pieces (i.e. rooks and bishops), the queen is less restricted and stronger in {{chessgloss|closed game|closed}} positions.
