The Queen is the most powerful piece on the board. This is because it can control more squares than any other chessman. It moves straight forward or backwards and diagonally any number of squares. In the diagram the Queen can move to any of the highlighted squares.
However, like all of the other pieces mentioned so far, the Queen's path can be blocked by other pieces.
In the diagram below, the Queen may take either the Bishop or the Rook.
The Queen chooses to capture the Rook!
