The Queen can't make any captures here as the no black piece is in the way of all the possible directions the queen can travel to.
The Queen:
The queen is the most powerful piece. Shemoves in any one straight direction - forward, backward, sideways, or diagonally - as far as possible. Queen's cant jump over her own pieces and share a square with another piece of her own colour. And, like with all pieces, if the queen captures an opponent's piece her move is over. Remember, Queen's capture the same direction the move toward, and once they make a capture, they stop at that square. The Value of a Queen is equal to 9 points. Refer to the diagram on the left to understand the movement of a Queen.
