A queen has about the same value as two rooks. This means that in terms of strategic importance and power on the chessboard, a queen is considered to be roughly equivalent to two rooks. This is because the queen has the ability to move in any direction, both horizontally and vertically, as well as diagonally, giving it a wide range of movement and attacking potential. The two rooks, on the other hand, can only move horizontally and vertically, but they can work together to control more squares on the board. Therefore, the value of a queen is often compared to that of two rooks.
