May I bring to the table what I call 'The Chiral Rook'. The Chiral Rook
is the same as the normal Rook, but it can only access the left or right
side of the board, which determined by its initial placement. This Rook
can access only half of the board, and thus is similar to a Bishop, which
is often called a colourbound Rook. What is the value of such a piece? How
would it change when there is rotational symmetry?
