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? Edit Form You may not post a new comment, because ItemID Colourboundness does not match any item.
