The parties may either submit the case or argue it. The party with the burden of the issue shall have the opening and closing arguments. In opening, the party shall disclose all points the party relies on, and if the party's closing argument refers to any new material point or fact not so disclosed, the adverse party may reply thereto, which shall close the argument. A party waiving opening argument is limited, in closing, to reply to the adverse argument; otherwise the adverse party shall have the closing argument. The court may limit the time for argument to itself, but not for arguments to the jury.
