The whist tournament problem has attracted the interests of many design theorists for over a century. To construct Z-cyclic whist tournaments, the concept of Z-cyclic patterned starter whist tournaments was introduced. The research on Z-cyclic patterned starter whist tournaments dates back to 1954. Although considerable progress has been made in the last decade or so, less has been made about the existence of Z-cyclic patterned starter whist tournaments, despite the efforts of many authors. In this paper, we will first provide two new nonexistence results for Z-cyclic patterned starter whist tournaments. Then, we will propose a general recursive construction, i.e., a frame construction, for Z-cyclic patterned starter whist tournaments. As a consequence, we are able to unify many known constructions for Z-cyclic patterned starter whist tournaments. The known existence results of such designs are then extended.
