The Astrology of Title Fights builds on two prerequisites: The Horary Textbook and Sports Astrology, both by John Frawley. Winkle corrects some of Frawley's concepts about predicting title fights, and he offers new insights and additional rules, especially in regard to the roles of the Sun and Moon. Winkle's text is much more straightforward than the entertaining John Frawley, but he supplies tables of rules and 30 sample charts to guide the reader. He also provides an extra chapter at the end on predicting knockouts.
