Yochanan Afek present his study which was introduced for solving in the 50th birthday party of Karel van Delft in Apeldoorn 2006 and was dedicated to him as a jubilee gift. It was published online in the SBSA messages (a newsletter of Apeldoorn chess that ceased to appear ever since) in 2006.

Take a look that the Zabunov theme occurs after playing of the white Bishop g8 on d5 (the Bishop is front piece of the first thematic battery B-R and become a rear piece of the second battery P-B) . You can see my article "The Zabunov theme in Selfmates" on the following link:
