FM Vladimir Zabunov
zabunovHere are the biography and selected compositions (twomover, threemovers, selfmates, helpmate and fairy) of the famous bulgarian chess composer from the recent past FM Vladimir Zabunov (1928-1997).
   Vladimir Zabunov was born on 24.08.1928 in the town of Shumen (Bulgaria), but lives and works in Varna. He published his first chess problem in 1955. During his long activity he has composed about 400 problems from almost all genres (without studies). Almost half of them were awarded - 79 Prizes (including 16 First), 44 Honourable mentions and 40 commendations.
   His friendship with Dimitar Manev and then with the most successfull bulgarian chess composer GM Petko Petkov has a significant role for his style and growth as a composer.
   Zabunov is awarded the title National Master of Sport in 1971. In 1987 he was approved as an International Judge for Chess Composition (for twomovers and threemovers sections). He won the 1st Place in Selfmate section of the first World Chess Composition Tournament 1976 and later was awarded by the Central Council of the Bulgarian Union for Physical Culture and Sports with the medal "For glories" about that. Zabunov has 12.5 FIDE Album points and he is awarded the title of FIDE Master for Chess Composition in 1990 and thus became only the fourth bulgarian composer with an international title in the history.
   The Zabunov name is associated with the eponymous theme which is defined and gained popularity after he realized it in his Probleemblad 1964 3rd Prize problem. The definition of the theme is: "the front piece from one battery makes an ambush move and becomes the rear piece of a newly created battery." Later the Zabunov theme was chosen for a theme in the second World Chess Composition Tournament.
   The great Bulgarian composer died in 1997.

Excellent problems. He was the master of selfmates but was at home in all types.
