Debut monograph of candidate for master of sports Blagut Roman and FIDE master Kostak Tatyana, coaches of the Gambit chess club (Kyiv), is devoted to the study of the white spot on the map of chess openings. The authors chose as an object for their research a little-studied central countergambit, which in English-language publications is called "The Elephant Gambit." The gambit is an elephant, not a chess piece of the same name. In the post-Soviet space, this is the first publication on such a topic.
