In 2008 in Bratislava, the Slovakian master Ivan Novak decided to solve studies by the Czech composer Ladislav Prokes. It was a formidable task because Novak could not use his sight. He is legally blind. When he came across the Prokes/Duras study, he solved it the same way as Noam Elkies did two years later. He didn't consider Prokes's 7.f3 and came up with 7.Qxd3+. To eliminate the Prokes's version, Novak removed the black d-pawn and swang the windmill in two directions.
His idea was published in the Pravda newspaper.
