As a teenager during the late 70s, Kai Himstedt already developed a chess program along with [[Wolfgang Stahn]] and participated at [https://en.wikipedia.org/wiki/Jugend_forscht Jugend forscht], a German youth science competition, initiated in 1965 by [https://en.wikipedia.org/wiki/Henri_Nannen Henri Nannen], then editor-in-chief of the [https://en.wikipedia.org/wiki/Stern_%28magazine%29 Stern magazine]. In 1980, they won the second prize in the mathematics and computer science section <ref>[httphttps://www.jugend-forscht.de/projektdatenbank/die-entwicklung-eines-schachprogramms-als-beispiel-fuer-eine-spezielle-form-der-kuenstlichen-intelligenz/2.html Jugend forscht 1980 | Mathematik/Informatik | Die Entwicklung eines Schachprogramms als Beispiel für eine spezielle Form der künstlichen Intelligenz] (German), translated with the help of [https://en.wikipedia.org/wiki/Google_Translate Google Translate]</ref>:
Inspired by the chess computer boom and not impressed by the programs offered at the time, the two young friends developed their own computer chess program. As a comparison, the modern American chess program [[Chess (Program)|Chess 4.8]] was available, in which the two young mathematicians discovered certain weaknesses.
