Hallo,
Fritz Schäfer
Und hier: "Schäfer, himself also a fan of chess, considered this market an opportunity to turn his PET into a chess computer through custom software. Therefore, he, together with a friend who also owned a PET 2001, created the chess game Boss.... Meanwhile, Schäfer was discussing the possible international distribution of the game with British distribution partners, who stated that the name "Boss" was negatively connotated in the English language. Subsequently, Boss was renamed Grandmaster"
Grüß,
Eric
