"Rubingh cracks a copy of a hardcover Serbian comic book. He runs a finger along a few panels picturing a man with a leg that has been shorn off at the knee, gushing blood. This is where Rubingh got his idea for chessboxing. The comic, "Alexander Nikopol Gesamtausgabe," is part of a trilogy created by Enki Bilal, a Serbian comic book legend. It tells the story of an apocalyptic society of escalated violence, set in the year 2034. In this world, hockey is played with steel, stick blades sharpened into knives. And two men box one another on a chessboard floor, the match ending with one player braining the other with the queen."
That looks like an awesome book though, wish I could find out what it is.
