In a blog post Jennifer Shahade, who annotated 15 chess games for the upcoming book Marcel Duchamp: The Art of Chess, argues against the idea that Duchamp "renounced art for chess".  Instead, she says, Duchamp’s chess playing acutally contributed to his art.  He created works inspired by chess, from his early work The Chess Game (1910) The Large Glass (The Bride Stripped Bare by her Bachelors, Even) (1915-1923).   Shahade also argues that chess and art have many factors in common, such as the fact that confidence and focus are key to both.  She concludes that Duchamp’s chess playing was not simply "seless pastime that didn’t inspire him or add anything to his oeuvre", but rather a vital part of his life and art.
