Nabokov spent considerable time during his exile on the composition of chess problems. Such compositions he published in the Russian émigré press, Poems and Problems (18 chess compositions) and Speak, Memory (one problem). He describes the process of composing and constructing in his memoir: "The strain on the mind is formidable; the element of time drops out of one's consciousness..." To him, the "originality, invention, conciseness, harmony, complexity, and splendid insincerity" of creating a chess problem was similar to that in any other art.

Chess will be an art when chessplayers can get government subsidies/funding/tax dollars to "create" games. Sure, there will be beautiful moves and beautiful games but...to be considered art you have to be able to make money
I can hardly wait. I got this high concept piece where I place a 6" Staunton king into a jar of urine.
