Heh. It's synthesis of various disciplines.
Art + intellect + sport + game + geometry + bla + bla + bla = chess.
Therefore I came with the conclusion = I would define chess as chess. It is art but it is not music, it's not painting nor monumental architectal masterpiece, it is not literar masterpiece, it is not movie, it is not sculpture. It's CHESS !!
Chess, chess, chess, of chess, too much of chess
I can not stand that much of chess anymore, please, a little break. Chess chess chess
