@Ultracrepidarian,
Ultra, I am still not quite clear why you don't see things like chess and tetris and most other things art. Look at the root, etymological definitions of the word;
"skill as a result of learning or practice"
"art, skill, craft"
"skill in scholarship and learning"
"human workmanship"
"skill in creative arts" (recorded 1620; esp. of painting, sculpture, etc.)
"produced with conscious artistry"
[definitions taken from Online etymology
Online Etymology Dictionary ]
Isn't chess a skill which is the result of learning and patience? Isn't the way we play chess an art, skill, and a craft. But isn't it also the case that the chess board is a medium for that? All the definition above are applicable to the case here.
Chess is not only the board and the pieces themselves, which can be aestheticly beautiful and subject to either subjective or objective criticism, but the way in which it is played provides meaning to the board, the pieces and the game. The way it is played is just as valuable as the intrinsic pieces. If you were a doctor, you have knowledge of a medical art. If you are a lawyer, you have a knowledge of a legal art. If you go to a college or a university, you have to take part in a
liberal arts program, and learn science, language, arithmetic, etc. Ironically, if intangible things like "professions" and "practices" are regarded as art, things like videogames seem like a no brainer. They are the product of that art.
You said it yourself that, "Many chess players will say that chess is art.
It is not. I understand them to mean that playing chess is spiritually involving and beautiful.
Art is something specific. Art is not a sunset, it is an artist's representation of a sunset
