I believe the essence of the argument is this: "Centaur" advocates believe that this type of chess is an art of its own. Which is defensible. "
I believe it is as defensible as claiming paint-by-numbers is equally valid an art form as is Romantic era painting and should have its own place in the same art museum.
I don't think that is a good analogy.
Then again they hang up all sorts of bullshit in art galleries sometimes. They were actually displaying giant canvases that had nothing but red paint covering the whole square. And they had a whole room of them on the 2nd floor, some blue, some green. I couldn't believe what I saw -- I'm not kidding here. I wish I could have taken a picture of one of them.
