Chess in Conceptual Art

The upside about a category like Posts with label zFLUP (where FLUP = followup), is that it's always there when I need it. The downside is that, once in a while, I actually have to follow something up. Take the photo in A Lonely Knight (January 2017), for example, where the idea to followup was:-

Maybe it would help if I understood what 'conceptual art' meant.

Wikipedia says, 'not to be confused with concept art', and continues,

Conceptual art, sometimes simply called conceptualism, is art in which the concept(s) or idea(s) involved in the work take precedence over traditional aesthetic and material concerns. • Conceptual art

I think I get it. The idea behind 'Lonely Knight' is romantic loss, which makes the photo conceptual. Wikipedia continues,

History: The French artist Marcel Duchamp paved the way for the conceptualists, providing them with examples of prototypically conceptual works -- the readymades, for instance.

The name Marcel Duchamp is often attached to chess, as in a half-dozen posts on this blog. The most recent was Borrowing Leaves (December 2015; 'Marcel Duchamp and Larry Evans playing chess'). Getting back to 'conceptual art', what differentiates it from 'concept art'? Wikipedia again:-

Concept art is a form of illustration used to convey an idea for use in films, video games, animation, comic books or other media before it is put into the final product. • Concept art

While looking for examples of 'conceptual art', I became convinced that Google was confusing the term with 'concept art'. Wrapping the keyword in quotes ("conceptual") produced a different set of examples. I eventually found an entire category on deviantart.com.

Where have I featured that site before? Oh, yes, in Chess on Your Mind (September 2009), which turns out to be another example of conceptual art.
