I have actually thought of a way to define a variant too large for anyone in this universe to play (whether human, alien monsters, computer programming, or whatever) and therefore is probably impossible to solve by computer too; I have defined a googolplex kind of pieces but had some trouble to define the primitives it is made from in order to ensure all of them are different (however, I think I may have figured out the solution just now).

Perhaps that isn't what you want though. Well, the answer to your question still isn't clear. Even in games where "there aren't so many moves which are at all sound", it seems to me that you should need a mathematical proof of that statement in order to correctly take advantage of it. (Still, it may be possible to make such a mathematical proof without enumerating all of the moves; it is possible to prove a lot of things about numbers which are larger than the universe.)

Quick Markdown Guide

By default, new comments may be entered as Markdown, simple markup syntax designed to be readable and not look like markup. Comments stored as Markdown will be converted to HTML by Parsedown before displaying them. This follows the Github Flavored Markdown Spec with support for Markdown Extra. For a good overview of Markdown in general, check out the Markdown Guide. Here is a quick comparison of some commonly used Markdown with the rendered result:

Top level header: <H1>

Block quote

Second paragraph in block quote

First Paragraph of response. Italics, bold, and bold italics.

Second Paragraph after blank line. Here is some HTML code mixed in with the Markdown, and here is the same <U>HTML code</U> enclosed by backticks.

Secondary Header: <H2>

  • Unordered list item
  • Second unordered list item
  • New unordered list
    • Nested list item

Third Level header <H3>

  1. An ordered list item.
  2. A second ordered list item with the same number.
  3. A third ordered list item.
Here is some preformatted text.
  This line begins with some indentation.
    This begins with even more indentation.
And this line has no indentation.
