If aliens came by and told us the solve, like it's a win for white let's say, wonder how that would affect tournament etiquette. Let's say all they told us was that the perfect game derives out of the Ruy Lopez Opening or something, would people start taking byes instead of playing as black lol?
honestly, even disregarding the whole 'aliens exist!!!' impact, it would be so incredibly humbling to humanity have something that we as a society have all agreed upon be deconstructed by superior knowledge
The idea of aliens landing and telling us all about them already having solved chess - and to make it more plausible that they knew the rules being used here by long distance observation ...
or that they're subterranean aliens ... that fits better.

its a joke but it also could be a different 'framework of discussion'.
