There's been a few points voiced in the GB Tennis submission thread, that sound very true to feelings of some people.

A Demo tier would sound best as a tier for
research and development achievements. Right? So, R&D being a direction, a movie aiming there must have 2 critical qualities:
optimality and impressiveness. Right?
Now a question. Is a Fool's Mate in Chess impressive, even if it's optimal? Developing a bot that can TAS something is impressive obviously, or making a research on how to complete some absurdly random game, or whatever. But what about the easiest/fastest way to beat any chess party?
If it doesn't look impressive, it can not be added to such a Demo tier. If we still want it there, we should change the "impressiveness" criterion. Sure, if tricking a simple AI into a Fool's Mate is not impressive, tricking some sophisticated one into it may be, but that would mean we'd need to choose games that fit into Demo tier. Which makes it not too reachable for some board games probably.
Please guys let's think over this paradox carefully.
