A bunch of grandmasters have now talked about the psychological aspect of even just wondering if your opponent could possibly by cheating, and second guessing if a bad looking move by your opponent might actually be a brilliant engine line.

It seems that might even be enough for Hans as a 2675 rated player to get an edge against 2800+ player without even actually cheating

That doesn't scale down the skill level. At top level of just about any thing the difference between player is decided by few mistakes (by that I define less than optimal action).

If average player does 100 mistakes per match fixing 4 of them won't matter. But if great player makes 6, fixing even single one can be deciding

Hot take, but chess is a zombie sport.

Software running in a smartphone can play deep games against each other.

Chess engines aren't like car engines are to sprinting. They are more akin to text-to-image AIs but as though every single picture they produce is better than what any artist ever could produce.

Part of that is because Chess is easily defined (the win conditions are comparatively simple).

I'm rambling now and I think that's enough wall of text for a hot take.
