way too many possibilities
im going to assume u mean chess.com since here and lichess are pretty different and u posted the question here
for how high the rating would climb that totally depends on how much said person wants to climb and if theyre allowed to
for example any top player around supercoolguys skill level could have reached 3000 if they really wanted to and didnt have any restricting circumstances
someone with the restricting circumstances is tla since they could totally do it if they could but are in a ban loop so they get banned before theyre able to
honestly i think most ppl would get bored before reaching 3000 so i say climb max would be 2800-3100 but yea like i said it depends on the person since if they felt like it they would totally be able to overshoot or not reach the expectation at all
for public reactions i think ppl wouldnt want to play them ever unless its someone that looks up to them and wants to try beating them
having a player like this would probably ruin the game
the newer generations would watch that player and copy them and nf3 e3 will eventually become one of the only openings ever played
top players would get annoyed and leave if literally everyones playing nf3 e3 (its already starting to be a problem here)
it just wouldnt be as fun if they influenced everyone to do it
the only ways i can think of to stop nf3 e3 spreading if that player did exist is to either encourage players to not play nf3 e3, somehow not let the players watch their games which is pretty much impossible or somehow get them to discourage others from playing it but that wouldnt make sense since if they play it then they must think the opening is good right??
but yea i dont think a person like this existing would be good for the atomic community
Over the past few weeks, I've been taking a deep dive into Nf3 e3, and as I keep researching, the more I find how relatively "easy" it is to win by force as white by simply knowing a few lines from the opening.
What I hope to bring to the post is a thought experiment. If there existed such a player that was able to win 100% of his games in Atomic as white by exclusively playing Nf3 e3, while still maintaining excellent knowledge of black, how far would you think their rating would climb or what would public reactions be to the player?
