I think Magnus
I assume you are talking about classical over the board chess. I don't think he will achieve 3000.
He would have to start winning a much bigger percentage of his games to separate himself from his peers.
In the recent world championship, he did not appear to have such an advantage over Fabiano in classical chess.
Don't get me wrong. I like Magnus. The last win in the last world championship against Karjakin was amazing. He may stay champion for another decade for all I know.
But how he finds that extra gear to get to 3000, nobody knows.
