Carlsen wouldn't be nearly 2900 in the 19th century.
He is closing in on 2900 buddy. Already 2882 since his last tournament.
I guess the idea here is to use the DeLorean to kidnap baby Carlsen and find a 19th century home for him. Do we have much data on the result of that sort of experiment?
Is there a reason to believe that CAPS can predict what Morphy could gain from 21st century chess knowledge after climbing out of the DeLorean?
