On what do you base the claim that he is "about 2400 Elo"? Is that
his USCF or FIDE rating? Or some web-site's? Nowadays there are many
sites with many different rating systems, not all equally valid.
Unless that's a rating from FIDE or a national federation, and one
based on a statistically significant number of games, I'd be chary of
claiming 2400 strength.
