I think the real question is, if we could remove Bobby Fischer's brain, teach it nothing but the rules of chess, and have it play itself 44 million times; and if we then did the same with Magnus Carlsen's brain, and then took these two brains in tanks, let's call them Fischer Zero and Carlsen Zero, and have them play each other in a classical tournament, then the question - the real question - not the obvious basic questions like "how stupid is this idea?" or "how much prison time would you get?" - the real question is which one would have sharper barbs, the most vicious invective to throw after the match?
I'm going with little bobby zero.
Well, it's a matter of what "ahead" means. Being the best chess player is not a matter of having the highest CAPS score (whatever obscure calculation that is) or the highest engine match-up. These are surely correlated with chess rating, but correlation does not mean a direct relationship. (Ratings are usually a fair comparison, although it is fair to say players in different eras may not have a level playing field for this either).
