I wonder if Poul Morphy would have been better with the all the knowledge we have or about chess today or if that would have ruined his creativity.
Poul Morphy must have learned most of the theory on his own.
I guess based on the knowledge we have today Carlsen would beat Morphy blindfolded.
however if we upgrade Poul Morphy with todays theory I guess he would be about the same strength
I don't know how you suppose you even possibly determine this.
