Magnus, next question
Magnus vs Fischer
Magnus. But give Bobby computers, engines, modern books and like 2 years time to prep it could become interesting.

Magnus Carlsen would beat any of the old masters, he does not even need any book to recall there best game positions, he was once showed by G.M Howell 12 famous chess winning positions and gave each position who was white and black, & who Won! Just amazing recall and indication of his amazing abilities!!
Magnus vs Fischer who will win?
