'Fisher was so smart and gifted at chess, he started at a pro level. His mind could work so quickly and efficiently at chess, that once he knew the rules, he could play as well as a pro, much like a computer that plays as well as a pro after the rules are programmed into it. He was probably initially playing at a 1,800-2,000 rating, which is considered a master, and practice got him to 2,500-2,900 very quickly, which is a grandmaster rating.'
This is just nonsense. Fischer started playing when very young and it is highly unlikely he was strong when he started. He studied like crazy before he played games in public.
