How many books did Bobby Fisher read when he was kicking ass at 12 years old?
Only one, Pandolfini's Traps and Zaps.
Lol! I don't know when he studied, but I thought he had access to John Collins' library which was pretty large. There were also all the Russian publications he bought at a Russian bookstore, (Viktor Kamkin maybe?), which I think is part of the reason he was being watched by the FBI.
At 12 years old?
Actually, I don't know precisely when he started to be tracked by the FBI or when he started looking at Russian publications. I would guess that both were later.
Mir Sultan Khan was illiterate, yet he was the British champion at least twice. So, yes, it is possible.
That's what I was going to say. Sultan Khan definitely did not learn from books, and he was much stronger than 2000.
It only takes one example to prove that something isn't impossible, so the case is closed. If people want to change the argument to 'very difficult', then I agree, but there is a world of difference between difficult and impossible.
