Question

"Bobby Fischer Teaches Chess" was ghostwritten, but did Fischer read it & give it his approval?

Answer 1

Yes.

Answer 2

Presumably the ghost being GM Larry Evans (who by the way was the first teenage US chess champion--7 years before Fischer annexed the title).

Answer 3

It was not ghostwritten, but Fischer had a partner in writing it. And, yes, he did give his approval, as he did with the other book he wrote (My Sixty Memorable Games)
