Batsford cover design 2008 edition
Chess historian Edward Winter discovered that there had also been over 570 textual changes. He wrote in CHESS magazine that '... entire notes of Fischer’s had been omitted, individual words had been deleted, other words had been added', and 'Fischer’s wording had simply been changed without justification'.
In 2008, Batsford reissued the book using Fischer's original words claiming that the only change made was the conversion to algebraic notation, although a review found that several typographical errors and notation mistakes have also been corrected.
See Winter's article 'Fischer's Fury' in which he examines the claims.
Below, a fine example of the young Fischer's play against Petrosian, one of the world's toughest GM's at the time and a future World Champion (1963-69). The game is fully annotated in My60MG's.
