I have recently bought the book "The King", a collection of columns
written by late GM J.H. Donner and recently translated into English by
"New In Chess". It is a very interesting reading.

On page 33 of this edition, there is the Sep 6, 1958 column from
Elseviers Weekblad, where the following statement about Bobby Fischer
appears: "During games, he makes a habit of playing a piece and then,
when his opponents sits up, taking the move back. An instant later, he
makes the move after all."

I have never heard of such a behaviour by Fischer before. Does anybody
know more?

Another question raises when, first in a column from "Elseviers
Weekblad" August 22, 1964, then in another one from "De Tijd" January
7, 1965 , there are two different references (both on page 54 of the
aforementioned english edition) to a "no draw within thirtieth-move"
rule abolished at the FIDE congress in Tel Aviv (presumably at the
1964 Olympiad), a rule promulgated two years earlier.

Again, I have never heard of this two-year-long no-draw rule
enforcement before. Was it really so?
