Rules for the 1973 Interzonals

After posting Qualifiers for the 1973 Interzonals (October 2023) a few weeks ago, I found another source of info even more detailed than the source for that post. The January 1973 issue of Chess Life (p.33-34) had an article titled 'FIDE Congress : The Men's World Championship' by Fred Cramer, Vice President of FIDE. It covered all aspects of the cycle, including the following section headers:-
  • The Cycle Ending at [1972] Reykjavik
  • The New Cycle, First Stage : The 1972 Zonals
  • The 1973 Interzonals - The Euwe Plan
  • The 1973 Interzonals
  • The 1974 Candidate's Matches
  • The 1975 World Championship Match
  • A Championship Match Out of Cycle?

I extracted the two sections covering the 1973 Interzonals and created the following composite image.

(Can be expanded)

I then added the image to my page (C09) Zonals 1972-1975 (m-w.com). The Cramer article presents new details about several aspects of the Interzonals and sometimes contradicts sources that I have previously used. Since Cramer was as close to the original discussions as anyone, his word takes precedence.
