filled in the blanks, double-checked some assumptions, corrected a few errors, and added the list 'Player - How qualified' to the 'Zonal Qualifiers' page.
The table on the left is similar to the one shown in Zonal Qualifiers C17 - Qualification Paths. It counts and summarizes the qualification paths of the 74 players who competed in the 1993 Biel FIDE Interzonal.
The letters in the left column correspond to the paragraphs from the first section of the 'Zonal Qualifiers' page ('Comment ils se sont qualifiés' = 'How they qualified'). For example, 'a' counts the players who qualified on rating, 'e' counts players who qualified as ex-World Champions (only Smyslov accepted), and 'z' counts players who qualified via a zonal.
The counts total to 76, so where do the two extra players come from? Europe Echecs listed ten players qualified on rating ('a'), but only eight eventually played (Azmaiparashvili and Christiansen were missing). On top of that, I identified another six players who didn't qualify by any obvious path. Since they all had ratings in the same range, I assumed they also qualified on rating and assigned them code 'a?' to keep them separate.
For my next post, I'll tackle qualification paths for the preceding cycle, Zonals 1990-1993 (C15).
