Zonal Qualifiers C15-C26 : Crosslinks

Returning to the table in Zonal Qualifiers C15-C26 : Summary, I linked all of the pages in the 'Zonals' column (aka clippings) to the corresponding page in the 'Qualifiers' column. I also linked each 'Qualifiers' page backed to the 'Zonals' page. As for individual pages, here are discrepancies I flagged in the blog post for each cycle.
  • C15: Zones 4 & 8
  • C16: Qualified by rating?
  • C17: Why Gelfand over Salov?
  • C18-C21: Incomplete data
  • C22-C24: Ditto
  • C25-C26: OK!

Before I tackle those points, I want to address a few more current aspects of the World Championship.

Zonal Qualifiers C15-C26 : Summary

Nearly five months ago, in my first post to document Interzonal++ qualifying paths, Zonal Qualifiers C25-C26, I wrote,
I'll continue backwards in time to see how this works for previous cycles. The new pages aren't yet linked from any other page. That will happen when I'm happy with the structure.

I've taken the project back to C15 and the following table shows the accumulated effort. For each of the twelve cycles, the columns link to the original page documenting the zonal events for the cycle ('Zonals'), the blog post where I released the results for one or more cycles ('Blog'), and the new page listing the qualifying paths for that cycle ('Qualifiers').

Cycle Zonals Blog Qualifiers
C15 1990-93 C15 1990-93Q
C16 1993-96 C16 1993-96Q
C17 1995-97 C17 1995-97Q
C18 1998-99 C18-C21 1998-99Q
C19 2000-01 -"- 2000-01Q

C25 2010-11 C25-C26 2010-11Q
C26 2012-13 -"- 2012-13Q

The next step will be to add crosslinks to the pages in m-w.com. Many of the links in the 'Blog' column flag follow-up actions that need to be addressed separately.

Zonal Qualifiers C15 - Qualification Paths

After completing the preliminary work described in my previous post, Regulations for Qualifiers C15, I tried to determine the qualification paths for each of the 64 players who competed in the 1990 Manila Interzonal. The two tables below show the counts of players who qualified by the different paths.

The left table ('Qual') counts the types of qualifiers as defined in the first part of Zonal Qualifiers 1990-1993 (C15). The right table ('Zonal') counts the players who qualified at a certain zonal ('z'), as listed in the second part of the same page.

At the same time I worked on the qualification paths, I added a few new clippings to Zonals 1990-1993 (C15). These are mainly explanations about players from specific zonals and I have a few more to add when I find the time.

The first row in the 'Qual' table counts eight players where I am not certain how they qualified. These are mainly players who were nominated by Continental Vice-Presidents (Qual = 'd').

Some of the counts in the 'Zonal' table are also likely to be wrong. Zone 4 (USSR) reportedly had six qualifiers from the zonal, but I can only identify five. Zone 8 (Central America) shows three qualifiers, but one of these might have been the nomination of the Continental Vice-President.

Whatever the real status of my tables and counts, they give a good basis for further investigation. Before I pursue that, I would like to incorporate the dozen new pages showing Qualification Paths into the rest of my material on the zonals.
