While I was doing these tasks, I noticed that there were significant differences between the 128 players listed as 'World Cup Qualifiers' and the 128 players who actually participated in the World Cup. I created the following chart to identify the differences.
2019 World Cup, Khanty-Mansiysk
Left: Qualified, but didn't play
Right: Played, but not on list of qualified players
Unfortunately, I didn't have the time to go further with the comparison. If I ever continue with the idea, I might also try to apply it to the players listed on Zonal Qualifiers 2016-2017 (C28). Ditto for previous cycles.
Later: Here are a couple of notes on the chart.
Re zonal 3.6, 'Illingworth Max (AUS)' was replaced by 'Press,S'. See Shaun Press's Chessexpress blog post, Lots of travel for a bit of chess (August 2019) for more info like:-
GM Max Illingworth was the original representative from the Oceania Zone, by virtue of winning the 2019 Oceania Zonal. However, due to personal circumstances he was unable to attend the World Cup, which meant the runner up could go in his place. I was the runner up!
The blog also has followup reports posted during the World Cup, like White in the first game (September 2019). Earlier reports from the zonal tournament, like 2019 Oceania Zonal (February 2019), were also posted on the blog.
Re 'Nominees of the FIDE President', the qualification of 'Salem A. R. Saleh (UAE)' prompted me to include '3.1e Dubai (UAE) 2018-11' in the list of zonals. Since the player wasn't replaced by another competitor in the tournament, this might have been unjustified speculation on my part. To be confirmed.
Even later: From an announcement on Fide.com, Players qualified for the World Cup 2019 - Average ELO & ACP Tour (July 2019), after 18 players qualified by 'Average Rating' there were five players listed as 'Reserve':-
Vidit, Santosh Gujrathi
All of those players participated in the World Cup. Looking at the six players still unaccounted for, two had ratings around 2700, which was the approximate cutoff point for the listed reserves:-
The other four players were relatively young with ratings in the low 2600s ('B-Year' from ratings.fide.com):-
Abdusattorov, Nodirbek [B-Year 2004]
Chigaev, Maksim [B-Year 1996]
Nihal Sarin [B-Year 2004]
Pichot, Alan [B-Year 1998]
I imagine that these players were nominees of the authorized FIDE representatives.
The last word(?): The Wikipedia page for the event, Chess World Cup 2019 (wikipedia.org), has a section titled 'Qualification paths', which ties all of the loose ends together.
|Nihal,Sarin||FIDE President nominee|
One more discrepancy is worth mentioning. The last player on the list, 'Vidit,S', is listed in Wikipedia as 'Vidit Gujrathi'. In the section above, titled 'Even later', he is listed as 'Vidit, Santosh Gujrathi'. On my Index of players (T-Z), he is listed as 'Vidit S' where his first WCC event was the '2015 WCup'.
