2020 Candidates - Early World Championship Steps

I ended a post last week, Karjakin/Carlsen's Early World Championship Steps, saying,

While we're waiting for the '2020 Candidates Tournament, Yekaterinburg' to resume, I might take the time to determine how all eight of the current candidates first qualified into a World Championship cycle.

To do that, I took the names of the eight players from my page on the 2020 Candidates Tournament, then looked up each name in the Index of Players to find the first World Championship event for that player. The following table summarizes the results of that exercise:-

Alekseenko K	2019 WCup
Caruana F	2009 WCup
Ding Liren	2011 WCup
Giri A	2013 WCup
Grischuk A	2000 KO
Nepomniachtchi I	2011 WCup
Vachier Lagrave M	2009 WCup
Wang Hao	2005 WCup

The 'KO = Knockout' format was the same as the 'WCup = World Cup'. For each of the KO/WCup events, I looked up the qualifying paths ('QP') in the 'Clippings' section at the bottom of the Index of Zonals. The following overview summarizes the result for each of the six unique events listed in the table above.

2000 KO • Zonal Qualifiers 2000-2001 (C19)

2019 WCup • Zonal Qualifiers 2018-2019 (C29)

Alekseenko K [?]

Only for the last event (2019 WCup), did the relevant QP page fail to identify the qualifying path for the player. According to Wikipedia's page on Kirill Alekseenko:-

Although [Alekseenko] failed to qualify for the Chess World Cup 2019 through European Championship placement, he was chosen as a wildcard nominee by the organiser of the tournament.

Indeed, my page 'Zonal Qualifiers 2018-2019' has a number of blanks for the various nominees:-

Nominees of the FIDE President
1. Kovalenko Igor (LAT)
2. Salem A. R. Saleh (UAE)
3. Urkedal Frode Olav Olsen (NOR)
4. Ziska Helgi Dam (FAI)
5.
Nominees of the Organizer
1. Iljiushenok Ilia (RUS)
2. Pridorozhni Aleksei (RUS)
3.
4.

The exercise was useful not only to learn more about the importance of the different qualifying paths, but also to identify some weaknesses in my own pages. • To do: (1) Fill in those three blanks for the nominees to '2019 WCup'. (2) Crosslink (in both directions) the IZ/KO/WCup pages with the corresponding QP page for faster navigation between them.
