2021 World Cup [Name] Mismatches

In the previous post, 2021 World Cup Tiebreak (August 2021), I documented the first step in converting a TWIC PGN file for a World Cup to a page like 2021 World Cup, Sochi (Russia):-

TWIC delivers the files sorted by game and round : all of the PGN game scores for the first game of the first round, followed by all of the PGNs for the second game, etc. I prefer to have all of the games for each mini-match together.

The second step is to create a text file using my standard structure for a World Cup page. I've been using the same structure since the first FIDE knockout tournament, 1997 FIDE Knockout Matches, Groningen (Netherlands). It's not elegant, but it serves my purpose well enough. While I'm creating the text file, I also compare my results against the official site.

The third and last step is to convert the text file to web page format by adding HTML markup tags. I wasn't able to do this for the current post, because I ran into a number of mismatches that had to be resolved.

One mismatch was an error I made in that 'Tiebreak' post. The other mismatches had to do with the spelling of player's names on TWIC and on the official site. Although I resolved the name mismatches, I ran out of time to go further. I'll document the mismatches at the appropriate place.

Later: After I wrote this post, I realized that the title '2021 World Cup Mismatches' might easily be misunderstood to mean mismatches in playing strength. While there were certainly plenty of those in the event, I corrected the title to describe the content of the post more accurately.

2021 World Cup Tiebreak

In last week's post, A New Cycle Is Evolving (August 2021), I wrote,

Two World Cups finished this past week, so I used the TWIC files to prepare the PGN files for both events.

That was just the initial preparation. TWIC delivers the files sorted by game and round : all of the PGN game scores for the first game of the first round, followed by all of the PGNs for the second game, etc. I prefer to have all of the games for each mini-match together, e.g. for the second round of the unrestricted World Cup (open to both men and women), I prefer to see both games of the Carlsen - Martinovic match, followed by both games of the Caruana - Megaranto match, and so on (using the top two boards in the second round as an example).

That sort takes some effort, but I like being able to get a bird's eye view of each match without any additional work. Since that's not much info for this current post, I'll add a count of the games played in each round of the unrestricted event.

For example, there were 144 players competing in the first round -- 72 mini-matches total for the first and second games of the round -- of which 19 matches went into tiebreak. One of those matches reached the third tiebreak.

The 72 winners of the first round joined 56 seeded players to contest 64 mini-matches in the second round. One of those matches reached the 'Armageddon' tiebreak.

For an explanation of a similar chart and the tiebreaks used in a previous World Cup, see 2015 World Cup Tiebreak (October 2015), on my main blog. NB: I haven't compared the details for the tiebreaks used in the 2015 World Cup with those of the 2021 event, but I suppose they were similar. For the details of the recent event, see 2021 World Cup, Sochi (Russia).

Later: In the next post for this series, 2021 World Cup [Name] Mismatches (August 2021), I wrote,

I ran into a number of mismatches that had to be resolved. One mismatch was an error I made in that 'Tiebreak' post.

That error stems from the sentence above that says,

The 72 winners of the first round joined 56 seeded players to contest 64 mini-matches in the second round.

That statement doesn't square with the official rules, copied on my page about the Sochi event, that said,

Round 1: 156 players
Round 2 (78 winners of Round 1 + 50 top seeds): 128 players

The difference of six players (78 winners - 72 winners) stems from six first round matches that were not played. The players who forfeited those matches are listed here:-

Atabayev (Erdos)
Fan (Lupulescu)
Rodriguez (Ivanisevic)
Wynn (Mikhalevski)
Zaibi (Deac)
Ziska (Moradiabadi)

Their opponents, whose names are listed in parentheses, advanced to the second round.

A New Cycle Is Evolving

In my previous post, TWIC Documents Chess History (August 2021), I wrote,

I'm currently waiting for two concurrent World Cups to finish, so I decided to bring my personal copies of TWIC up to date.

The two World Cups finished this past week, so I used the TWIC files to prepare the PGN files for both events, added the headers for the rounds to 2021 World Cup; Sochi (Russia), VII-VIII, 2021, and created 2021 FIDE Women's World Cup [same venue and dates] on the index page for World Chess Championship for Women. I also updated two pages for qualifying events by adding the latest announcements from FIDE:-

• 2021 Grand Swiss; Riga (Latvia), X-XI, 2021
• 2022 Grand Prix; Berlin, II-IV, 2022

The FIDE announcements were all made in the three weeks since I created the pages for the post A New Cycle Is Advancing (July 2021).

TWIC Documents Chess History

Last week's post, Early Women's Grand Prix Events (July 2021), was a placeholder because,

I'm currently waiting for two concurrent World Cups to finish [plus links]

The same is true this week, so I decided to bring my personal copies of TWIC up to date. Along with the games from the World Cups, I'll need TWIC data to document:-

• The current cycle (C30) zonals and other qualifiers; see posts starting C29 Regulations for World Cup Qualifiers (September 2019); and
• GM Carlsen's record since the last World Championship match; see posts starting Carlsen's Events 2017-18 (September 2018).

The two referenced posts document the start of the work I did for the previous cycle.

Early Women's Grand Prix Events

I'm currently waiting for two concurrent World Cups to finish:-

• 2021 World Cup; Sochi (Russia), VII-VIII, 2021, and
• World Chess Championship for Women ['2021 World Cup' currently just a placeholder]

I didn't have a good idea for today's post, so I looked at ideas in my 'Follow-up' category, Showing posts with label zFLUP. Most of the ideas required more time than I have to spend, but I found one that seemed reasonable:-

• 2015-2016 Women's Grand Prix, the Players (December 2016).

At the time of the post I wrote, 'The first two [WGPs], 2009-2010 & 2011-2012, could use a chart like the one shown.' For each of the players who competed in the Grand Prix, it showed the total score achieved across all events and the number of games played by the player. I added the new charts to the two wrapup pages:-

• [2009-2010 WGP] Names: Certainty and Uncertainty (March 2011)
• 2011-2012 Women's Grand Prix, Players (October 2012)

What's the plural of 'Grand Prix'? I decided to use the phrase shown in the title.

A New Cycle Is Advancing

In the previous post, A New Cycle Is Starting (June 2021), I added the first page for the new World Championship cycle:-

• 2021 World Cup

That tournament is currently underway. For this current post, I added pages for the next two events in the cycle:-

• 2021 Grand Swiss
• 2022 Grand Prix

Those three pages give me anchors for any subsequent announcements from FIDE concerning the new cycle.

A New Cycle Is Starting

The last time I posted about the next FIDE World Championship cycle, A New Cycle Is Coping Nicely (June 2021), I noted an additional twist:-

FIDE's Handbook, D. Regulations for Specific Competitions (handbook.fide.com), includes the usual qualification paths for the 2021 World Cup, and adds a new one:- "VIII. One hundred (100) players are determined according to the Final Ranking of the Chess Olympiad 2020 open section."

The 2021 World Cup starts in a few weeks, so I added basic info about the new cycle to my index page for the World Chess Championship. I also added a new page 2021 World Cup; Sochi (Russia), VII-VIII, 2021. It currently consists mainly of excerpts from the regulations governing the tournament, but much more will be added over the next few months.
