FWFRCC PGN

Last week's post, FWFRCC Game Scores (June 2022), started, 'The year 2019 was the year of the 'FIDE World Fischer Random Chess Championship' (FWFRCC)', then developed a table documenting the tournament's various stages. It finished,
That table should allow me to identify the individual game scores. The games from later stages are more important than those from earlier stages.

The first important stage, 'Qualifying Stage 3: Knockout Qualifier Phase [Q3]', consisted of six knockout (KO) events, each with 16 strong players. Let's look more closely at the first KO event [KO1], which was reported in Nepomniachtchi Qualifies For FIDE World Fischer Random Chess Championship (chess.com; 13 August 2019).

Each of the 15 KO1 matches had at least two games (some had more). Three of those games were embedded in the Chess.com news article. Embedded games have an 'analysis' icon (lower left) that opens an analysis window, which in turn has a 'share' icon (lower right) that displays the PGN, permitting its download. That's fine for embedded games, but what about the other games?

Each player on Chess.com has a profile page. For example, the winner of 'Q3-KO1' has a page titled GM Ian Nepomniachtchi (lachesisQ) - Chess Profile (chess.com). The profile pages lead to a page 'Chess Opening Explorer & Database', initialized for that player. Unfortunately, a help page How do I use the Game Explorer? (support.chess.com), informs,

Currently, the Explorer does not index Live Chess games shorter than 5|0, Chess960 games, or any games of fewer than four moves in length.

Fortunately, the site offers an API which is documented in Published-Data API (chess.com). For GM Nepomniachtchi, all of his Chess.com games are available via lachesisq/games/archives. One of the entries there is lachesisq/games/2019/08, i.e. the month when 'Q3-KO1' was played. The FWFRCC chess960 games are mixed in with other games that Nepomniachtchi played that month, but these could be separated.

We seem to have all the pieces to build a database of 2019 FWFRCC PGN game scores. It would be a non-trivial job to gather all of the games, but it should be possible.

FWFRCC Game Scores

The year 2019 was the year of the 'FIDE World Fischer Random Chess Championship' (FWFRCC). After posting a dozen times on the event, I summarized them in FWFRCC Wrapup (December 2019). The summary post finished with a question:-
2019-11-23: 2019 FWFRCC Final Live • 'First question: where are the game scores?'

Where indeed? I returned to that question attempting to locate as many game scores as possible. The first step was to identify the many smaller events that went into the FWFRCC. While the info probably exists in several places, a useful reference is FIDE World Fischer Random Chess Championship Quarterfinals (chess.com; October 2019), which has a detailed explanation of all stages/phases. Following is a summary of their titles plus a code in brackets ('[]') for easy reference:-

Online Qualifying; Location: Chess.com
Qualifying Stage 1: Non-Titled Open Qualifying Phase [Q1]
Qualifying Stage 2: Titled Play-In Qualifier Phase [Q2]
Qualifying Stage 3: Knockout Qualifier Phase [Q3]

Live Quarterfinals, Semifinals & Finals; Location: Baerum, Norway
1. Quarterfinals Stage 1 [L-QF]
2. Quarterfinals Stage 2 [-"-]
3. Semifinals [L-SF]
4. Finals and Third Place Match [L-FI]

The following table cross references my blog posts with the stages/phases listed above. It includes only the last post for a particular phase, which might not have been mentioned in the title of the post. For example, the 'So Beats Carlsen' post includes a writeup of the semifinals, with relevant links to Chess.com. A couple of Chess.com pages are also mentioned in the table, because they include links to the many individual events that made up the stage.

That table should allow me to identify the individual game scores. The games from later stages are more important than those from earlier stages.
