TCEC S19 DivP Started; CCC15 in Brackets

Two weeks ago, the title of the post, TCEC S19 Underway; CCC in 'Pre-CCC15' (August 2020), gave the overall status of the two leading engine vs engine tournaments. The following summary gives some of the details.

TCEC: Before the start of Season 19 (S19), the TCEC announced its format; the organizers are following the same format they used in S18. A new engine 'SlowChess' won both QL and L3 by significant margins. The site is now in testing for League 2 (L2). • CCC: The 'AlphaZero Simulation Match' finished with Lc0 beating Stockfish 8, the version used in the 2017 AlphaZero - Stockfish match. After that ended, the CCC started running a series of 'Pre-CCC15' events. The name of the next event will be 'CCC15: Bullet II' and it should start this week.

In the meantime, both tournaments have completed subsequent stages.

TCEC: Losing only L2 one mini-match to 1st placed Igel, SlowChess finished 2nd to qualify for L1. There it finished 3rd, a half point short of qualification into the Premier Division (DivP). Fire and ScorpioNN qualified into DivP, which is just getting started and which will run for almost three weeks. The top two engines will qualify into the final match (aka Superfinal or Sufi).

CCC: In my previous post ('CCC in Pre-CCC15'), I noted,

A preliminary document showing the planning for CCC15 is available, but is too cryptic to understand.

It turns out that CCC15 is a straightforward bracket structure starting with a preliminary round-robin equivalent to 12-game mini-matches. That event determined the starting positions for the brackets. The structure of the first three rounds of CCC15 is shown in the following chart.

Stockfish won the preliminary event ('Round 1') by a significant margin. Since there were 17 engines, the two last-placed engines played a qualification match for the 16th place:-

CCC15.01 has been stopped on account of awfulness, and Defenchess declared the winner [over Winter].

Thus spake the arbiter: 'stopped on account of awfulness'. The 'Round 2' matches are underway and the world waits eagerly for the result of Stockfish vs. Defenchess. Will it be a whitewash?

Top Tweeters

Today being the fifth Sunday of the month, I have an extra day for another post in the endlessly interesting series about The Sociology of Chess (November 2016). This video is from Youtube's Best Of Chess Channel.

The Top Chess Twitter Accounts (2:41) • '[Published on] Jul 16, 2020'

The description of the video is a list:-

The current top 15 Twitter accounts:
#1: advorkovich
#2: Kasparov63
#3: vishy64theking
#4: @Magnus Carlsen
#5: @ChessQueen
[...]

@ChessQueen is the one and only Alexandra Kosteniuk, who led the pack for a long time but has fallen behind during the past few years. For the other ten names, see the original Youtube page (right click the video for the address). This is the third time I've featured a video using this time travel bar chart technique. The first two were:-

• 2020-03-08: Youngest GMs
• 2020-05-21: Breaking the 3100 Barrier

I called it the 'time travel bar chart technique'. I wonder what the real name is. A discussion in the comments went like this:-

Q: 'what is the cause for Dvorkovich losing so many followers over the last couple years?' • A: 'I think that is Twitter cracking down and closing bots, and his account has more bot followers than other accounts.'

Why would Dvorkovich need bot followers? Since he is FIDE President, I would imagine that anyone interested in world chess would be dissecting his every word.

Update on Online Chess Events

At the beginning of the summer, in No Online Chess Yahoos (June 2020), I developed a chart showing online chess events across various online play sites, based on TWIC reports ('The Week in Chess' by Mark Crowther). For easy reference, here is the same chart.

T1331 : 'The Week in Chess 1331, 11th May 2020'

As we reach the end of the summer, I developed a similar chart showing the online events over the last eight weeks.

T1339 : 'The Week in Chess 1339, 6th July 2020'

Activity for the three main sites has declined, reflecting perhaps the gradual lifting of coronavirus lockdowns or perhaps the frustration of interminable cheating scandals. Tournament activity generally increases during the summer months.

Note two changes to the names on the chart: the ICC appears for the first time and Europe-Chess has been corrected to Europe-Echecs; it is a French site, after all. Sacré bleu!

Top News/Tournaments in August

At the end of last month, in a post titled Top Tournaments in July (July 2020), I took a survey of chess news stories reported by Google News and came up empty-handed for anything out of the ordinary. This current month had a number of good stories, all of them related to online chess. Here's the first:-

• 2020-08-04: Agadmator: From smalltown Croatia, an unlikely chess phenomenon (espn.com; Susan Ninan)

I mention the author because we already saw her in Coronavirus Candidates (March 2020), where I noted,

Going back even further in time, most -- if not all -- of the older ESPN chess stories had something to do with India. Take this next one, for example. [2020-01-09: Q&A with Viswanathan Anand; ...] The same Susan Ninan was the writer of the four stories on the Candidates.

Two more Google News stories highlighted two of the most visible (and vocal) players of our time:-

• 2020-08-21: Magnus Carlsen wins richest and most-watched online chess event ever (cnn.com; video) • 'The Norwegian world champion has won the finale of the Magnus Carlsen Chess Tour, the richest and most-watched chess event in history.'
  
  
• 2020-08-27: Esports giant TSM signs Hikaru Nakamura, its first pro chess player (theverge.com) • 'Nakamura is also a popular Twitch streamer'

On the Carlsen story, the headline is more accurate -- 'richest and most-watched *online* chess event ever' -- but I'm not complaining. In 'Top Tournaments in July' I identified the top five events in each weekly edition of Mark Crowther's 'The Week in Chess' (TWIC). Let's do the same for August.

1) Introduction

THE WEEK IN CHESS 1343 - 3rd August 2020
2) Legends of Chess 2020
3) 53rd Biel Chess Festival 2020
4) Polish Chess Championship 2020
5) ACP - Chessbase Knock-Out 2020
6) FIDE Online Olympiad 2020

THE WEEK IN CHESS 1344 - 10th August 2020
2) Legends of Chess 2020
3) Magnus Carlsen Chess Tour Final 2020
4) 7th Prague Summer Open 2020
5) 4th Irena Warakomska Memorial 2020
6) Polish Women's Championship 2020

THE WEEK IN CHESS 1345 - 17th August 2020
2) Magnus Carlsen Chess Tour Final 2020

3) 31st Porto San Giorgio Open 2020
4) BSSZ Aranytiz 2020
5) Plzen Chess Festival 2020
6) ch-ISL 2020

The 'M.C. Chess Tour' received TWIC's top billing for the last two weeks listed above. In his introduction to TWIC 1346, Crowther wrote,

Magnus Carlsen won his tour final against Hikaru Nakamura but it was an extremely close contest settled by an Armageddon tie-break that could have gone either way. Nakamura showed that his online skills are pretty much undimmed and Carlsen clearly was very frustrated with the problems he set him. Already Chess24 have announced another longer tour starting in November and running well into 2021. I've said many times that we're not getting back to normal any time soon and we will be reliant on chess online to keep us going.

After a few words about the Armageddon format that decided the Carlsen - Nakamura match, Crowther signed off with:-

There will be more online chess from Saint Louis next month. Right now the Online Chess Olympiad is reaching its climax with some very strong players competing and the many of the usual suspects making it to the final eight next week that decides the prizes. Still plenty to look at.

It's curious that the Olympiad received top-five billing only once in August. In TWIC 1346 it was listed at no.21 out of 23 events, just behind the 'PNWCC Online Blitz - Jackpot XVIII'.

CCC PGN II

Near the end of last year I posted CCC PGN (December 2019), which started,

The 'CCC PGN Archive' (see the tab 'TCEC/CCC Links' at the top of this page) hasn't been updated in over six months, and only shows events through CCC8.

While preparing that post I found a more recent archive and documented its existence in the same tab 'TCEC/CCC Links'. That second archive was only maintained another four months before it, too, stopped being updated. Recently, another attempt was made at documenting CCC PGN files via the site's Discord resource:-

#complaints

the_real_greco 25/07/2020
@LILMAFYA Someone just gave me this, which has a huge number of our old PGNs (I haven't checked it for completeness).

https://cdn.discordapp.com/.../CCCC.xlsx

If it's still missing anything you want (and you're still interested), let me know. You'd actually be doing me a favor if you could point out any that are missing.

See the Discord resource for the full URL of the XLSX file.

I downloaded the XLSX file, loaded it into a database, and discovered that 'huge number' meant 144 PGN files plus one 'TBA'. After doing that, I produced the chart on the left. It shows the number of PGN files per CCC season.

The XLSX data is also useful for a number of other tasks. First, it can be used to crosscheck the older archives mentioned in the original 'CCC PGN' post. Second, I can use it to catalog the CCC-live weekly snapshots that I've been taking for the last year or so. These show the name of the live event that was running at the time of the snapshot, plus events just before the live event.

I didn't have time to complete either of those two other tasks. I'll try to do that another time.

Political Pundits and Pogchamps

For this edition of The Sociology of Chess (November 2016), we return to Pog Champs (June 2020). That was our sociology post of the month when the world was emerging from covid lockdown.

Hikaru on Bobby Fischer, Chess Drama, Iranian Chess Players and other issues (23:24) • '[Published on] Aug 4, 2020'

The description of the video says,

Hikaru [Nakamura] and David Pakman discuss Bobby Fischer, Chess Drama, Levon Aronian, the Iranian chess players and officials, and other controversies in chess.

What does that have to do with 'Pog Champs'? A recent announcement, Chess.com Announces The Next Pogchamps (chess.com; July/August 2020), explains,

Chess.com is announcing the second edition of Pogchamps, the critically-acclaimed Twitch streamer chess tournament featuring some of the most well-known content creators in the world. [...] In preparation for this Pogchamps, top streamers have already begun their training with coaches, including political pundit David Pakman, League of Legends star Gripex90 and others.

Political pundit Pakman has his own Youtube channel: David Pakman Show. Comparing his '962K subscribers' with GMHikaru's '347K subscribers' gives one side of the story, but the clip embedded above has more than 125K views, which would be a decent number even for Pakman.

Why are the two thirty-somethings talking to each other? See The Endgame With David Pakman - A Beginner's Chess Lesson for a Pogchamp (youtube.com; GMHikaru), 'Hikaru gives Pogchamp2 Player David Pakman a beginner chess lesson'. It's called training, but as we all know, there's more to chess than two armies fighting on 64 squares.

TCEC S19 Underway; CCC in 'Pre-CCC15'

Let's start by summarizing this blog's previous report on the world's top two engine vs. engine competitions. The title of that post was Alliestein Wins TCEC Cup 6; CCC Tests 'Stockfish NNUE', and its summary is:-

TCEC: In Cup 6, the AI/NN engines dominated. Alliestein beat Stockfish in the semifinal round, then beat LCZero for the cup title. S19 should start with the Qualification League in the next week • CCC: The CCC announced 'AlphaZero Match Will Be Replicated In Computer Chess Champs' (chess.com). [...] The match should start and finish during the next week.

Both of the 'should start' predictions held true. Following is the current status.

TCEC: Before the start of Season 19 (S19), the TCEC announced its format:-

!next • Now QL, then L3, then testing for L2+L1 including also Stockfish (NNUE) as test opponent, then L2, L1, DivP, Sufi.

It's cryptic, but if you know that QL = Qualification League and L3 = League 3, etc., you understand that the organizers are following the same format they used in S18. An engine with the oxymoronic name 'SlowChess Blitz Classic 2.26' won both QL and L3 by significant margins. The site is now in 'testing for L2+L1'.

CCC: The 'AlphaZero Simulation Match' finished with Lc0 beating Stockfish 8, which was the version of Stockfish used in the 2017 AlphaZero - Stockfish match. Nowhere could I find a W-L-D count of the 200 games from the match and I didn't feel like counting them myself, so here's Chess.com's display of the match.

Stockfish won five games, while Lc0 won a lot more than that. A back of the envelope calculation using the final score of plus-64 yields +69-5=126. A follow-on match Komodo vs. Stockfish 8 was won by the Dragon with a score of plus-30. After that match ended, the CCC started running a series of 'Pre-CCC15' events. A preliminary document showing the planning for CCC15 is available, but is too cryptic to understand. The name will be 'CCC 15: Bullet II' and it should start this week.
