Wilhelm Hanstein, Schachzeitung

Continuing with a recent post, Berliner 'Schachzeitung', I wrote,

I discovered that various 19th century chess periodicals were available via Google Books. My first effort concentrated on 'Schachzeitung', which, according to Di Felice's 'Chess Periodicals, 1836-2008', was published during 26 years.

There is such an enormous amount of material in these 'Schachzeitung' volumes that I can do little more than examine an occasional curiosity. For example, the image below left shows one of the first pages in volume 5, 1850. The signature says, 'W.Hanstein'. The image on the right is the first page of his obituary. I've done so little work on this particular volume that I'm not even sure in what month the obituary was published. Based on the PDF page number (which is p.337 in the original volume) and on other visual clues, I guess it's the first page of the November 1850 issue.

Schachzeitung [v05; 1850], PDF p.8 & p.359

In Wilhelm Hanstein, Wikipedia informs,

Wilhelm Hanstein (3 August 1811 in Berlin – 14 October 1850 in Magdeburg) was a German chess player and writer. Hanstein was one of the Berlin Pleiades. He helped found Berliner Schachzeitung, later to become Deutsche Schachzeitung. He was a civil servant.

Those are the first three of the five sentences on the Wikipedia page. Hanstein's obituary in Schachzeitung is 13 pages long.

What does the obituary say? My knowledge of the German language isn't sufficient to translate the original text, so I turned to some aids. First I ran the initial paragraph of the PDF scan through an OCR conversion. Then I ran the OCR output text through Google Translate. Here's what I got:-

A hard blow hit us! - As in the narrower
circles of friends, so also in the common fatherland,
yes we can say in Europe and over the ocean, the
news of this loss in each of the great master,
knew the sensible poet, the deepest conscience
he egen.

To facilitate comparison, the line breaks correspond to the original German text. The paragraph makes some sense until the last line, where the phrase 'er egen' is translated as 'he egen'. In fact, 'er egen' is undoubtedly a single word where the third letter is missing from the PDF scan. For some reason, missing characters occur frequently, not only in the Schachzeitung scans, but in other scans that have nothing to do with chess. Add this to the (long) list of things that can go wrong with digitized documents. Also add 'Pleiades' to the list of topics for future Schachzeitung posts.


Later: Re 'I guess it's the first page of the November 1850 issue', if I had checked the table of contents, which is separated into months, I would have seen that the obituary was the first page of the October 1850 issue. I excluded this possibility because Hanstein died 14 October 1850. He was only 39 years old.

TCEC S15 Div4 Finishes; Stockfish Wins CCC6

In last week's post on two top ongoing engine competitions, TCEC S15, CCC6 S3 : Both Underway, the title hinted that both events were just getting started.

TCEC: The first event, 'S15 - Division 4a', has already finished and 'Division 4b' is underway. • CCC6: The 200-game [final] match started two days ago and is moving quickly, with about 1/4 of the games already finished.

A week is a long time in an engine tournament and those stages have finished and morphed into other events.

TCEC: TCEC S15 division 3 is currently underway. The two top placed engines in divisions 4a and 4b all met in a playoff, from which the two top engines qualified into division 3. The AI/NN engine AllieStein (Allie + Stein) was one of the two qualifying. The TCEC also published a wrapup report on S14:-

TCEC deserves credit for setting the standard in engine competitions.

CCC: Just as in the latest TCEC final (see the February post, Stockfish Wins TCEC S14) Stockfish edged Leela in the CCC6 final match. The following chart shows the game-by-game result of the match (10 rows with 20 games per row) from the Stockfish point of view.

Stockfish score: +19-16=165 (101.5-98.5)

In the two days since the match ended, the chart is the only official record published by Chess.com. Let's hope the match PGN will also be made available.

According to reports on other sites, the site is preparing CCC7. In the meantime, it is conducting the 'Bongcloud Bonus (10|10)', where ten top engines are forced to start the game with 1.e4 e5 2.Ke2. Ugh! Which engine will achieve the most most draws as White?

I'm a big fan of unorthodox openings, but attacking with the King on the second move is void of interest. Since there are so many better ideas for a thematic tournament, you have to ask what the organizers were smoking.

Stock Post

As far as I can tell, stock chess photos are mainly used to illustrate articles that have nothing to do with chess, except through an indirect reference. 'To avoid checkmating your budget, ...', stuff like that.

The description said,

Stock Photos / Fotos Download • Please leave a comment and add my picture to your favourites • Thanks and greetings from Cologne, Germany

The photographer also added a comment that showed more stock photos, some of them having nothing to do with chess. I added the photo to my favorites, but decided against leaving a comment. When I first started this Flickr series, I routinely added a comment to the original photo with a link to my post. I can't remember why I stopped.

Berliner 'Schachzeitung'

After last week's Closing an AI/NN Chapter, I returned to last month's Down the Rabbit Hole, where I discovered that various 19th century chess periodicals were available via Google Books. My first effort concentrated on 'Schachzeitung', which, according to Di Felice's 'Chess Periodicals, 1836-2008', was published during 26 years:-

2321. Schachzeitung: In Monatl (1846–1871) Organization Berliner Schachgesellschaft. Vol.1 (1846)– Vol.26, no.12 (Dec 1871).

In a related post, 'On Anderssen' (February 2019), I mentioned,

So far I've collected 23 of the first 26 annual editions of Schachzeitung (1846-1871).

I eventually located the three missing volumes, meaning that Google Books has the complete series. Here is the title page and the first page of the table of contents (TOC) for the first volume. Publishing started in July 1846.

As useful as these magazines are for documenting the development of chess in the mid-19th century, they are not perfect. Some problems were introduced when the individual issues were initially published (there are very few dates to confirm the period covered) and others were introduced when the issues were bound into an annual volume (wrong dates, incorrect TOCs). Other problems arose during the scanning process (blurred or missing pages). Google supplies only minimum descriptions, sometimes wrong, to identify scanned files and only a visual check of a document can determine its true content.

Fortunately there are multiple scanned copies of many documents, gathered from different physical libraries around the world. If one scan turns out to be bad, another is often available. While I was collecting the 26 volumes of the Berliner Schachgesellschaft's 'Schachzeitung', I noted other periodicals having 'Schachzeitung' in their title. I'll cover these in another post.

Celebrity Chess Players

Curious about which chess players have celebrity status, I asked the oracle. It told me which celebrities play chess. It also drew a picture for me, captured below.

Google search on 'chess celebrities'

That link goes to Chess Playing Celebrities (imdb.com), where 50 people are listed. Some of them I've never heard of, but most are bona fide celebrities. Beneath the search box displayed above is some small print that says, '(?) About this result', and that leads to Featured snippets in search - Search Console Help (support.google.com). There I learned,

When a user asks a question in Google Search, we might show a search result in a special featured snippet block at the top of the search results page. This featured snippet block includes a summary of the answer, extracted from a webpage, plus a link to the page, the page title and URL.

So that box is called a search 'snippet'. The page also explains how page owners can prevent their content from appearing in snippets -- a copyright notice is not sufficient -- and ends with a Q&A exchange:-

Q: Is this part of Knowledge Graph? • A: No, this is a normal search result, emphasized with special layout.'

Knowledge Graph? It turns out it's the box that Google displays to the right on the first page of search results, so that you don't have to click on any of the results. Wikipedia starts its explanation of Knowledge Graph by saying,

The Knowledge Graph is a knowledge base used by Google and its services to enhance its search engine's results with information gathered from a variety of sources. The information is presented to users in an infobox next to the search results.

The article goes on to complain that this particular Google feature leads to 'Declining Wikipedia article readerships'. So Wikipedia takes content from all over the web and Google takes content from Wikipedia and no one goes to the original content. Is there no honor among thieves?

Meanwhile, I still don't know which chess players have celebrity status. Maybe none of them do.

A Not So Googly Gadget

A few months ago, in a post titled A Googly Gadget (October 2018) on my chess960 blog, I wrote about a Google search result called 'Your Site on Google'. Everything I wrote about it is still true and I won't repeat it here, but this week I received the same result for a search on 'chess'. The following image captures what it looks like.

Google search on 'chess'

I know that chess960 is a very small topic and I wasn't too surprised to see my site had a search presence there. Chess is a much larger topic, with thousands of relevant pages, and I'm certain that my site isn't appearing for a simple query on 'chess'. It might appear for 'origin of chess' or 'chess setup', but not for 'chess'. The most important info in the image above says,

See how your site has been showing for this query for the past 90 days and compare to the previous 90 days:
- Clicks 3
- Impressions 116
- Average position 9,7

'Average position 9,7' means that the site is shown on the first page of results. That's where you normally see big chess sites like chess.com, wikipedia.org/chess, lichess.org, etc. etc. Little sites like mine are buried many pages deep, if they show up at all. I double checked this by clicking to the second page of results, the third, etc. etc., and, as I expected, there was no trace of my pages. The results stopped at 17 pages, where I received the message,

In order to show you the most relevant results, we have omitted some entries very similar to the 170 already displayed.

That sort of message is normally shown at the end of queries that produce only a few pages of results. Now we go from the first page ('About 262.000.000 results') to the last page ('Page 17 of about 168 results') with a few million pages ignored along the way. Have I stumbled on a temporary discrepancy or has Google changed something fundamental to its search?

TCEC S15, CCC6 S3 : Both Underway

In last week's post, TCEC S14/S15 Interlude; CCC6 S2 Wrapping Up, we left the two ongoing engine-to-engine competitions both preparing for their respective next stages. What has happened since then?

TCEC: In the 'S14/S15 Interlude' segment of the post I mentioned 'three short competitions', aka bonus events, that were conducted between the end of S14 and the start of S15:-

The first event was a 48-game three-way match that lasted a day or so. • The second event was a 240-game four-way round robin featuring the four top engines: Houdini, Komodo, Leela (LCZero), Stockfish. I couldn't find a final crosstable for the event, although the final PGN is available in the TCEC archive. • The third event was a 100-game match between Stockfish and Leela that lasted about three days.

It turned out that I was referring to an old archive, one that uses the site's old GUI. A new archive, based on the new GUI, is at tcecbeta.club/archive, under 'Seasons', and has all of the info that I was looking for last week. I added the new archive link to the 'TCEC/CCC Links' tab at the top of this page. For the S15 kickoff report from TCEC, see

The report includes a list of competitors for each stage of the new season. The first event, 'S15 - Division 4a', has already finished and 'Division 4b' is underway.

CCC: Chess.com issued a report on the current status of its CCC:-

The 200-game match started two days ago and is moving quickly, with about 1/4 of the games already finished. The two engines, Stockfish and Leela (Lc0), are running neck-and-neck.
