Knight Solo

Whenever a chess piece appears solo in a photo or drawing, nine times out of ten it's a chess Knight. Take, for example, another edition of Flickr Friday earlier this year, A Lonely Knight. So far, the photo below has had 2504 views and 41 faves ('favorites', including mine), indicating that its appeal is more than artist inspiration alone.

The description says only,

A recent origami design of mine -- chess knight with a corrugation-based mane.

Eliminating the tags for chess leaves 'origami', 'corrugation', and 'Khepera paper', which leaves little doubt as to its construction. Among the 13 Flickr groups to which it belongs, two groups are for chess:-

The 'Top Contributors' to these groups are also worth exploring.

The Einstellung Effect

Spotted in the March 2014 issue of Scientific American, under the heading 'Psychology'. The introduction on the magazine's contents page said,

The human brain has a dogged tendency to stick with a familiar solution to a problem -- the one that first comes to mind -- and to ignore alternatives, even when they are superior.

The first two pages of the related article are shown in the following image.

'Why Good Thoughts Block Better Ones'

The caption on the right says,

While we are working through a problem, the brain's tendency to stick with familiar ideas can literally blind us to superior solutions.

The article starts,

In a classic 1942 experiment, American psychologist Abraham Luchins asked volunteers to do some basic math by picturing water jugs in their mind. [The participants had to figure out how to transfer liquid between the containers to measure out precisely 100 units.] Luchins presented his volunteers with several more problems that could be solved with essentially the same three steps; they made quick work of them. Yet when he gave them a problem with a simpler and faster solution than the previous tasks, they failed to see it. [...]

The water jug experiment is one of the most famous examples of the Einstellung effect: the human brain's dogged tendency to stick with a familiar solution to a problem -- the one that first comes to mind -- and to ignore alternatives.

What does that have to do with chess?

In recent eye-tracking experiments, familiar ideas blinded chess players to areas of a chessboard that would have provided clues to better solutions.

The article (with a different title?!) is available to subscribers on the magazine's site: Why Your First Idea Can Blind You to a Better One (scientificamerican.com). Another, shorter article on the same site, How Psychologists Study the Einstellung Effect in Chess (also March 2014), deals with the chess experiment: 'Cognitive bias can prevent even the most talented chess players from seeing the swiftest path to victory'.

The full article (with 'PDF Download Available') can be found on Why Good Thoughts Block Better Ones (researchgate.net). As for the illustration of the two geezers playing chess in front of the fireplace -- which caught my attention before the rest of the article -- it can also be seen on the artist's site, Danny Schwartz Illustration.

Articles in Scientific American occasionally focus on chess to make a point. Recent examples that I featured on this blog were Are Boys Good at Chess? (March 2015) and Chess and EEG (December 2014), and there were more posts before those.

While I was looking at the version of the Bilalic & McLeod article on Researchgate.net, the site proposed two more articles by the same authors:-

It turns out the site has an entire category about the game, 'Recommendations: Discover more publications, questions and projects in Chess'. How have I managed to overlook this for so long?

Kids Crafting Tips?

Whatever happened to chess.about.com? As my page linked on the sidebar, 'Chess for All Ages (site)', explains,

From September 2002 to August 2008, I was privileged to serve as the Chess Guide for About.com. During that time, I produced one feature article per week. Although About.com has an exclusive, perpetual license to use my material, it's unlikely that they will ever use it again. After I left, the company gave me permission to reuse the material: 'It would be fine to use your content as you please.' Here are copies of those articles.

First let's have a recap of the site's history, as tracked on this blog. In my last months at the company, when it was still a subsidiary of the New York Times (NYT), I noted a couple of changes at the top:-

In the month that I left, I wrote two posts giving my own perspective from within the company:-

Four years later, the NYT sold the operation to IAC (aka Answers.com, aka Ask.com):-

After that I stopped paying attention to the company, except to check on its content from time to time. I do the same for many chess sites. Wikipedia's page on About.com now goes to Dotdash, with the mention 'Redirected from About.com'. The last paragraph currently informs,

2017–present: Closure of About.com, rebranding to multiple publications under Dotdash • On May 2, 2017, IAC announced that they had renamed About.com to Dotdash, after about a year of transition. CEO Neil Vogel said that the company had lost mind share, and needed to change their marketing strategy. The company elected to refocus on vertical markets through its niche websites: The Balance (personal finance), Lifewire (consumer electronics), The Spruce (home and food), VeryWell (health), TripSavvy (travel), and ThoughtCo (education).

It turns out that chess is now included under 'The Spruce (home and food)', and its current address is thespruce.com/chess-4127460.

The breadcrumb trail for the chess articles shows:-

Improve Engine Hardware - Parts List

Continuing with the previous post in this series, Improve Engine Hardware - Specs, the 'Advanced Chess' (serverchess.com) article from which I gathered the hardware specs, gave me another good lead:-

FirebrandX, a player and blogger on the Chess.com site, advises he's in the process of building a new computer for advanced chess. He revealed his list of components with the estimated street price of only $2325.

The list was part of a discussion about Best CPU for chess engine game analysis (chess.com; March 2013):-

I happen to be in the process of starting a new build. [...] I decided the Intel Hex core [Hexa] was the best way to go instead of the infinitely more expensive Xeon machines.

Another source of detailed information, with links to Amazon.com product pages (and some budget recommendations), is Best Computer Specs for a Chess Engine (castledrook.com; May 2017):-

Make sure that the CPU, motherboard, and RAM you choose are compatible with each other. You can do this by checking the socket information on the store page. [...] The CPU, motherboard, RAM, and cooling are all the most important, so budget most of your money towards those.

The following table gives a side-by-side comparison of those two sources for the 'most important' components.

  2013 2017
CPU Intel i7-3930K Hex Intel Boxed Core i7-6950X
Mobo Asus P9X79 Asus Rampage V Extreme
RAM Ram 64GB G.Skill 64GB (4 x 16GB)
Cooling Heat-sink/fan Corsair H115i Liquid CPU Cooler

The Intel i7-3930 is a 6-core chip, the i7-6950 is a 10-core chip, and the budget recommendation i7-7700 is a 4-core chip. Wikipedia's Intel Core explains,

Intel Core is a line of mid-to-high end consumer, workstation, and enthusiast central processing units (CPU) marketed by Intel Corporation. These processors displaced the existing mid-to-high end Pentium processors of the time, moving the Pentium to the entry level, and bumping the Celeron series of processors to low end.

Identical or more capable versions of Core processors are also sold as Xeon processors for the server and workstation markets. As of June 2017, the lineup of Core processors included the Intel Core i9, Intel Core i7, Intel Core i5, and Intel Core i3, along with the Y - Series Intel Core CPUs.

As for the other recommendations, the table gives enough info for further investigation. At first I was puzzled why chess engine users would want to build their own systems from scratch. Then I realized that it's standard operating procedure in the larger community of gamers.

'A Democratic Game'

Where's the chess capital of the USA? Some people think it's St.Louis, as in How St Louis became America’s chess capital (economist.com), but how many New Yorkers would agree?

Tom D's NYC: Chess (7:52) • 'Comedian and tour guide, Tomas "Tom" Delgado, gives you a quick look around the world of chess in NYC. Shot by Keith Glidewell.'

Shot on location at: Union Square; Washington Square; and Chess Forum, Thompson Street. By one of those coincidences that can't be explained, Chess Forum was featured on this blog a week or so ago: Multi-dimensional Chess Imagery.

Chess Educators of the Year

This edition of Video Friday is in fact a series of six videos, with promises of more to follow. Since 2004, the University of Texas at Dallas has been making an annual 'Chess Educator of the Year' award. The winner in 2010 was Scottish Grandmaster Jonathan Rowson (wikipedia.org).

Chess Educator of the Year - Jonathan Rowson - 2010 (1:06:03) • 'Published on Nov 8, 2017'

For clips of other acceptance addresses from other years, see Chess Educator of the Year (utdallas.edu). Although GM Rowson's work has been mentioned several times on this blog (see, for example, Chess Psychology/Philosophy; June 2013), it was discussed more extensively on my chess960 blog in Rowson's 'Three Types of Theory' (February 2011).

A Collage of Chess Collages

If a picture is worth a thousand words, what are two pictures worth? Ten pictures? A hundred pictures? Last month I used a new (for me) technique to explore the topic of Bogart and Chess in Photos. Based on a snapshot of a Google image search, it was easy to reference individual images, to document their visual connections with other images, and to investigate their origins on the web. The referencing goes something like this:-

Let's use chess notation to identify the three rows of six images. Calling the rows 'A' to 'C' (from top to bottom) and numbering the images in each row '1' to '6' (from left to right).

Here's another example.

Google image search on 'chess collage'

The image in the top row, left ('A1') is from Chess club in a collage (chess.com), where someone meant 'college', but typed 'collage', and someone else gave an example of a chess collage. This must be a common mistake, because Google confirms 'collage' before executing the search.

The image in the bottom row, right ('C5') is from Marcel Dzama: A Game of Chess (seesaa.net). The original image is titled 'The Hyper-modern Revolution' (2011), and is explained as 'Diorama: wood, glass, cardboard, paper, collage, watercolor and ink'. The rest of the page is full of unusual chess imagery. As for the other images in the collage of collages they all tell other stories.

As far as I can tell, I first used the Google image technique (I often call it a 'composite' image) in A Contest With No Prize (September 2012). Lately I've been using it more frequently, for example:-

I've also used the composite technique in other contexts, like:-

What copyright issues are involved? I really don't know. Google freely uses the images returned by a search, without permission from the owning sites. If the owner of an image asked me to remove it (which has happened twice in the 20 years that I've been creating material for the web), I would have to research the question of 'fair use'. In the meantime, I have a few other ideas for chess collages.
