Adjournment: An indefinite hiatus for SOTS

It is with regret that I must inform my readers that this blog is going on indefinite hiatus.

Over the past few months (just about 16 weeks, to be more exact), I have found blogging on this site to be a very enjoyable experience. During this time some of these pages gained some recognition as well: through connections formed from this blog, I was offered to write a few book reviews for chesscafe.com. I owe a special thanks to Michael Goeller, a friend and author of the amazing Kenilworthian blog, for his help and occasional reposts.

Unfortunately, as foreshadowed in some recent posts, I simply do not have the time to make this blog all it could be. Rather than be reduced to posting (exclusively) biweekly the Freeze Chess, ChessWords, and Scrambled Chess problems (of which I have quite a few), I decided to simply put the entire operation on hold.

I am currently in a period of significant transition in my life. I am nearing the end of my doctoral studies in biochemistry. In fact, the end to this chapter might come rather quickly, in the order of few months. A great deal of effort might be required to ensure a quick and successful conclusion to some final experiments (not to mention polishing the writing of my manuscript and thesis).

On top of that, my impending graduation necessitates that I intensify my career search. I have been searching for gainful employment for several months. In fact, this blog is partly a piece on the board in that larger struggle, a way to showcase my writing (as well as didactic) abilities in advance of a scientific publication. For my readers that have some connections to science (or otherwise are / or know somebody looking to hire a newly minted PhD), I would be very interested in hearing from you! My resume can be viewed at my LinkedIn profile. 

Hopefully, after I am settled in the next phase of my life, I can return to this blog and resume posting interesting chess stories and analysis, as well as commentary on science. The transition period is bound to be an interesting one, and I look forward to recounting the experience (as well as relating experiences from my graduate career) on these pages.

While I will not be making any new posts for awhile, there is some other work that needs to be done to update some older entries. In particular, I will be fixing some broken links and images in the near future. Also, you should be on the lookout for my favorable review of Dan Heisman's excellent The Worlds Most Instructive Amateur Game Book I recently completed (but not yet featured) for chesscafe.com. When I return, you can expect that I will finish my inconceivable moves series. As a sneak peek, I think that 1.e4 c5 2.Nf3 e5!?* and 1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Qb6 5.Be3! are both marginally playable. I actually have did some preliminary analysis for the latter line (which is essentially a gambit variation in the Grivas Sicilian) at my older blog at chess.com, which you should definitely check out if you haven't already :)

*Intending 3.Nxe5 Qe7 4.d4 Nc6!? (not 4…d6 5.Bb5+ ouch!) 5.Nxc6 Qxe4+

My Worst Blunder of 2012

In 2012, I played quite a few chess games. I was active on Chess.com, playing 41 turn-based correspondence style games (with a 28-8-5 Win-Loss-Draw record), as well as countless blitz games. The story was similar with my over-the-board (in person) play; I had numerous casual blitz and slow games at the Stony Brook Chess Club as well as the Bayshore Chess Club this year. Finally, I participated in 3 different Chess tournaments this year: The Long Island Open (where I placed second in the U1700 section), the Manhattan Open, and the Empire City Open (The last two were played in the New Yorker Hotel, in Manhattan. The facade of the building is shown below). My overall record in these events is 11-5-2 (18 games total, six in each event).

From this collection of games, I could choose several that have egregious blunders, as well as good moves, with varying levels of instructive value. To me, at least at time of writing, my worst blunder of 2012 is clear. This, surprisingly, wasn't even a chess move, but rather my failure to use two half-point byes in the Empire City Open.

Read on the find out why, and see what I learnt about tournament Chess in the process. Have you had tournaments where you wished you took a bye?

To my regular readers, I apologize for the delay in posts, and the fact that there was no Scrambled Chess Sunday Puzzle this past week. In addition to playing in the Empire City Open, I celebrated New Years with my beautiful and wonderful girlfriend at Hunter Mountain. Unfortunately, I became sick the next day! Once I recover and finish some work obligations, you can expect more regular posts and progress.

Book Review: Thinking with Chess

You can find another one of my book reviews at Chesscafe.com. (Previously, I reviewed Walter Browne's "The Stress of Chess".)

This time around, I took a look at "Thinking With Chess", by Dr. Alexey Root. This book is more or less a teaching guide for chess coaches or parents. My review is entitled "Teaching with Challenges", named because the most interesting and valuable part of Dr. Root's book are the challenges. These are essentially mini-games used to exercise a particular chess skill.

The book is put together nicely, but unfortunately I couldn't bring myself to give it a great rating because of the limited amount of material (the size of the book). This is reflected in the concise nature of the review; there was simply not a whole lot to talk about! (My apologies to Dr. Root for any offense, but I'm just trying to deliver an honest opinion.)

Did you read this book? If so, what did you think? What is your favorite book on chess instruction?

Evolutionary Biology and Education

The internet is perennially abound with discussion over evolutionary biology. It is a topic that surfaces repeatedly in the news, either in the form scientific dispatch describing a new species or in political news concerning the friction between science and religion. The latest iteration of the latter debate concerns recent remarks by Florida Senator Marco Rubio when answering a question about the age of the earth. The Senators somewhat ambiguous and confused (but understandable and unsurprising) answer has found both critics and apologists. He eventually qualified his answer, and I think made a good point that I will echo later in the post: the age of the earth has nothing to do with his tasks in the Senate. Even this point has been criticized, but I think it rings true in a subtle way).  Many of these debates, however, usually filter back to the opposition between creationism and evolution (as well as geology, embryology, or any other science that touches on the same points).

(Taken from Joyfully Battle Worn's blog without permission. Interesting post, you should definitely check it out. Echos some of the sentiments I expound here, although approached from a more religious perspective.)

The astute reader may be queuing up their groans and moans (or cheers, if they are into this debate). "Will this blog also devolve into a debate over evolution?" While I thought it would be appropriate to weigh in on the subject (after all, this blog is partly devoted to science, and biology in particular), you need not fear that these pages will transform into another blog taking on evolutionary biology. After all, there are many fine sites that primarily focus on this topic. I am especially familiar (and fond of) some of the more popular ones maintained by other scientists, such as PZ Meyer's Pharyngula. There is even a blog, aptly named EvolutionBlog, that focuses on both evolution and chess!

What then, does Science on the Squares have to offer to the evolution blogosphere? I am trained in molecular biology, not evolutionary biology (although I am well-read on the subject), and thus I will leave the discussion of the finer points of this science to others. However, I would like to add a voice to the debate over the proper placement of evolution in the classroom.

I've beaten about the bush long enough; my point is that neither creationist science, intelligent design, or evolutionary biology (as I understand it to be currently taught) belongs in the science classroom. No, you don't need to adjust your screen or check your glasses: I did indeed call for the partial removal or reform of evolutionary biology from the Science curriculum. 

Now that I have your interest, please select 'Read More' to read this article in its entirety. I'll give you a preview: the evolutionary explanation of the origin of species is more history than it is predictive science, and thus is not critical to the education (or future competitiveness) of our youth.

The position I've taken is one that is sure to stir up controversy, and will probably have the somewhat unique distinction of angering proponents of both evolution and creationism. Please feel free to add to the discussion by leaving a comment below, but try to keep it civil!

The Science of Chess: Moving to the (heart) beat

Recently a team of researchers published an article (PDF format) in which they monitored the heart rate of Chess players during a game (Aptly titled The tell-tale heart: heart rate fluctuations index objective and subjective events during a game of chess. Published in Frontiers in Human Neuroscience, 2012, Vol 6, No 273). 

The same authors of that study have summarized their work for chessbase news in a report also aptly titled: "Psychology: The Heart of Chess". Naturally, I was interested, as I have posted before about the intersection of science of chess and I check PubMed occasionally for such work (although I must have missed this particular study).

Picture reposted (with modifications) from Chessbase. I do not own the rights to the above picture (or for that matter, any of the pictures used in this post).

The article is interesting and thought provoking. There have been many studies that examined some psychological or mental aspect of the game, but there are much fewer (to my knowledge) that studied the physiological manifestations of a chess player's mind. As the article reminds us, Chess is fertile ground for studying all of these phenomenon.

Introduction to Scrambled Chess Puzzles

Here, I will describe a new type of chess puzzle, which I call Scrambled Chess. This is going to be a small example puzzle; I will commence a larger series (Scrambled Sundays!) which will feature full puzzles posted biweekly. (The first one will be posted tomorrow, Dec 2nd!)

Like Freeze Chess and ChessWords, I think Scrambled Chess is a good tool for visualization. In fact, they are probably even better, since they can test visualization skills in several different ways. Also, unlike Freeze Chess (which I developed independently, but are very similar to Bruce Alberston's Chess Mazes), it seems that Scrambled Chess is completely novel. They are also somewhat difficult to explain, but hopefully the example below will make the objective and rules clear.

As an introduction, here is a smaller version of one of these puzzles. (The rules / how to play is described below).

Introduction / Example Puzzle. Movement is Rook by Knight (The notation used for these puzzles will be RxN). Starting Square: A4. Target Square: B1

This is a smaller, 4x4 board (the real puzzle would be a standard 8x8 board). As you can notice, each square is inscribed with the coordinates of another square. The goal is to make piece movements that are legal for both, according to the pieces specified. 

In these puzzles, two pieces will be specified, from the choice of Knight, Bishop or Rook. The first piece dictates the movements that should be taken on the board, while these movements must correspond to legal moves in within the scrambled coordinates.

If the puzzle is Rook by Knight (This one is, as specified by RxN), this means that only Rook moves are allowed, but the correct moves are those to squares with written coordinates that correspond to a Knight move.

The goal is to go from the starting square (shown in brick red) to the target square (shown in blue), making moves that conform to the above rules.

As mentioned above, I will be posting a puzzle every other week, on Sunday (starting tomorrow). Some of these puzzles can be complex, and can be any combination of Rook, Knight, or Bishop moves (RxR, RxN, NxN, NxB, etc). Remember, the first piece dictates movement on the puzzle board, the second piece corresponds to the coordinates inscribed within each square. In this same notation, I have developed puzzles such as Rx2N; what this signifies is that the moves must be with coordinates that correspond to a two move hop of the Knight. 

In the above example, a Rx2N move would be A4-A3, since this uses the inscribed coordinates E4-D5. This corresponds to a two move route of the Knight; E4-f6-D5, or E4-c3-D5. In this particular example, however, that would be a dead end (you cannot read the target square under those conditions).

Stay tuned for a full puzzle tomorrow!

My Excel "FEN to Diagram" Tool

Every Chess blogger and publisher must at one time grapple with the same issue: how to create and display diagrams and games. I have explored and tried a few options, including the pgn4web and chessup.net tools (at time of writing chessup.net server is down). A more detailed list is provided by Michael Goeller's Kenilworthian, among others. Here, I will recount how I came to develop my own, offline solution, an Excel file that converts FEN to chess diagrams.

For a time, I thought I had settled upon using the Chessup.net server, in which I could simply put a FEN string into the URL for the image, and viola, I would have chess diagrams on my site. However, it was unsettling to realized that when their servers went down, so did all the diagrams on my site. I should have saved each image and uploaded them. Even if I had done this, however, the failure of their service would mean that I would need to change the style of diagrams on my blog.

I value consistency when it comes to the appearance of these blog posts. Thus, I began to search for a more reliable, offline solution. However, since I use a Mac. I was found wanting for programs to quickly turn FEN strings into diagrams. My solution: make my own tool to accomplish the same end. I'm a bit of an excel guru, if you might have guessed from my Mutual Information articles (part 1 and 2). Naturally, I chose this program to craft my solution.

Here, I will make available the excel workbook that I have setup to generate all the new diagrams on the site. In order for this tool to work, you must have the Chess Cases font. I will provide the workbook in two different Excel formats: .xlsx, and .xls

Feel free to use this tool as you see fit. I would appreciate a mention if you use it for your site. If you do use it, experience problems, or have suggestions for improvement, I'd love to hear from you. Just drop a comment below!

Read on for more detailed instructions on how to use the Excel Chess Diagram tool. If you are trying to accomplish something special, or need some additional help, I may be able to give you a hand; simply post your inquiry as a comment.
