Practicing Visualization

During a social time at a professional retreat for my spouse, I found a surprising opportunity to practice board vision and visualization skills. Her group met all afternoon yesterday, and they are meeting all day today. Their work is interesting and engaging, but it differs from mine. I came along to enjoy Eden Valley Guest Ranch (outside Oroville, Washington), and to care for our puppies.

While the planners (that's their profession) work, I enjoy the woods, the views, and the solitude of the cabin. I brought along a chess set and my copy of John Donaldson and Nikolay Minev, Akiba Rubinstein: Uncrowned King (1994). Although the book is old, it is new to me. It arrived in the mail earlier this week. As I read the biographical portions of the book, I play through selected games on the chess board.

One of the games that caught my interest yesterday afternoon was a miniature from the Barman Chess Congress, August 1905. Donaldson and Minev explain that the Hauptturnier was for those who aspired to the rank of master:
Rubinstein made his international debut at the Barmen Chess Congress in August of 1905. Playing in the Hauptturnier, which was comprised of aspiring masters, Akiba turned in an excellent result, scoring 12 points from 15 games to tie for first with Oldrich Duras. (20)
Rubinstein had White against Ernst Heilmann in the second round. Heilmann finished the event in seventh place with 9.5.

1.d4 d5 2.Nf3 e6 3.c4 c5 4.e3 Nf6 5.Nc3 Nc6 6.a3 b6? 7.cxd5 exd5

In the notes, the authors present a few moves from a game that Minev played in 1956. Minev's opponent played 7...Nxd5 and White won a pawn. That game ended drawn, although that bit of information is not in this book.

After spending a bit of time studying Heilmann's errors in this brief game, and looking through a few others in the text, my wife's afternoon session ended. Spouses and others accompanying the retreat participants were invited to dinner and the social time before and after. My wife and I spent half an hour playing with the puppies, then we put them in their kennels with food, water, and toys. We headed back down the hill to the conference center with a few bottles of wine. Others in the group brought some local beer. I opened a couple of our bottles of wine, sampled the beer, and fell into some conversations. A few of the planners whom I was standing with started talking about their afternoon's workshops. Nothing surprising there, but it left me on the margins of the conversation.

It would have been rude to force a change of topic so that I could participate. Instead, I stood quietly, smiling and nodding, keeping others comfortable with my presence. Meanwhile, my mind was back at the table in our cabin. I was playing through Rubinstein -- Heilmann in my head.

In my mental analysis, I made it as far at the diagram in the game score above when I was addressed directly by one of the retreat participants. She showed me some cards the group had worked with earlier that day. The cards were color-coded lists of behavior patterns, mental orientations, personality traits. I matched pretty well with the list on the green card.

Training Log: Taxing Efforts

My continuing tactics training consists of daily exercises using one or more of four electronic resources: Chess.com Tactics Trainer, Shredder iPad app, Chess Tempo, and Chess Informant electronic publications. The Shredder problems are the easiest, but must be solved fast for full credit. Chess Tempo and Chess.com offer rated problem solving. The difficulty of each problem varies, and is determined by the problem's rating. Each problem's rating drops part of a point each time it is successfully solved, and increases when any user of the site fails in the solving effort.

CT offers many solving modes. I use "Standard" where problems are untimed.  CT presents me with problems that range from slightly higher to several hundred below my own current rating. The Chess.com TT has only one rated solving mode. I am not presented with problems 200 points below my present rating. Some problems must be solved quickly, while others allow several minutes. The score is determined by solving time and number of correct moves. Some problems require a single move, while others may require nine or more for the solution to be considered correct.

Chess Informant Expert software allows me to read all volumes of Chess Informant. clicking on a diagram in Combinations, Endgames, Problems, Excellent Moves, or several others opens a solving window. I also use a software application called Chess Informant Solver's Kit to access problems in the Anthology of Chess Combinations. This software is part of the package on the Anthology CD. The Anthology contains many of the most important combinations in the history of chess. The level of difficulty is generally higher than those in the rated solving modes of other resources.

My Monday morning session with Chess.com's Tactics Trainer was frustrating. I attempted fourteen problems, correctly solving half. The electronic environment seems to have undue influence on my board vision. When I do TT on my iPad, the Board is a good size and stable. When I do it on my notebook computer, part of the board is obscure at the bottom of the screen until I adjust with the browser scroll feature. I must make this adjustment at the beginning of each new problem. In contrast, at Chess Tempo, I need only make such an adjustment once at the start of each session.

My longest training session was Tuesday with Chess Tempo (49 problems), but I continued to use several resources. Most days, I solve a few tactics problems first thing in the morning after making coffee, or even while it steeps in the Bodum Press. The convenience of several excellent chess apps for the iPad makes it possible to solve a few chess problems any time that I am in a position of waiting for something else, or during television commercial breaks for my favorite crime dramas (NCIS, Criminal Minds).

On Saturday, my stubbornness led to an initial struggle with psychological nonsense giving way to a marathon session that seemed counterproductive.
