This review has been printed in the February 2017 issue of Chess Life. A penultimate (and unedited) version of the review is reproduced here. My thanks to the good folks at Chess Life for allowing me to do so.
Gelfand, Boris (with Jacob Aagaard). Dynamic Decision Making in Chess. Glasgow: Quality Chess, 2016. ISBN 978-1784830137. HB 288pp. List $34.95.
Positional Decision Making in Chess, the first volume in Boris Gelfand’s ‘Decision Making’ series, was published by Quality Chess in 2015 to critical acclaim. (See the September 2015 issue of Chess Life for my rapturous review.) Now Gelfand’s second book, Dynamic Decision Making in Chess, is available. Does it live up to the lofty standard set by its predecessor?
The title of Gelfand’s new book accurately describes its contents. His main theme is decision making, with a particular focus on (a) how Gelfand makes practical decisions over the board and (b) his handling of dynamic positions. While Gelfand’s articulation of his thought processes is clear and mainly successful, the lens he uses (dynamical play) makes its complete exploration very difficult.
Gelfand describes the “core” of his books as follows:
I want to explain the thinking that has led to my reasonable success as a chess player, and not ‘cheat’ in the process. It is quite easy to analyze a variation with the engine and then explain why it works. And this certainly has its uses, but to me it is more interesting to talk about how we find the moves in the first place. This is the key to playing better chess. (260)
The goal of the books in this series thus far is to offer an honest accounting of how a super GM like Gelfand decides on his moves. The analysis tries to follow Gelfand’s in-game stream of consciousness, and because he cuts no corners, it can be incredibly complex. A recurring theme of the book is Gelfand’s warnings about overreliance on the computer.
It is a mistake to assume that Grandmasters think like engines. Because humans cannot begin to match the machine in terms of calculation, because we can’t see everything like the computer does, at some point we have to “guess.” (8, 86) Decision making on the basis of limited information (guessing) relies on intuition, evaluation, and judgment. (160, 218, 226).
Gelfand’s point seems to be this: humans cannot calculate their way to good decisions. We must rely on “general considerations” (15) while we play, and we must use our intuition to take decisions that we cannot fully calculate. How do we train intuition, and in this case, how do we train our sense of dynamics?
There’s the rub.
It’s important to be clear about what we’re talking about. Dynamics involves the ephemeral in chess. Some temporary feature of the position must be converted into an lasting advantage before it dissipates. (8) Dynamic chess involves intuition and calculation for Gelfand, but devolves to neither. (9). It is not strictly tactical or strategic in nature, the very distinction being somewhat artificial in his view. (61)
For all of the analysis in Dynamic Decision Making in Chess, and for all of the exquisitely careful explanation of decisions and thought processes, there is nothing to my eye that explains how Gelfand senses dynamism in a position. He just does, and more than that is hard to explain.
This is not a knock on Gelfand (or his co-author Jacob Aagaard). Dynamic Decision Making in Chess is a wonderful book, one of the best of its kind, but like every book on dynamics, there comes a point where analysis and explanation fail and we must simply bear witness to genius.
Again, let me be clear. I am not claiming that the great moves of the masters are somehow ineffable or beyond reason. Instead, what I am arguing follows from the block quote above.
It is easy, as Gelfand notes, to retroactively explain the logic of a brilliant move. What is more difficult is clearly articulating the move’s genesis without falling prey to what John Dewey called the ‘philosopher’s fallacy,’ where the results of analysis are taken to accurately represent what was experienced before analysis began.
Studies of dynamic play are, in my experience, particularly susceptible to this kind of fallacy. While Gelfand works diligently to break down the logic of his best moves – his 11…Ra6!! against Karjakin from the 2009 World Cup, for instance (227-239) – there is a level of analysis beyond which he cannot go. It took him 40 years of study and solving (54, 134) to find such moves, and their intuitive, unconscious origins are not easily excavated.
Does this mean that Dynamic Decision Making in Chess fails in its project? Absolutely not. It may lack the clarity and focus of Positional Decision Making in Chess, but this is due to Gelfand’s ambitious handling of a very difficult subject and his refusal to simplify his thought processes for the sake of expediency. The analysis is best suited for experts and above, but players of all strengths can’t help but learn from this book.
