Kerans asked Gelfand about the technique of calculating variations, mentions Alexander Kotov's Think Like A Grandmaster, a book that is now somewhat controversial because e.g. Valery Beim and Vladimir Kramnik have stated that they don't think in “branches of trees” at all.
Gelfand concurred and added: “My search for moves is also chaotic."
Wasn't there some research done years ago that indicated that in terms of the calculation of variations, chess pros and experienced amateurs were about equal. The main difference was that the pros explored different variations.
Yup, I've read this "recently" (last year or so.) It either appears (as a reference) in Coyle's The Talent Code or Greene's Mastery.
Adding to that, pros skipped variations that were "clearly" (for them, well stoked in chunks already) useless, whereas amateurs had to analyse them. So, in terms of width both (may) explore the same, but the pro does it much faster (better pruning AND probably better speed of forecasting moves) and accurately (practice, practice, practice.)
