Inside the Grandmasters' Brains

They're all drunk on low quality vodka when they play.

So basicly what they have proven (or strongly suspect) is that the human brain can adapt to useing specialized heuristics much like the chess programs that they play against(alpha-beta, min-max).

When he had the crayon removed from his brain. "Most people use 10% of their brains. Now I'm one of them!"
Is it that people run on 10% utilization, or 100% utilization 10% of the time?
One interesting finding that Ericcson & Simon found is that if a chess board is arranged in a pattern that could arise during a game, experts were much better than novices at remembering the layout. However, if the same pieces were randomly placed on the board, novices actually performed better!
The really sad thing is that these cognitive photographers don't even cite the relevant literature (e.g., deGroot and Ericcson & Simon), and that they think they've discovered something new. If you read the Nature article, it is apparent that they have a cool tool, and they are studying problems they don't understand. Seriously, reinventing the wheel isn't that impressive.

I got to play Kasparov about 10 years ago, during a visit he made to the states. It's amazing to watch these top players run around to 50 different opponents at a time, immediately move, and win every match. If it wasn't clear from his speed, it was clear from talking to him that he did almost no analysis at each board; rather he "recognized" the position, or recognize how similar it was to positions he'd been in many times before, and remembered his strategy for that position.
At the same time, tho, one of the other things I remember from hearing him talk was that he routinely looks 8 or 9 moves ahead in a game if it does require analysis. I'm sure it's a combination of both skills (pattern matching and analysis) that makes the best the best.

This is not a signature.

I have heard that is a tech myth.

Of course their diffrent, Once a skill, set of moves is used and memorized, the recall of the procedure comes from a diffrent area, especially in vetern players who play from instincts, and experience and not all logical deduction.

This is why a grandmaster can play dozens of people simultanously and win most of the matches, spending only a few seconds at each board before moving on to the board. In essence they are treating each turn on each board as a seperate puzzle, without considering what came before it.
What is interesting is that computers play chess much like amateurs do, by analysing each move and trying to think ahead. However computers are much faster than your average chess player and therefore can suceed at a higher level that a person can.
Or so the Germans would have us believe?
