How experts recall chess positions

In 2011, a computer (Watson) outplayed two human Jeopardy champions. In 1997, chess computer Deep Blue defeated chess champion Garry Kasparov. In both cases, the computer “solved” the game—found the right questions or good moves—differently than humans do. Defeating humans in these domains took years of research and programming by teams of engineers, but only with huge advantages in speed, efficiency, memory, and precision could computers compete with much more limited humans. What allows human experts to match wits with custom-designed computers equipped with tremendous processing power?

On the InvisibleGorilla blog (link below), I discuss expert chess memory and embed a video that Chris Chabris and I filmed years ago showing chess Grandmaster Patrick Wolff performing the classic chess-position reconstruction task.

(Here's a direct link to the video, but you should still read the post :-):
