This is very interesting. I learned chess almost totally by deconstruction (starting with a well worn copy of "Bobby Fisher Teaches Chess") and then practice. I was a passable chess player since I had an excellent memory, but got sort of turned off both by the community at the time (mostly a reflection of the chess players regionally, not in general) and then by feeling that the problem had been solved. It felt like a race of who could memorize the most games. This shows that a much more systemic approach is really occurring. It doesn't do anything for the feeling that chess is solved, however, since a computer can memorize more games than me. That said, I feel it's interesting to see how much this reflects training for other sports. Playing soccer is as much about deconstructing older games, players, then systematically attempting to anticipate their actions and your responses in a variety of contexts (i.e. a search tree). Much of this is instinctive in good players, but the same process is taking place.
