This is actually a very good analogy to computer chess! At first people tried to fly like the birds, flapping the wings and everything. That didn't work out! The human way of flying now includes fixed wings and jet engines. Nothing at all like the "original", but it works even better. In chess the human GMs don't know how they do it. They just see that some moves are good and some are bad. Their attempts at explaning sounds like "obviously a good move" or "that move is not good in this kind of position". And then they cannot really say what "this kind of position" means. I believe chess skill is something like the skill you need in all kinds of sports. Why are some guys always in front of the goal when the puck or the ball just happens to bounce their way? They just have this special ability, and we call them Ronaldo and Gretzky. Some other guys just happen to be there when good chess moves come their way, and they hardly ever misses the opportunity, Kasparov. Trying to model this in a computer is *somewhat* difficult. :-) So we chose a different way, the thing a computer is good at is computing! Letting it just try *all* the moves, it will eventuall stumble upon the GM's "obvious" move without knowing. However most programs will recognize a good move when it sees one!
