Chess and Go are both simplified examples of "inexact problems" that have no clear solution algorithm. Humans can be quite skilled at these problems, even if it is not clear how they do it. Go is a whole new challenge... Because global changes occur slowly in Go, the game is much better suited to studying complex information management and decision making than is chess.
