To make clear, I think book learning, however aggressive, is a legitimate offensive and defensive tool, but "learning" of entire games that an existing program is guaranteed to follow I consider to be primitive and having nothing to do with the real competition between programs or programmers. Note that one programmer who was reported to be engaged in this practice has now fallen behind and dropped out of the competition. It is said that no game has ever been won by resigning, and this is true. On the other hand I've never heard of a chess player or program whose strengths include refusing to resign on time.
