Deep heuristic search can achieve expert performance
Deep Thought—the precursor to Deep Blue—plays chess at grandmaster level via deep heuristic search and considering more moves than any previous system.
John Strom & Lindley Darden (1996) argue that Deep Thought demonstrates the effectiveness of deep heuristic search and shows that AI is not, as Dreyfus thinks it is, a degenerating research program; rather, given the success of AI, it may be Dreyfus's criticisms that are degenerating.
