prometheus

Prometheus is an ancient and fully personalized mythological character, prominent already in Hesiod, yet his name is one of transparent meaning. It is a regularly-formed Greek word, and means Forethinker (or perhaps Forethought in the abstract). (Guthrie, 1986)

Prometheus is a conventional chess engine.
