Some time later when Heuristic went out of business, he began working part-time for Leiserson at the lab at MIT on the new parallel program ''Star Socrates'', beside his duty as official systems administrator. Star Socrates played a strong World Computer Chess Championship 1995 in Shatin, Hong Kong, finally losing the playoff versus Fritz. Dailey continued his cooperation with Charles Leiserson on the
