Phoenix tied for first in the 1986 WCCC, and of the four tied entrants, Phoenix
had the weakest hardware.  By 2004 standards, of course Phoenix isn't a good
chess program, but back when it was competing it was quite reasonable.

It's certainly possible to argue that with today's hardware and software
improvements, the history heuristic is no longer a win.  This can be done
without disparaging the strength of Phoenix relative to its competitors, though.
 IIRC, the history heuristic was an important contribution within Schaeffer's
(1986) Ph.D. thesis -- which would not have been the case if the technique
wasn't an improvement on what was known at the time.

I think many people would be interested in experiments done by authors of very
strong current programs, but those seem to be in short supply...
