No significant difference at all, really.  The only conclusion we can
draw from the above results is that all three engines are roughly
in the same ballpark when playing FRC.  We can't claim that Gothmog
is stronger than Glaurung, nor that either engine is better than
Pharaon.

Because of the big difference in strength at normal chess, I think it
is very unlikely that Gothmog is really stronger than Glaurung at FRC.
I am playing a 100 game Noomen match between my two engines
right now, and after 52 games Glaurung is leading by a convincing
34.5-17.5 (+26, -9, =17).  It is very possible that my experimental
and completely untested evaluation changes in the FRC version of
Glaurung hurt the playing strength, but I doubt that this is enough
to make it weaker than Gothmog.

Again, thanks for testing my engines!  It doesn't happen often that
I receive FRC games or results.  :-)
