Yes.  A big thanks to Jorge for playing these matches!

No, they don't even show that.  For engines so close in playing strength, we
need many more games to make such conclusions.  The best data we have so far
concerning the relative strengths of Pharaon and Glaurung is the CEGT rating
list (slow time controls)

http://www.husvankempen.de/nunn/CEGT0507.html

Pharaon 3.3 has 2594 after 93 games, while Glaurung 0.2.4 has 2593 after
126 games.  Not really a big difference. :-)

Of course, the margins of error are still big.  The only thing we know so
far is that there is not a huge difference in playing strength between the
two engines in normal chess.

In FRC the situation is of course even more unclear.  My guess is that
Pharaon is significantly stronger, because Glaurung FRC was released
without any testing at all, and contains some very experimental and
probably unsound evaluation settings.
