Hi Jorge,

Thanks for the interesting game.  I have only had a quick look so far
(and I'm a very weak chess player), but my first impression is that
Glaurung's play looks unsound and too risky.  It got away with it in
this game, but I think it can easily backfire in other games.

There are two important differences between the evaluation functions in
Glaurung FRC and the normal Glaurung.  The FRC version has a much bigger
weight for the space evaluation, and also a big penalty for having
multiple passive pieces.  These two changes are extremely experimental,
and I have no idea how well they work in practise.  Your game makes me
believe that at least the space evaluation should be made more conservative.
