What do you mean by "break symmetry"? To me, it means play a move that results in an asymetric board. But why not just detect the symmetric moves and only
simulate one of them?

Valkyria currently play quite narrow book starting with E5. Since the
last tournament I noticed I should try to break symmetry before letting
it think because other wise it could spend a minute on two moves that
are symmetric. But I am considering to widen the choices for Black on
the first move.

Quoting Martin Mueller <[email protected]>:
It is just an experiment that I am running right now. I don't know
which move is better. The M in the version number 1111M indicates
that the program is a modified version. In this case the modification
is that I added or changed a few moves in the book. But I am not
confident in these changes so it is not in the svn. This modified
version will randomly choose either E5 or E4. See the diff below.

I noticed on CGOS that the latest Fuego is starting at the 5-4 point
rather
than the 5-5 point. I know that Fuego uses a book. Does this mean that
analysis of games between strong programs shows that 5-4 is
significantly
better than 5-5?
