Not Bad!
Another one: I tried the Ferret-Gandalf testposition, Gambit Fruit Beta 2 needed
12 minutes to play e5 (or Nf5) Gambit Fruit Beta 3 needs 4 and a half, so that
also seems faster.

Gambit Beta 3 seems quite different from Gambit Beta 2. Curious how the relation
is with changes in Toga (1.0) Beta3, if there is a relation? And how they
compare in strength?

(I could not get the .per file to work yet, but at least all the UCI options can
be accessed in ChessPartner interface, although they are not saved upon a reload
of the engine(different in Beta 2? Maybe it's my computer). When testing a lot
of options it is easy to forget switching one on or off but for the the moment
it works.)

(Rebel reductions seem workable, but they also give different main lines so that
might be tunable with other options. Just a very quick impression.)
