Subject: Star Diamond has a very diverse opening book

I've played a few games against the Star Diamond now.  I gave myself 40 moves in
2.5 hours and the computer 40 moves in *2 minutes*.

0 1/2 0 0 0 0 0 1 1 0 0

I'm weak class C.

Anyway, in all these games there were only 2 or 3 which yielded a "normal"
opening.  When playing humans, my d4 is followed by either d5 or Nf6.

The 4 games I opened with d4 I was greeted with Nf6, e6, and twice with c5.
Interesting.  Afterwards as an experiment I kept playing d4 over many short
games and found it plays d5 only about 12.5% of the time.

With the black pieces I answered e4 with e6.  Twice the computer answered with
Qe2.  Not an unheard of move, but playing it twice was surprising.

Of these 11 serious games, I only was able to achieve a well-known opening about
4 times and went down the side-paths 7 times.  Just seems to me that the
computer plays a very wide opening book, playing side-lines more often than the
main lines.  I think there is a way to observe the opening book by connecting
the Star Diamond to your home PC, I'm going to try that and see with what
frequecy each move is programmed to be played.

I'm quite please with the wide book, by the way.  I spent a lot of time studying
openings in the past.  While this isn't a very good way to improve, I did enjoy
it very much.  But now I want to focus on tactics and endgames, and having a
computer play such a wide variety of opening reduces the urge to study openings
10 moves deep when I know the odds are good the computer will diverge very early
in the game.
