Hi Uri,

as Spike is still only a patzer it needs a good opening book. Spike is a little
weak in opening positions. It does not develop its pieces well if not done by
the book. We are working on this issue :-)

By the way: I don´t think that 20-30 games prove anything. I recently had a
funny effect: I made spike a little faster (about 7%) just to see it getting
worst. In a fixed tournament situation (against one other engine, 100 predefined
positions, book = off) it dropped form 51% to 42% in 200 games. The engine is
doing exactly the same, just a little faster (I compare node count in a WM Test
suite with fixed search depth to prove it does exactly the same).

Greetings Volker
