With respect to books you are surely wrong Harald. The program (CM_9000) using
the Kostick.btk (converted Kostik.opk) has a disadvantage vs the top modern
commercial books of Deep Fritz, Hiarcs8 and so on. That was the reason why we
gave all program the same remis.ctg book. This book does not at all include
lines that lead to drawish games, but the programs are at the same moment out of
book in balanced (positional/dynamical) situations.
