Subject: RK 2003 120'/60 Surprising comparison of books

Author: Kurt Utzinger

In the meantime, after round 9.4 total 240 games and 60 games for each engine,
we can see a substantial advantage of using the book general.ctg instaed of
remis.ctg for The King 3.23 skr. Johan de Koning's program got 7,5 points more
and a score of 60 % instead of only  47,5 %. Details on our Homepage "Kurt &
Rolf Chess" http://www.utzingerkurt.com/productssimple3.html. Once again a
good example of the influence of the opening books.
