In fact we change do not change the book when we face another opponent, we just
change the eval. of the moves - to reach a position where we have propably more
opening analysis than our opponent. However - the others are smart too! They try
the same! So the outcome is unpredictable - most likely a position that both had
never before! We'll see tomorrows game of Nimzo vs. Junior. I hope Alex can
mange to get a good line. Good luck Alex - greetings from Austria.

The books from Nimzo and Fritz are more or less the same with different
preferences, Junior and Hiarcs historically use their own books.
Commercial Fritz6 book is basically Nimzo's book from WCCC Paderborn (..some
special lines removed  ,  :-)) and more wide.)

You might find that some other programs are using this book too (..can do it
with some tools) - so bottomline they all again have in fact the same!
