What I do believe is that if for >instance Nimzo programmer know that fritz or junior programs have problems when >they face closed openings where the center is blocked, then the programmer for >Nimzo might select a closed opening when it has to play either of these >programs. ******************************************************************************** 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! Wolfgang
