A program stronger 150 points than another will win nearly all games no matter how bad it comes out from the openings. 2. The stronger the program is the most important the book is. Of course weak lines should be checked and removed to avoid loosing positions. 3. The weaker the program is the less the book is important. The reason is that it will find very many positions where it does not know how to play them. P.N. Do not take the Shredder - Hydra example to state the opposite, because I knew we had some weak lines in the book, but for personal reasons could not work on them. Of course anybody can state the opposite, but my statements are supported by thousand of games and more than 100 engines/prototype testing at all level and with very many different harware. I have no time and williness to do deeper into these matters, so it is up to you to believe me or not. Sandro
