Exactly my point! Opening books containing cooked lines have only one
goal: to get more elopoints on the swedish list and let the consumers
think this is the best program. I don't like this at all.

I think there is a big difference. When humans prepare for a match,
they don't know how the opponent will react to novelties. But in
computerchess everybody can buy the other programs and direct the
openingbook in such a way that your own program always beats the
other one. IMO this is not a good development.

Well, IMO it has nothing to do with improving playing strength!

In this way you could make f.e. the super constellation 200 Elopoints
'stronger'. Not because it really IS stronger, but it has a much better
opening book, full of anti-comp lines...

Here I agree with you. It really is not an easy problem. As far as I am
concerned there would be no learners and cooked lines anymore. But the
reality is different, unfortunately.
