Hi Arturo,

we had that discussion already in several forums. Uri has his point of view
(which is IMO totally wrong) and will not change that... senseless to discuss...

You might remember CCT4 -> Since then I had never again such a fantastic tuned
book for Quarks needs - it was the work of Leo Dijksman which he had done in
several month with thousands of games and analysis. Of course it was Quark which
was playing that tourney but it had a fantastic book that lead it to positions
it can play. And that is what a good book cooker should do, he should help the
engine to end up in positions after the opening where it knows what it should
do. The more time he can spent on that the better it will do.

Vincencts 700 Elo might be a bit to high, but 300 is for sure a good number -
the difference between a random book and a well tuned book. Especially the
weaker or more unbalanced your engine is, the more it is important to have a
perfect book. Maybe for a weak engine even Vincents 700 is possible...

Greets, Thomas
