Is the smaller Zappa book (2600gm.zbook) ok?

I saw book issues discussed in the other thread, but about the 13 MB book. What about the GM book?

Hello Volker & others:

Collecting all the feedback of the people regarding to the big public book, I talked with Anthony Cozzie last night.

Some decisions have been made relate to this issue. The current public big book was the first version of a tuned book. It was supposed to be updated from time to time.

Since people prefer more "normal" openings, Anthony Cozzie will publish a big book generated from a pgn file without nags in the coming days. That is, the current big public book will be substituted by the coming one.
This new book is just a random book without any tuning done by hand.

If I understand correctly, "normal" means known or usual openings. It does not mean that the openings chosen in the current public book were inferior.

I think that this message was required so people are clear and happy with the Zappa?s openings.

Regards, Arturo.

Is this really a good decision? If the author of an engine releases a tuned book, I think the engine is preferably to play using that book, no matter how popular its openings are.

I agree with your point of view, but it is difficult to satisfy everybody I initially proposed Anothony to have a tuned book that could improve during the time. My feedback for this opening book would be the games played in Internet because it was the public book.

Some people were not happy because the current public book plays unusual sidelines that are not inferior in my humble opinion. Other people did not like that Zappa played, for example, a French Exchange because it was drawish and I told them that there were other lines against the French.

Finally, I talked with Anthony Cozzie about this issue and the final decision was to publish a random book with more usual openings but without tuning.

When Anthony has some free time in the coming days, he will update the public book with a random book. Is it covenient? My personal opinion is a random book is just that: No work, no maitenance, no improvements and it will play according to statistics derivated from the source pgn file.

It is not easy to satisfy everybody but a decision was made. I regret that I cannot satisfy everybody but it often happens.
