Creating an opening book

No, I do not except people to give away their opening secrets, but I was wondering.

How does one create an opening book? I have just been changing options in the fritz or rybka books from green to red and vice versa, but I assume that quite a lot of the decent players on here have proper opening books.

What process did you go through to create these books?

Well, you may probably enter all your lines in a single game, then use the option that makes a book from it !? (as far as I can remember... definitely I should do it again)

Or maybe you can buy it to Ruben :)

Creating an opening book

Hi Garvin,

Book making ia for example in my case always been a very time-intense and manually tuned process. I never do import any outside games to my book.

Guidelines on how to starting out in creating an opening book you can find (or probably have already found), here:

That site got some useful links

General rule of thumb, work on each system one by one. My favourite example: I as white play 1. e4 and Black replies 1....f5, so the Elephant Gambit arises.

Now I want to find good white moves for it, so I enable in my Book allow move adding and check my Correspondence and Playchess Games database for the replies of white. Also I see what major engines think about the moves offered by the database in say 1-2 minute analysis and what these engines themselves gotta offer. This way a reply to the elephant gambit (or maybe more) for move 2 of white can be found.
Also not in any case 1-2 minute analysis will be sufficient. You need to figure this out for yourself.

The less time intensive process: Create a database where you import games filtered by very well chosen criteria (for instance recent games i.e. 2008-2010). Then import the database games into a new empty book.

That's all I know about how it could be done.
