Before I go any farther let me address this issue of stealing lines. (I used this term in the last post) It is a fact that some players out there seem to think that if they personally worked out a line or a refutation of one; that they somehow own this series of moves. I find this thinking hilariously funny. It brings to my mind Bobby Fischer jumping up from the table and saying you can’t play that move it is mine, you stole it from my game in the interzonals last year… I call this concept of stealing lines. Fischer thinking. “Look Bobby, once you play the line in open play it belongs to all of us.” This is how, in esoteric disciplines, we collectively learn and advance human knowledge. It is by the possess of peer review that the lines you submit in open play are accepted or rejected. So there is no real stealing of anything only finding and using good ideas. We are all standing on the shoulders of geniuses to be where we are.
Now that you have made your seed book and played some games with it, you are ready to start its development by adding games. Adding games to a book (both your own and kibitz ones) is much different than hand tuning. I think it would be accurate to say that adding games increases the width of the book where as, tuning deals with depth and direction.
It is always best to add games to the book that are played by the book that you are adding them to. This technique has a tendency to reinforce and expand winning lines. However if you find good opening lines while kibitzing do not hesitate to include them into your book.
Lets look at the method of adding the games. First never add games directly to an existing book. Add the games to the database that the book was made from and then make a fresh book from the updated game bases. Importing games into an existing book is probably the most conmen mistake that is made in book making.
Make sure that if you add a game to the learn game base you also add it the main game base.
I recommend that you add all games that you won in online play to the main game base and a selected few that beat you solidly within the first 50 moves. Be more selective as to the games you add to the learn base. Look carefully at your played games; making sure that advantage in the game came from the opening or early in the middle game. (Never add draws, only wins and losses)
Continue to add the games that you play with the seed book back into the book using this technique. Every day review your games, update the game bases (both main base and learn) and remake the book for the next time at online play. This process will slowly but surly expand the books practical repertoire and adjust it to your particular system engine combination. You will begin to notice games that your engine struggled to win now being won easily and good winning lines that were used against you now being played by your book.
At least 2000 games or so should be added to the seed book before you start the hand tuning process. Once you start hand tuning you can no longer add games as red-green marks would be lost.
As always; I am sure that there are many impotent details I have inadvertently forgot to mention. If you get stuck or have a problem please do not hesitate to ask me specific question via email. email@example.com
