Regarding editing lines:

I have Chessbase 7, but there I can't change color coding or instantly add moves
manually (by simply making them on the board), so I use Fritz 8 instead, as I
can do both there. Can you do these two things in Chessbase 9?

I generally color moves intended to be played green, and uncolor moves that I
find inferior. In the start of the book, when there are heavy move stats
determining playing rates of moves, I color moves red to avoid playing them (I
have heard there may be a problem with this method, as the program maybe
sometimes re-color them blue, but I have not noticed this myself).

Then I make sure to check the "use tournament book" option, otherwise I am not
sure the program will play the green moves (if they have bad score weight, it
will try out an uncolored move instead, but I will not let the play be decided
by insufficient statistics).

This is how I manually edit a book, analysing a lot by adding moves to the tree,
and then decide on moves and color them green (or actually, uncolor inferior
alternatives, as new moves added manually are sadly always green by default).

If you want the program to avoid following a "game" which is uncolored (because
usually or often such games will represent play inferior to just engine
calculations), you can set the "minimum games" up, I have set it to 1000 (the
max) myself.

The remaining question is how to start, you can load a lot of games into an
empty tree and take it from there, or you can start with another book and adjust
that one by adding lines you like.

I think one generally good advice for making a successful book is not to enter
explosive or tricky variations unless you have thoroughly prepared your book in
those lines, otherwise your engine will often go straight into positions losing
by force.

Method of work: going through played games and see if the engine had a problem
out of book, and trying to solve it one way or another (adding more moves to
avoid bad continuations, og giving up the variation all together).

I would think that one can only go so far by relying solely on move weights and
move stats. Taking a book to the next level requires continuously adding further
analysis yourself, in my experience.
