Drawish lines go to a certain depth of course, securing a solid position.  Then
they branch out and I try to pick the branch that might lead to a better
position according to the assessment of the program I am trying to make the
openng book for.

Kind of boring at first sight, but a lot of fun for me.  Takes a lot of time,
but as I am in no hurry, it's not such a big issue.

Sorry about the games.  I might send you one of the versions of the book later
on if you are interested... One time, one guy offer :-), may be only because you
and I are namesakes... :-)
