an own book anymore and that older book versions didn't work with it,
which is at least no surprise for my Thinkerbooks, because they are made
for other bookless programs and only work with an older BookThinker
version(also available on my download page).
After the above information and a subtle request
I decided
to make another public one which will work at least with Thinker 5.2d.
It is available from my download page and has a max depth of 40 plies.

Edit: I forgot to tell that the other books will be updated too in a few days,
because my main bookbases are already cleaned up again after some
test games.
