Hello:
Please somebody send me Bookthinker.exe version that works with the thinker.dat books cooked by Norm Pollock.
Many thanks in advance.
Pablo

Hi Pablo,

I see that the 2 versions of bookthinker.exe that I sent you did not work.

It was easy to make a thinker.dat file provided you know the trick. And I hope the trick still works. The trick is to strip a pgn file before using makebook.

Using the utility pgn-extract and the following line:

pgn-extract -C -V -N -s filename.pgn -oout.pgn

where filename.pgn is your original pgn file (I'll tell you later where to get one) and the output file is out.pgn

Then using out.pgn (which is a stripped version of filename.pgn - no comments, no variations, no nags)

makebook out.pgn (be patient, it goes slowly)

this will output thinker.dat which you can use with the bookthinker.exe that came with the version of makebook.exe that you used.

To get a pgn file suitable for making an opening book, you could for example use the one I recently uploaded to crafty-chess.com.

Hello Norman:
Many thanks for your reply.
I did not receive any of the two bookthinker.exe you sent me.??? Please send them again if possible with their correspondent makebook.exe?s.
I have the feeling that a thinker.dat created with one version of makebook.exe do not work with a bookthinker.exe of other version
My personal email is indech@ctcinternet.cl or sacaf@transam.cl Att. Pablo Urzua
No, I do not have any problem to prepare the pgn files for creating thinker.dat with a makebook.exe.
My problem is that those various Thinker.dat "cooked" by you do not work with my version of BookThinker.exe that came in the last Thinkerboard v.12.a of Sep,2004.
Also I am looking for the first makebook.exe of year 2002 and theinstructions of use (need an special DOS process at the correspondent bookthinker.exe) This makebook create a bookthinker.dat instead of thinker.dat, that works specially in the old winboard engine versions.
Thanks again,
Pablo
