maybe you should try "The backgammon Handbook" by Enno Heyken and Martin
Fischer. As I'am one of the authors, I'am not objective about the book.
I think it's quite a good book. You will find a lot of problems in this
book and I hope, we taught the reader, how to think in backgammon, even
if we sometimes get wrong solution. In the end, there is a match between
two top players. I f you want more informations, send me an e-mail and I
will answer your questions.

Beside our book I recommend two books from Bill Robertie, "Backgammon
for Winners" and "Backgammon for Serious Players".

If youz have some more questions, send me an e-mail and I will answer
your questions, if possible.
