Books on Cube Handling

The doubling cube is such a big part of backgammon that it is rather surprising more books haven't been written on the subject. The reason could be that it is a difficult to give solid criteria for when to double and when to take—this may be an area best learned from experience.

Winning With The Doubling Cube
Peter Bell
Bell's book looks at doubling cube fundmentals: when to double (and when not to), how to evaluate winning chances in a position, when to take, and the psychology of doubling. While it is a good general introduction to the doubling cube, some parts of the book are not very accurate.

The Backgammon Encyclopedia, Volume 1
Kit Woolsey
This is a book of 210 reference positions of "typical" situations you might be in when considering turning the cube. The idea is that by understanding what features make these positions strong enough to double, or strong enough to take, you will be better prepared when similar positions come up your games.

Backgammon Boot Camp
Walter Trice
While not a book devoted to doubling, Backgammon Book Camp has many chapters that deal with cube handling. It contains perhaps more useful information on this topic than any other book.
