I appreciate it, but I fear that it may have one of two effects:
the reader decides it's far too experimental and unstable to be of
interest or they start with an inherent distrust of the program so
that if they find anything non-intuitive or if gnubg's play or analysis
surprises them they shrug it off as "oh, it's still under development"
instead of either reading the documentation to find out how things
work or examining the analysis from gnubg with an open mind to see
that it is in fact right.

GNU Backgammon has a
- Graphical User Interface (GUI) with 2D- or 3D-Animation
- this GUI comes with a selection of board designs to choose from
- there are powerful but simple tools to change or create your own
- you can choose colours, lighting, textures and even the perspective
of the 3D board

- there is a pwerful theory function which allows you to explore
doubling windows, gammon prices and similar cube theory, valuable
for money games and essential for match play
- gnubg has a "temperature map" which gives a graphical simple
overview of the possible results of the next dice roll.

GNU Backgammon comes with several databases for handling bearoffs and
- larger (covering more chequers and more points) bear off data bases
- software is included for generating these larger databases yourself
- databases for hypergammon (1, 2, and 3) are available
- gnubg can use Hugh Sconyers huge databases for races and bearoffs
- gnubg comes with a selection of several Match Equity Tables (METs),
allowing you to change from one to the other with ease.
- it is not difficult to create and use a new MET
