Backgammon software employing neural net techniques have revolutionized both the practice and study of backgammon, as they have proven stronger than their human opponents.  Since the ‘bot revolution, players have been able to enter backgammon positions, games and matches into software programs to see how these mindless but ruthless programs would play them.  Then the trick is to figure out why — because they don’t talk much. While you can practice by playing against them, it’s often more effective to set up a position you hope to master — for instance containing a checker after a late hit in the bear off — and play it repeatedly, looking for patterns in how the ‘bot goes about the task. Note that all of these programs have customizable board styles, so don’t judge  them by appearances — click on the screen image to visit their websites.
