Definition: The "luck" associated with a roll of the dice is the difference in your equity after you rolled the dice compared to your equity before you rolled the dice. If your equity went up, the roll was lucky; if your equity went down, the roll was unlucky.

As I think you're aware, this doesn't capture all the luck in backgammon, since it doesn't capture what you're calling the "luck" involved in making a checker-play or cube decision.

Let me ask this: Do you think that chess has luck in it? Can you give any example of a "pure skill" task that is not, in effect, a deterministic "measurement"?
