Two questions:
(1) What percentage of backgammon is skill and what percentage is luck?
(2) How does backgammon compare to other games in this respect?
Question (1) comes up a lot, but it’s a bad question. Backgammon is a game that combines luck and skill, but there’s no simple way to separate the two. If I said, for instance, that backgammon was 80% luck and 20% skill, what exactly would I mean? If someone else said that backgammon was 90% luck and 10% skill, could we devise an experiment that would prove one statement was more accurate than the other? I don’t see how.
