Robertie’s Rule of 65

Black on roll owning a 2-cube, leading 11-3 in a 15-point match.

White’s Pip Count = 126
Black’s Pip Count = 100
Black on roll. Cube action?
Should Black double? If Black doubles, what should White do?

 

You’re playing a 15-point match, and you’ve got a very comfortable lead, 11-3. You were doubled to two early on, and you took. Now you’ve broken contact, and you’ve got a big lead in the race, 26 pips.

Comparing Games of Skill and Chance

Comparing Games of Skill and Chance

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.
