If you Google ‘World Backgammon Champions’ you’ll find a number of lists scattered around the web. For the years after 1979, when the tournament moved to Monte Carlo, the lists basically agree except for some minor points like the actual score of the final match. Prior to 1979, however, the lists differ in a number of respects. In this post I’m going to lay out what I think is an accurate list for the period 1967 to 1979, based on printed sources of the time and some conversations with players who were then active. I’ll also explain how some of the discrepancies between the various lists came to be.

Robertie’s Rule of 65
Black on roll owning a 2-cube, leading 11-3 in a 15-point match.
Black’s Pip Count = 100
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.
You’d like to redouble, but you don’t know exactly when it’s right to do so. Clearly it’s right at some point, but – are you there yet?
An Introduction to Backgammon Notation
Backgammon notation is a way of describing dice rolls and moves on a backgammon board. Prior to 1976, notation wasn’t standardized; backgammon writers would invent their own notation systems, and readers would have to learn a new notation system when they picked up a new book. In 1976, Paul Magriel published his classic book Backgammon, using a notation system that was simple and appealing. Almost overnight, this system became a de facto standard, and almost every book published since then has used it. Let’s see how it works.
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.
