I actually have quite a few questions about Extreme Gammon but this one has been coming up a lot lately. I've transcribed a lot of books ("Pure Strategy", "501 Essential Backgammon Problems", "Cube like a boss, etc.) so I can use the xg files as sort of quizes and record my progress over time to see where I'm getting better and also where I'm just not learning the lesson. That's the context, here's the question.
