Wow. This is quite difficult. My volatile cubing threshold drops from its normal 57% to 54% when losing 3 away, 7 away or worse. So Brown should be anxious to cube.
Also, when facing a 25% gammon loss possibility, I normally take at 30%. But, when winning at 3 away, 5 away or worse, I take at 33%. So, White must be quite careful. Another consideration is the fear that White's gammon losses could be worse than 25%, thus White take point may be much higher. Hmmm.
I certainly could be wrong but my choices are:
Best checker play 13/2. I want to make White's cubing decision difficult. After 13/2, cubing is ND/T.
At 13/7 13/8, D/P seems a bit clearer. Be careful, White. Your gammon losses are quite high. Brown, don't be silly. You're losing badly and can perhaps win 4 if you cube and White takes.
13/7 6/5* is a difficult decision for Brown. Gammons are quite high. But there are less good rolls and White can begin to gain fine position if Brown misses. As White, I would hate to take. I would prefer that Brown did not cube. But, there are enough wins to take.
I do not like this problem. All of my analysis could be wrong. And that would be so embarassing that I would wait another 1 1/2 years before posting at this excellent backgammon site. :-)
