White to play 5-1

In backgammon, much of our thinking revolves around assets. What asset can we acquire with a given roll? What asset do we have to give up? One way to look at backgammon is as a series of decisions regarding the accumulation of assets, and the conversion of one asset into another.

Some assets are quasi-permanent, like inner-board points, or primes. Others are more ephemeral, like a racing lead, which can vanish with a single hit. We tend to prefer permanent assets to temporary assets when we have a choice, although usually we’re happy to get any kind of asset we can.

White to play 4-2.

If you understood the logic behind our last problem, you should have no trouble with this one, although the two positions belong to different categories. Our last problem was what I call a ‘One Man Back’ position, where the issue was to move up in the board and try to get into a race, or stay back and wait for a better chance later. This position belongs in a category I call ‘Split or Something Else’, where one choice is to split the back checkers and go for an anchor, while the other choice is something different, like making an offensive point, bringing down builders, or just waiting. In this case Play A is splitting with 24/20 13/11, while Play B is to wait with 13/7, gobbling up some of White’s timing in the process.

White to play 4-4.

This position was originally Problem 166, where Black had just danced and the question was whether or not White should double. (The answer was borderline double/no double, and easy take.) Some of the responders asked how White should play a subsequent 4-4, and that did seem like an interesting idea for a problem, so here it is.
