| White to play 2-1. |
It is most important to remember that if you have a choice in making your moves in your inner board, it is vastly preferable to have a man alone on a higher point than to have two men split on the lower points, even if the total number of points necessary to bear off is the same.
You can play your 2-1 in three ways and not leave an odd third man:
- Bear off the man from the 1 point and move the man on the 5 point to the 3 point, leaving a 2-3 position.
- Bear off the man from the 2 point, and move the man on the 5 point to the 4 point, leaving a 1-4 position.
- Bear off the men from both the 1 and the 2 points, leaving only the man on the 5 point.
The 2-3 position can be borne off in one throw in only twenty-five ways. The 1-4 position — remember, it’s the man on the 1 point that makes it better — is good in twenty-nine ways. But the man alone on the 5 is a tower of strength: he can get off in thirty-one ways. And this principle of leaving a single man on a higher point in preference to two men on lower points is consistently valid, no matter what the total number of points needed to bear off may be.
