From The Backgammon Book, by Oswald Jacoby and John R. Crawford

White to play 5-4.

In Position 81 black doesn’t really have a back game since he holds only one point in the white board, but he is so far behind in the running game (151 to 93) that you are not going to lose the game unless he can hit a blot. You proceed to roll 5-4. Your possible plays are to move two men from your eleven point to your bar point and six point, or two from your ten point to your six and five points.

The correct play is to move the two men from your ten point. The reason is that unless you are quite lucky you will later have to leave a blot. If you maintain your ten point and later leave a blot there, it will be exposed to any 6 (a direct shot) plus some combination shots. But if you move as we suggest, and thus maintain your eleven point instead, and later are forced to leave a blot there, it will be exposed only to 7, a combination shot.
