From Better Backgammon, by Tim Holland

White to play 1-1.

The correct play is to move one man from White’s bar point to White’s 5 point and one man from White’s 6 point to White’s 4 point. The play of bringing four men from your bar point to your 6 point in an attempt to save a gammon is wrong. Unless you hit a blot of Black’s it will be most unlikely that you will not be gammoned, for you would need back-to-back large doubles.

Black’s blotting rolls

It appears that Black will be forced to leave a blot on his next roll. (Only the rolls of 2 and 1 or double 2s avoid a blot.) If you are lucky and hit Black’s blot (assuming he is forced to leave one), you certainly should save a gammon. You will also have a chance of winning.

There is actually a conceivable succession of rolls whereby you could redouble. Let’s assume Black rolls 6 and 5 and bears two men from his 3 point. You then roll 2 and something, hitting his blot. Black then rolls 2 and 1. He enters on your 2 point and is forced to split his men on his 2 point, hitting your remaining man, which is on his 1 point. You will now have the opportunity to pick up both of his blots. Even if you hit only one of them, you will have become a favorite to win the game.
