Backgammon notation Similarly, 13/7*/5 denotes a move corresponding to a roll 6-2 and a checker moving from 13 to 5 hitting a checker at the in-between step at point 7. Moves resulting from double rolls are often indicated by placing the number of checkers moved in parentheses after the move. For example, the effect of a roll 2-2, could be: 6/4(3) 13/11.

Historically this was done by hand, but it is now undertaken primarily by computer programs. In order to compare two or more ways to move, rollouts can be performed from the positions after each move. Better choices will yield a more favorable position, and thus will win more times (and lose more rarely) in
