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. Finally, it is common to use the words "bar" and "off" to describe moves where checkers are entered from the bar or taken off during bear off. For instance bar/22 17/9, and 5/off 2/off. Backgammon notation Backgammon notation is a
Backgammon move versus following the best move, then averaged for the entire set of taken moves. Neural network research has resulted in three modern proprietary programs, JellyFish, Snowie and eXtreme Gammon as well as the shareware BGBlitz and the free software GNU Backgammon. These programs not only play the game, but offer tools for analyzing games and detailed comparisons of individual moves. The strength of these programs lies in their neural networks' weights tables, which are the result of months of training. Without them, these programs play no better than a human novice. For the bearoff phase, backgammon software usually relies
