A position in which the same number can be used constructively in more than one way. For example, when your opponent can use a 5 to hit either of two blots, his 5's are said to be duplicated. All else being equal, a position which duplicates the opponent's good numbers is better than one which does not because it means the opponent has fewer good rolls in total. See post by Simon Woodhead.

A backgammon variant in which the players start with all their checkers off the board.  See: How to Play Dutch Backgammon.

[Coined by Danny Kleinman in Double Sixes from the Bar.]  The negative impact on flexibility of having spare checkers exactly six pips apart.
