Another Backgammon Times position (initially v2#3, later v2#4). This situation arose in the 1982 Indiana Open, with Kathy Posner playing the Blue side. XG says she got this one right. A resident of Upper Darby, PA with the familiar name of Mary Hickey wrote a letter which appeared in the following issue asking about 18/14, 2/1. (Posner only mentioned her own play and the board breaking, double whopper range 6/2, 6/5.)
