eXtreme Gammon Version: 2.19.211.pre-release
A similar position (but not exactly) arose in tonight's NY High Roller semi between Ed O' and Abe Mosseri. To my surprise, Ed (playing dark checkers) refused during several rolls to slot the bar. When questioned later, he explained the deciding factor was that he owned the cube. He was, of course, correct: when owning the cube, slotting the bar is far down on the list and is a 0.05 error. If white owns the cube, slotting (13/7 15/12) is correct. Can someone please explain why this is so? It seems that slotting and covering is the best way to lock up the game, especially with white's weak board.
