Sorry for resurrecting this thread. I noticed something weird here, maybe Xavier can comment. In Henrik's position, XG 3-ply would play a 43: 8/5* 5/1* with a centered cube and 43: 13/9 8/5* with the cube on 2. For all other rolls, as can be seen in the Dice Distribution Window, 3-ply would play the same move for both cases and also 'know' that the resulting equities are equal to at least four digits of precision, whereas ND, 43: 8/5* 5/1* (+0.0220) and DT, 43: 13/9 8/5* (+0.0216, EMG normalisation based on centered cube, I guess) are quite a bit apart. Oh, and after previewing my post, why doesn't the equity of the top play in the first diagram equal the 0.0220 that is shown in the Dice Distribution Window?
