I think this position may be misplayed in the rollouts. If it keeps the cube for a roll, X may be able to get a incorrect take from O. I guess that what's happening in the rollouts.Five off and one closed out is traditioanlly a take. A GnuBg rollout has it as a pass. I've got no problem with that. What is odd is that the equit of No DOuble is greater than 1. How can this be? That would make it Too Good in a position where no gammons are possible.
This is yet another position where the doubler is seen to win more games by doubling than by holding on to the cube. I would expect O to double X out in some games if O has cube access. Therefore X ought to win less games if he gives up the cube. Something seems wrong. Is it me?
No, I don't think it's you. I think it's GNU BackgammonCan you try to play this position a couple of times against GNU and see if it does somethink funny in subsequent cube actions? (I guess chequerplay will be really simple in this position.)
