  1. How can it be TG if it's a cash game and the cube is in the middle? (Maybe Jacoby rule is off?) I thought the Jacoby was standard for a money session...Seems like it should either be a double or not a double, no?

  2. I've seen this before with gnubg rollouts. Gnubg systematically over-values the winning chances of the player with the holding game. Therefore it makes bad takes later, which increases the equity of the no-double option.

    It's the first time I've seen this in an XG rollout.
