I just encounterd the position avobe. Blue is on roll. (Obvious no double and beaver)
However, the equity after the double should't be exact 2.000 I thought.
2.000 sounds like White doubles out Blue no matter what Blue rolls.
The truth is that if blue enteres it is usually no double while if she fans it is Too good.
So most likely it is more than 2.000 or less than 2.000. I just couldn't believe that the equity hit the exact 2.000 mark by luck.
So I made a rollout. During the rollout XG shows that equity of White is around 1.835, which make sense to me.
However, once I interrupt it, the main window shows that the equity 2.000 again!
Can anyone know how it happens?
