Thanks Neil.
So this shows that the checker play rollout was rolling out no-double (supposedly too good, as Ian pointed out) for 6/1, and rolling out double-take for 23/18.
It makes sense that it does this, but it makes the checker play rollout misleading.
Something I've thought about for a long time is a system by which a bot could analyze its own rollouts during their generation, to see if it is botching the cube action. A first simple take on such a system could address the situation in this problem. After not too many trials the bot could see from the rollout that the position after 6/1 is not too good, and so it could switch it's cube action. The bot could also report on the cube actions taken. So then you'd get a result of -0.87 (Double-Take) for 23/18, and -1.00 (Double-Pass), -1.06 (Double-Take) for 6/1.
