When I left for work this morning, several rollouts were showing double / drop after the initial roll. When I returned, they had reversed by a very small amount. The rollouts are short and inadequate, so they would not have been conclusive anyway. At this point, I don't have evidence of an initial roll that is a drop. (That's assuming you made the best move of course.) So, taking the cube after any initial roll appears to be a reasonable stance.

Here's a close one. A deeper rollout is needed. If you play 52D, you need to drop.

1. Rollout 24/22 13/8 Eq.: -0.9973

0.4976 0.1936 0.0347 - 0.5024 0.1407 0.0199 CL -0.3000 CF -0.9973

[0.0023 0.0062 0.0038 - 0.0023 0.0021 0.0027 CL 0.0065 CF 0.0100]

Full cubeful rollout with var.redn.

1182 games, Mersenne Twister dice gen. with seed 810560163 and quasi-random dice

Play: world class 2-ply cubeful prune [world class]

keep the first 0 0-ply moves and up to 8 more moves within equity 0.16

Skip pruning for 1-ply moves.

Cube: 2-ply cubeful prune [world class]

2. Rollout 13/11 13/8 Eq.: -1.0357 ( -0.0385)

0.4914 0.2222 0.0411 - 0.5086 0.1467 0.0257 CL -0.3250 CF -1.0017

[0.0024 0.0067 0.0041 - 0.0024 0.0024 0.0037 CL 0.0070 CF 0.0105]
