But you can only move what the dice give you, therefore it's an easy best option.

Not sure if I follow you here. I voted for 6/1, which does not leave a shot at all. That's a lot less risk than this 28%. So I disagree strongly that there's an easy best option. The downside from 6/1 is that the "gain" from never getting hit is also much lower, as it leaves a more awkward position than after 11/6.

playBunny's rollout has a too high error margin to tell which play is best, but it's enough to tell that both plays are close. I'm running a longer one at higher settings but that takes days to complete. To be continued.

BTW, have we all donated to blitzxz already?  B)
The fascist's feelings of insecurity run so deep that he desperately needs a classification of some things as successful or superior and other things as failed or inferior. This also underlies the fascist's embracement of concepts like mental illness and IQ tests.  - R.J.V.

Scuse me Zorba, my bad. I thought your vote was to bring down one of the outfield pieces. The 6-1 doesn't do much for me either.

Ah got it, np! All makes more sense now  :laugh:

Full 2-ply rollout:

Spoiler

The plays are very close, and given the standard errors it's too close to call which is best. The 6/1 play wins some more games, but it also loses more gammons.

The equities also point out that we have a small take, this time with good statistical significance: dropping would technically be a 0.0275 error after the 11/6 play.
