Rollout: Duplicated 2's

In Response To: Duplicated 2's (Timothy Chow)

Here I tried 24/22 4/1* with the idea that if I rolled a 6, I could put that back checker to good use. The rollout puts 6/4 6/3 on top. I think that if I were allowed to play just the 2 and not the 3 then 24/22 would be as good as or better than 6/4, but that 4/1* puts a checker out of play and so 6/4 6/3 is better overall. However, it's not obvious to me how to test this theory.
