In Response To: Four-score position from "Backgammon Openings" (Nack Ballard)

The position posted at the bottom of my previous post is probably not quite a T4. Again, the best dmp play, @ (anchor, 24/18(2)) topped the XG2 3-ply money rollout, though this time by only .001.

I could extend the rollout beyond its current 62k or roll it out on 4-ply with a chance to overturn, but I'm not really satified with a mere T4 anyway.

What I am after is an R4 (real four-score position, which means that no best play is even as close as "tied" at the other three scores). The good news is that a couple of days ago I did find an R4, a variant of the published position. I'll post it, along with supporting rollout results, soon.
