In Response To: Match recube. Rollout & MORE VARIANTS (Nack Ballard)

I am following up on this post.

Comparing the original position, Variant 1 and Variant 2...

With Blue's blot on the 15pt, proper cube action is Redouble / Pass.
With his blot moved to the 16pt, proper cube action is Redouble / Take.
With his blot moved to the 18pt, proper cube action is No Redouble.

While it is true that the redoubling window in this score situation is narrow, why is it that improving Blue's timing (by a pip or three) should weaken his position?

No one asked the question or otherwise commented. I doubt that everyone (if anyone) who read the post saw the true explanation and found it unremarkable, so I find myself wondering if in general folks coming across counterintuitive rollout results lack the curiosity to figure out or at least find out what's going on.

In Variants 1 and 2, in what seems to be just as safe a position as the original, Blue leaves a direct shot with 55. In Variant 2 only, double 1s in an added (albeit lesser) problem.
