This position didn't come up in real life (for me, anyway), but a similar one did and I modified it to find the real cube takepoint. This is it. So if you're just trying to "get the right answer" then you did, if you tried, because it doesn't matter if you take or pass.
But there was a lesson for me, and maybe for you, too. Because the buried cube takepoint (takepoint if Blue buries the cube, promising never to use it) is 22.7% Cubeless Game Winning Chances (cGWC) whereas the 100% efficient cube takepoint (assuming Blue will be able to redouble at a point that White will have no difference in his drop/take decision) is 17.0%.
The value of the below position is that it tells what the cube efficiency is for such a late game drop/take decision and it's only about 39% efficient, not the typical/canonical 70%. This is found by seeing how far the real cube takepoint (20.5% found in the rollout) is between the buried cube takepoint and the perfectly efficient recube takepoint.
