This problem doesn't look any easier today than it did yesterday. And although my cube game doesn't have any strengths, these kind seem to burn me on every turn.

I calculate a cubeless takepoint of 30%. Can White win 30%?

Blue's best numbers appear to be deuces since he both gets to the edge of the prime and leaves White to play (and hopefully break the 7-point).

Aces? I don't really think Blue wants to see these as the timing now switches sides (or is very close to switching sides).

Stay on the bar? A double edged sword. Now both deuces and sixes are good for White but most other numbers aren't.

From an overall viewpoint, though, White has three checkers to get past a 5-prime and no spares to work with. Blue has one checker to get to the edge and over a 5-prime, one sure spare and another partial spare. So Blue is definitely ahead by more than a smidgen.

One thing I've seemed to notice about PvP positions is that the small things can really make a difference. It could be quite a bit different if White's spare on the 3-point were on the 6-point, for example. Or if that spare stays on the 3-point but the blot on the acepoint is back higher in the board. Or even if White's sixes (escape and cover) weren't duped -- e.g. if White's blot on the acepoint were actually on the 2-point (a much better place for more reasons than just duplication).

As far as PvP positions go, White is in pretty dire straits. I'm leaning towards a pass. That makes it definitely a cube in my book.

Summary: D+P.
