Not as contrived as the last one. An actual position that came up
recently, tweaked slightly to get an interesting pipcount.

No takers on this one. Perhaps too simple? It's just a race cube, and
there are formulas for that. Here, the appear to disagree. After
penalizing O for the extra crossover, we get a score of 60 to 68. The
three pip wide Trice metric says the doubling window is (64,67) while
the four pip wide Isight puts the doubling window at (64,68)

So it's D/P according to Trice and D/T according to Isight, assuming
I've done the calculation correctly. XG doesn't have a tab for Isight,
but accrording to it, both Thorpe and Keith metrics say it's a take too.

In the variant, I've smoothed out O's distribution, so the take is not a
big an error as it is here.
