sprt @ 10+0.1 th 1 Don't run NMP if (a) we had no choices (other than excludedMove) on our last turn, and (b) our opponent did. This sounds like a possibly zugzwang position. (Difference from previous version: take 1 included chains of forced moves; this does not.)

sprt @ 60+0.6 th 1 I'm confident in STC gain, due to multiple similar long yellow runs. But there's no point in continued efforts if none of this replicates at LTC--so pause further STC attempts and attempt speculative LTC for 65K yellow. Low throughput.

sprt @ 60+0.6 th 1 I don't know if the 132K STC is actually better than the last one...but the framework isn't busy, so try once more. If this fails, I am probably out of ideas on this branch (and welcome new ones!).
