Huh?

Where's the fuck-up?

There's not much wrong with Gnubg's 2-ply analysis of this position, except that it sees a handful of nonexistent gammon losses. The analysis and rollout game winning chances are pretty close.

Dunno how DC-Ohio is getting his strange results. Is the edit button on? Is deterministic noise in the analysis window set to something other than 0.000?
