Right, even Jon's hypothesis of a problem due to truncation to exact bearoff/one-sided databases is wrong (I disabled the option and the outcome didn't change). >Is it possible >that the rollout position is initialized so that gnubg skips the >doubling decision? It shouldn't be. The only thing I can imagine is if it is rolled as an "initial position", but it doesn't make sense, especially since the GUI version gets it right ! On the bug-tracker there's a patch proposed by Michel Delpreli : Jon said it didn't solve the problem, but if you understand the intended modification maybe you can get a clue at what's happening ...
