can you make an .sgf file of one of these and send it to me - I don't
need the analysis. The only obvious thing I can see from a *very*
quick skim of the code is that it will take when FindCubeDecision()
returns any of:

NODOUBLE_DEADCUBE
NO_REDOUBLE_DEADCUBE
OPTIONAL_DOUBLE_BEAVER
OPTIONAL_DOUBLE_PASS
OPTIONAL_REDOUBLE_PASS

Are any of these likely to have been the state (as viewed by the
master?).

Otherwise the code in external.c:CommandExternal() is incorrect in
some other way - this is *not* the same code as in play.c which is
normally used by gnubg, so it wouldn't surprise me if there may be
some other more fundamental bugs here, since I doubt it's been used
much, if at all. There might be simple silly errors like not switching
sides or setting the player on roll or something when doing the cube
decisions.
