fair enough. Thanks a lot for taking the time to explain it.

I came accross this problem while adding a feature to the gnubg based
bot running on dailygammon. DG players will be able to request a
position analysis of positions in finished DG matches. For checker plays
this works already (on the test bot), for cube decisions I'll have to
work around this problem, which isn't difficult at all.
