You could take the leaves of games as being positions and hang
individual analysis of move choices off those leaves. Each position
where the cube is in play would have a double leaf and
leaves for each of the possible chequer moves. Analysis would be
packed into these leaves. This makes storing hint data particularly
easy. It also would give the structure to make it easy to save the
evaluations used by gnubg when it is playing one of the positions
