In Response To: Do you know the definition of "solved"? (Ray Kershaw)

Would it in principle be possible to have a computer program to search systematically through all possible positions and conclude definitively for each position whether or not it can be reached from the opening ? Would that take a long time for even the most powerful computers ?

Yes and yes.

Presumably if you could solve that problem you could also solve backgammon.
