The computer has to imagine future scenarios which "could" be reached. Then it has to decide which of them would be good to reach. Then it has to see what it can reach even against good play. And that if the plan isn't refuted, so it will be carried out, or better. And if it is refuted, the program must not have become worse as a result. I'm speaking of conjuring up positions independantly of ply count, and before knowing exactly how it will be done. They do that already? I don't think they do that exactly. It's a deep concept I was thinking about it for a long time. And I want to know if any top programmers have any opinion, or could actually do it. The machine would be quite creative! S.Taylor
