I see. One very important heuristic is that you must somehow recognize eyes, and not fill them up. It is easy to detect an eye shape by looking at a 3x3 square around a point.

Have fun.

Well, the idea can be useful in an alpha-beta search as well. If you give a bonus to a group with eyes, your search will work better.

Yes. Currently I have for eval the end-score (including komi).
