One could use the heuristic that the outside is larger than the
inside, but perhaps a situation can be created where this is not
true. This might even be something beginning Go players could see/
understand.

Attached is a very simple position which adresses the problem of

of inside is that the point is enclosed by stones of one color and/

own wall and/or the border in the same direction and comes back to
the point. But in the given position a3 and all the other 257
intersections are according this definition also "inside". It
would never come to the mind of a human player the the 3 black
stones enclose the 257 intersections.
The message is: Tasks which are for a human completly trivial are
hard to formalize.
