Sorry, this seems somewhat too simplistic, although I agree we need to
have a coherent and preferrably simple handling of dragon status.
First problem:
5 . . . . . . . . . 5
4 O O O O O O O . . 4
3 . . + . . . O . . 3
2 X X X X X X O . . 2
1 . O O O . X O . . 1
A B C D E F G H J
The lower O string is tactically captured but strategically alive in
seki.
Second problem:
What about multiple semeais?
