Re: computer-go: Is this a legal move?

I solved this by never making a move in territory completly surrounded by my
own stones. This is not so good since you need to do that sometimes, but for
the moment it's not my biggest problem. Another way to solve the problem is
to never fill eyes of size 1,this is also easy to implement.

Subject: computer-go: Is this a legal move?


Sorry if this is an innapropriate message for this list, I am new here (and
new to Go as well). I illustrate with a 5x5 board where W=white, B=black,
and _=vacant intersection):

BBBBB
BBB_B
BBBBB
BBBBB
BBBBB

If it is white's turn to play and they play in the one remaining open
intersection, do they remove all of the black stones from the board? It
would, after all, remove the last remaining liberty of that group. I realize
that this probably never happpens in human play, but I am working on a
computer Go player and, when I play it against itself, the game never seems
to end because it keeps encountering the aforementioned situation and
basically clearing the board, with this play, and starting over.
Thanks,
Todd
