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

[David Schneider-Joseph <david@xxxxxxxxxxx>]

Yes, that is a legal move, and yes, all of black's stones will be captured.

Some ways around this:

1) Program the computer to be at least smart enough to not fill in one of its eyes, if it has two eyes.

2) Program in a "superko" rule.  i.e. a rule which prevents board positions from repeating.  Then your game should theoretically eventually end.

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.
