I have come up with a simple position where GNU Go fails: it is a
position with two ladders. The best move is a double-purpose ladder
breaker at the intersection of the two ladders. GNU Go plays terribly
bad when ladder-breakers are involved. I wonder what other Go
programs
play in the attached position.
But note that white should play K9 to break the ladders.
If white plays K10, then black can reply at K9 to secure both ladders.
Thanks John. I had not noticed that.
Also, I would appreciate if some strong players could check this
position for correctness. I tried to make the position balanced so
that
if White does not play in the center, then it loses the game, and
if it
plays in the center, then it should win. But I am really not sure
at all
whether it is balanced or not.
I agree W loses if he loses both ladders, but the situation if white saves
one ladder is not so clear. Black still holds 4 corners and can reduce
w's territory around the ladder w saved. I'd say the odds are still in
black's favor.
What would you change to make the position more balanced ?
