Is handtalk the strongest program?
What does it mean by awarded 3 or 4 kyu diploma by the Nihon Ki-in of Japan?
I bought it a couple of weeks ago and I'm about 10 kyu. I thought it would
be nice to have an always willing stronger opponent to play.
The first time I played against it I gave myself 5 stones and crushed it.
The next time I let Handtalk start the game as black and I crushed it.
As I see it it was 60 bucks down the drain and false marketing. Did I do
something wrong? Is there a special setting for it's strength (besides
Degree)?

Thanks for an answer (by Chen Zhixing maybe), Mans Ullerstam
