Hello Hideki, thank you for the explanation and the info. Stefan Kaitschick: The silly p3 wasnt really a problem, imo that was just a bot-typical let's go home move. P3 was played due to a hardware error (perhaps floating point unit or memory), I strongly believe by observing the log

Hi Hideki, thanks for the information, and congratulations to the new success of Zen. My impression is that Zen (but not programs in general) has no problems to beat human professionals with 4 handicap stones. So, time seems to be ripe to have a try at handicap 3. Of course, as Stefan Kaitschick

Very nice game for Zen. Move 40 almost won the game just by itself. White destroyed b territory so quickly, that Zen decided to show some of its power against whites weak stones. The silly p3 wasnt really a problem, imo that was just a bot-typical let's go home move. Time for Handi 3 games.
