Bots also fill in their own territory removing very distant threats if they can afford to do it. Probably saves a loss in one game out 100 or so.
I am not at all surprised by the phenomenon of half-point victories. One player, who can count perfectly, is trying to maximise its probability of winning. The other player, who cannot count perfectly and knows it, is trying to maximise his score. This naturally produces a half-point win or a large loss for the former. You see a similar result, unintended by either player but a natural outcome of their play, when a human 3-dan gives nine handicap stones to a human 7-kyu. If the 3d attacks a weak group, the 7k tries to make eyes for it, and is not good at telling real eyes from false eyes until it is too late. The 3d tries to stop the group from making real eyes, and is good at telling them from false eyes. The result is that the group makes a string of false eyes, without either player having any particular interest in this outcome. Nick
Petri 2013/6/25 Stefan Kaitschick <[email protected] <mailto:[email protected]>> I have never understood this bot behaviour, because once a position gets very close, every move becomes critical and that should depress the winrate atleast somewhat. The only explanation that I have for myself, is that while the lead is still comfortable, the bot will shun optimal moves if they require any kind of followup, because that looks less safe to the bot.
