You are almost certainly using incorrect scoring. Mogo is a Monte Carlo program and doesn't care if it wins by 1 point or 50, so it will have the behavior you are claiming.
However, it won't lose games that way. If it's passively filling in it's own territory while you steal a won game from it - something is wrong. You should be using area scoring only and if you are playing handicap games then either YOU or MOGO is not counting them the same. Or perhaps Mogo has a bug in the handicap code. - Don terry mcintyre wrote: > I just finished a few 19x19 games with the freely downloadable version > of Mogo, and noticed that Mogo loses a fair number of points in the > endgame. > > I'll email an sgf file shortly, but the pattern is fairly easy to > describe: when territories have been fairly well enclosed, Mogo will > just as often play > inside its own territory as fill a "dame" or neutral point which is > claimed by neither player.
