Ugly game by the way ![]() ![]() Lots of blunders on both sides. Should have offered this game to my opponent, but perhaps he did not care for the tygem seki error. |

Yeah I don’t know if I was right - I posted while driving, and had to watch out for pedestrians. Maybe not the best idea. I’d recount now, but I have to fix our sink. |

Black made the last play, so if we let White fill the eye in the seki and remove the dead stones the territory and area results should be the same. Then I get Black ahead by 1 pt. on the board. Minus komi that yields a White win by 5.5, which is what Kirby found. ![]() That is also consistent with the result of 8.5 for Black if the seki were Black territory, since that territory would be worth 14 pts. 8.5 - 14 = -5.5. |

Yeah, bad idea. I’ll stop. Don’t worry, I’m not driving in writing this post. |

So the way to beat She at her own game (let's face it, she owns the game right now) is to create lovely big sekis everywhere you can and with her three left thumbs, she will fall over her own feet. Someone should tell KJ. But i'm left with a puzzle: since Leela can't see eyes, and only knows about no suicide, why doesn't she reduce her own groups to a single eye of one point? Ah! Doh! Of course, it's because she can see that if she did that, she would lose. Phew! btw, no problem playing Go on your ubiquitous cellphone (i heard that newborn babies now come out with a cellphone already in the mouth) whilst driving in London, since most of the time you are stationary in a gridlock and in no danger of scoring points for getting pedestrians. btw2, i'd never tried it before, but i let Leela have her head and watched to see what she would do. She immediately went On Tilt both as black and as white, which was one surprise - i had thought they only did that when losing beyond redemption. But an even bigger surprise (perhaps the cause?) was that she became schizophrenic: her left brain arguing with her right about who will win, each 100% sure they were right, with her overmanager averaging them out, coming up with win% of 50% when even i could see it was all over. PS it's kind of humbling to chew on the fact that Leela can knock me on the floor with one hand behind her back, given that she is an even bigger Twit than Papa Don MacDuckface.
