Usually the joseki for this enclosure would be ko for life. But I tried out some variations that White is able to live without Ko. Can anyone show me how to kill White in those situations? I probably played suboptimally as Black. :/ |

Putting an url between the sgf tags does work, so here the problem is just that the file does not exist. |

A comment before I'm able to see the sgf, the kosumi actually generally lives without ko if that's what you are trying. However, the ko tends to be better because it lives larger and leaves more weaknesses for opponent (so usually you can get more with the ko). |

Oh I see Illuck. But its nice to know that it's still invadable when you cant win the ko. As I suck with codes. Here's the url link! http://eidogo.com/#1e4rKzUln. Any vital points I missed or is white truly able to live without Ko ^^

The second move has to be kosumi rather than extend, though. I didn't look into the other variations, but in the first one black S16 at move 11 kills. |

The position that you annotate as miai for life is actually ko, it seems. http://eidogo.com/#18m1m05y8. I guess it's a sort of multi-stage ko for black, so it's not so dangerous for white, but fortunately it's almost a flower-viewing ko for black, as the cost of fighting and losing the ko is essentially just losing the sente at P19. |

Wow thanks for the replies guys. Its really helpful! Does anyone know the kosumi 2nd move that Illuck mentioned. I think he meant white's move. I have an inkling of what he means. But I thought it only works on 4-4 6-4 enclosure. Where after 3-3, white goes kosumi and then another kosumi and connects to a farmer's hat. |
