Such a hard balance to get the point right, as always Either extension makes it difficult for Black to come in on the 3-4 point and let White build a wall. But suppose that Black approaches on the 4-5 point and White secures the corner. Then White prefers the longer extension, no? Edit: I wrote 3-5 instead of 4-5. Corrected now. |

Yes, that's true - one of the reasons I picked the closer extension was the 5-4 approach joseki seemed to have perfect shape (high-low 3 point extension), and I wasn't sure if the knight instead of the kosumi to create that shape was too thin... heh, what a crazy game. |

I see I wrote 3-5 when I meant 4-5. Sorry. |

Fascinating, thanks Bill. I chose the tighter extension because I thought it worked better with the 4-5 approach. Having looked closer after your comments, my analysis would be: |

with only a 10 move history going back far in the past will be hard ... i am throwing my lot with , i has been told that points facing a shimari are big. I expect to be take back but i ll learn something. Here is my reasoning I have the feeling that when is high it is sometimes ok to tenuki there but i don't know the specifics. Let the one who take my move back explain a bit my idea is that if W take the corner we will have another big point, say on the left. But if W plays a big point we will have more info to decider whether to block the corner C2 or to play B8 korean style or something else. corrected typos Edit2: as W i would be tempted to play on the left around C10 but that would let B set a perfect double wing formation. |

I mean, if white attacks the leftmost black group from above, the whole left side is looking optimistic. Or white could choose to expand in the right side to R8, and doing so threatens the bottom and right-side black stones. Sorry if I sound a bit harsh, but lately I've been realizing just HOW much I've been suffering for leaving stones unstable and weak. |

I've found that it sometimes helps to just keep a counter of your weak groups. If you have none, then you can play aggressively and invade. If you have just one, you should defend it before you can make another weak group. If you have two weak groups ... pray that they aren't at all near each other. |

It makes perfect sense of course once spelled out. Yes, urgent before big, but usually it s easy to assess that a play is big and difficult to assess how urgent soenthing is. To me this is the true difficulty with that proverb Chew Terr wrote: That's exactly the response I was going to post.

Sorry if I sound a bit harsh, but lately I've been realizing just HOW much I've been suffering for leaving sto nes unstable and weak. not harsh at all, to be fair i was already convinced by your first post above and i just pushed the discussion a bit to enter it further into my thick skull. |

Not getting a weak group here seems like a good idea, regardless of where white or black want to go with this game. Also an extension from top left. The ball is in black's court! |

I like go back. Maybe now perceval's move at the right. |

How do we feel about kibitzing the moves we are thinking of, versus playing a move (including normal planning) and then kibitzing go-back-ing if it seems desirable? I was quite happy with perceval's move and post-discussion-go-back. |
