Why is the marked move a very bad idea? White has to play at a instead of the marked stone at all costs. |

I thought it is good enough for black to get in move 1 (hane at the head of 3 stones). But if white plays move 8 in this variation, a critical position arises on the board. |

The next moves are forced and black has to start this sequence at once. White plays at a,b or c but black has reached a lead early in the game. Thats why the marked move was a bad idea! possible continuation: |

Additional Info: Most of the time white should play the double hane instead of a. |

Hi Gomoto, Thanks. For the less experienced who may not be able to read as far, there's a nice heuristic in the early chapters of Bruce Wilcox's Contact Fights: the  string has only 4 liberties ( v. 5 for the adjacent  ),and he suggests it could be a warning for ,and that study the situation carefullyto decide if tenuki is wise for :( Of course, he emphasizes all these heuristics are merely guidelines, and extensive reading and global evaluation are key. ) |

The fuseki continues. This is not good for white. White should have played different Josekis. |

But be aware that black should not play the marked stone in this fuseki. This is not a good move. The better options for black are the moves a,b or c. |

If white wants to win it plays like this. This position is very good for white. (black should not follow whites plan like this) |

Nice shortage of liberties tesuji with 7 there. Interestingly enough, I saw AQ play Yoda Norimoto a few days ago (unfortunately game now gone from WBaduk) and AQ as white played the hane block exchange above 7 before tenukiing and allowing black the painful hane at the head of the 3 stone wall (Yoda played marked stone as extend to hoshi though instead of keep pushing). At the time I thought it might be silly bot flitting, but if it was foresight to prevent the tesuji of 7 that's impressive! (AQ made a big centre but not big enough I think, until Yoda made some really dumb misread in yose and a bunch of his stones got captured on the 1st line). |
