| Post subject: | Game review : 2k KGS |
Hello, I tried to get back to playing after a short stop... I thought I would do it right and review it / get it reviewed. I've made my own comments and raised questions along the file. The most critical one are numbered 1/ to 6/. Feel free to answer any other one you see fit. Many thanks in advance to those who will spend the time to look at the file and comment it. Cheers, |

A few comments: @move 8 Quote: I failed to recognize the "Kobayashi opening". You're still failing. He didn't play Kobayashi. @move 42 Quote: Is the sequence correct here? I'd say you should s8 before s14, seems like a very crucial exchange. (And if he responds with a hane instead of a descent you can even capture q11. If that's a bright idea is another question.) @move 58 Quote: 4/ Is it too early? A move at A would have been big. I felt I had to erode that power but Black got so much reinforcement in the process... I don't think too early, rather too late. Instead of s7 earlier I would probably have q8. Looks slightly dangerous, but being able to run out with p11 is a constant threat, so black isn't immortal either, and looks like you only need one eye inside black's center, which shouldn't be very hard. @move 100 Quote: Is crosscut better? I don't really know, but since it doesn't look like you can live locally, I would first attach at c13 and then later decide how to use c9. |

Basically I thought Kobayashi was black 7 at d10. The senseis page you linked says one major variant is black 7 at d11. (In the game black 7 is at d9 and leaves quite an easy invasion for white, but who knows, maybe anything 4th line that reinforces both the open komoku and the hoshi approach *somehow* is called Kobayashi.) |

It seems this pattern was played by a few strong players on KGS and managed as Kobayashi but my pro games database doesn't have this move in it. leichtloeslich wrote: @move 42 I'd say you should s8 before s14, seems like a very crucial exchange. (And if he responds with a hane instead of a descent you can even capture q11. If that's a bright idea is another question.) Interesting idea. I felt compelled to save my group but I missed any sente move I could play around. The exchange of S8 for T9 feels a bit favorable for Black though as it damages both sides at once. leichtloeslich wrote: @move 58 Instead of s7 earlier I would probably have q8.

Yes. I like that. From a shape standpoint, it's so much better. Also, it's much more active. leichtloeslich wrote: @move 100 I don't really know, but since it doesn't look like you can live locally, I would first attach at c13 and then later decide how to use c9. Good point, while it may not help in the end result, it commits fewer stones to the same effort. Thanks for your comments. |

 ,  ,  ,  : everyone missed the big shared vital point Q5 ? feels small and not urgent: B has an open skirt anyway, thanks to  .( Other points are bigger; for example, L16, or B's left moyo. )  very happy to reply as you did. both of you missed Q5 for so long. Locally, maybe possible to consider the ko Q7. probably part of the problem was .

EdLee wrote: feels small and not urgent: B has an open skirt anyway, thanks to .( Other points are bigger; for example, L16, or B's left moyo. ) Yes, I should have delayed this move. I thought Black had to add a move there and therefore I would profit from "punishing". I clearly didn't give enough thought to my opponent move at  EdLee wrote: very happy to reply as you did.OK. Thanks for confirming. EdLee wrote: both of you missed Q5 for so long. Locally, maybe possible to consider the ko Q7.Thought about it but I assumed I would get away with it. After Black enclose my group, I feel really bad. EdLee wrote: probably part of the problem was .Do you think S17 was too small? It seems like the usual move in this position. Thanks a lot for your comments. |

S17 feels quite natural to me, but I could be wrong.
