The promotion system on Tygem is wierd, even thought I lost this game I was still promoted to 13k. Anyway here is a game I played today (I'm White), I guess I played a bit strange but I'm not too sure what I did wrong. After  I knew that I can't win anymore and I also didn't know how to answer this.Where are did I go wrong? |

i ll give it a shot but not stronger than you so .....  : to me this make sense if you have someting arund R10 to buils a sort of moyo. here its too open on the right to generate profit i think.maybe a loose pincer that would developp your G17 stone , say around K17/k16/L16 ? or those funny korean josekis were you frist extend on the side then prevent B extensino on the top instead of protecting the corner ?  i think the common wisdom when B choose the long knight extension from the 4-4 is to play the san-sans invasion instead of D18 but here maybe it would hurt G 17 too much. maybe K 17 now ? those B stones are still eyeless maybe connect at G18 instead ? if B C17 -W C 18-BC16 -WB18 you are alive in the corner AND your are out instead of a floating group. This floating caused you the game i think as he was pursued is painful but how to avoid it ? maybe  @S10 followed by atari atG10 if he hane ? not sure.Then on the following seqeunce he draws a big moyo on the bottom. i think improvments must be in this part of the game.  maybe to shy considering that B J8 is big. maybe H8 instead ? i do not feel its quite resign time yet but what do i know ? smaller than Q 10 i believe --but you did kill his corner in the end BUT it was a gift from B: simply b152 @R19 and black is alive -  pushing from behind while you are safe(ish) and the B stone are attackable. maybe @O7 to threaten to separate ? at least it would create a fight with possibilities of upturn. maybe O7 is not the good move but at least pushing like you did feels submissive

I think w140 @ T17 kills the corner without the ko allowing you to save the N13 group (which cost you about the winning margin). Also leaves you a little stronger for reducing blacks centre territory (and squeezing the win). (disclaimer: i'm a bit weaker than you, so may be missing something) |

(disclaimer: i'm a bit weaker than you, so may be missing something) that's right w140 @ T17 kills but the "normal result" (i think) is seki after B139@T17 W140@T19 |

Thanks perceval! That gives my a very good idea on what I need to work on. @midgie: yes you are right w140 @ T17 kills, it's so easy and I missed it  perceval wrote: that's right w140 @ T17 kills but the "normal result" (i think) is seki after B139@T17 W140@T19 I don't really see a seki there, since my group is most likely alive. |

That's bent four in the corner and dead. |
