Trigger: I combined the komi and the captures in the caption.
Not for you: I get sente anyway. It's not bad for white at all; I'm 90% sure this line is considered joseki. It just feels too straightforward, I guess. I get stuffed in to the corner (though it's a pretty big corner, if I want it to be). I just don't like 5-3 stones. Can't I have the corner territory and outside influence? |

Not for players I extremely doubt this line is joseki on this board because the ladder breaker threat doesn't exist. |

i ll take the trigger
what i wanted from the start so i am happy: I got a fat top. what is nice is that there wont be pesky ladder breaker threateing to save Q19 Edit: i was sad aboutnot getting sente but maybe he has to add a move in the corner ? that would be cool. i wonder if we played joseki. it seems normal to me at least except that W corner is maybe too big on a normal board ? |

Guess I'll just take corner profit :/ This is on the verge of being an overplay, but I think it works because of black's shortage of liberties (without the Q19 stone this wouldn't work). For example, black looks in good shape until he realizes he still needs to defend at 6.

goal is to shut him in, standard when you surround a corner. i was a little worried about the crosscut
but thise sounds good enough : W is still capture and the cutting stone is unhappy ?

Is he going to respond or is he going to give me sente? Is there a response that I need to take gote to respond to? (I don't think so). |

i considered:
-g can be left for later i feel The obvious move i want to play is T19 but i have trouble making it work because of the aji of
if i play away i am annoyed by the cut
i can play twice at the bottom but its inconsistent with blocking in the first plqce ? local move to defend the cut lose sente. i almost play U16 to seal now the cut is okish i think :
then:
the problem is that on this board i feel like sealing W is not that big : W can approach from the top right and i won't get much here. with the move played i already start to claim a bit of territory on the right, easy to extend around S11. the bottom i still open so i feel i can let him add a move and still do something all in all i now realize that the laddered stone as a lot of local aji even if ladder breaker are not a factor |

This joseki is unusually good for white, I think.
This one isn't necessarily better or worse. Still looks like joseki to me.
This looks okay to me, too. I Have a pretty solid followup at 'a, too.

sorry been busy
Trigger:
not for you usually this give a big framework to B on the top, here it can be called territory. my hope is that W compensation on the left cant be called territry yet. I also hope that i can dispense with F18 at the joseki end on this board but i must think a little more on it which would allow to play on te left directly |

There was recently discussion of this joseki and why white can't cut. Now the question is: how does the donut board affect the situation? Black D16 group is suddenly quite close to the inner edge. |

I liked this last time, so I guess I still do. It takes advantage of the special properties of this inside corner Black is sealed off from the whole left side, which helps compensate for his corner, which isn't exactly solid territory but it's not exactly easy to invade, either. I'm also threatening to leak in to his side by playing like below (the interior corner really does have some interesting possibilities).

Post subject: | Re: Numsgil (3k) vs perceval (7k) - Donut Board |
looks weird but as sais i want to avoid playing f18. here is it enough to make W hane hamless:
on the other hand my hane was not possible becasue of the weird corner
taking that corner would have been natural but i was annoyed by the bad shape: (this is reinforce by the inner corner : this grop is in fact a first line group)

That feels like an awkward move for black. :/ finishes up the base for my stones, and takes at least half of the whole side as mine. I'd say the game is still pretty even, though. Well, maybe I'm up for a bit. I don't know if I'd want to play black on this board given the choice. But if you told me the game was even right now I'm not sure I'd argue. |

seems to be the biggest remaining area; I'll try to live here while keeping the san san invasion to the right feasible (the board is bigger here so it will be easier) |

Post subject: | Re: Numsgil (3k) vs perceval (7k) - Donut Board |
Approaching his stone on either side is miai so I won't do either just yet. For my move, I figure 4-4 stones like 5 point extensions. This is also a 5 point extension from black's top corner. So that's why it's here and not one or two points closer to black. It's high because I think I have better prospects of making territory along the top ceiling vs. the bottom. |

Post subject: | Re: Numsgil (3k) vs perceval (7k) - Donut Board |
lets grab some points what will he do with the thickness ? i think my bottom splitting stone is still safe |

Trigger:
Not for you: Seems okay for either side. Black sort of needs to deal with his bottom black stone now, though, because this would be great for me. A pincer and a 5 point extension from the corner:

trigger ...accepted
then:
almost played the 3 space extension then decide for the 2 space. i dont think he can pressure much my group this way |

Post subject: | Re: Numsgil (3k) vs perceval (7k) - Donut Board |
This is interesting. More peculiarity from the inner corner. I can protect the whole right side fairly easily if I'm willing to give black the bottom.
Trying to block the normal way let's him get into the side. But I get a lot of corner.
