Thanks to Victor and quantumf for the comments. Yeah, seeing n10 on the board again makes it even more obvious that it's essentially game over for white if I get that. It's a bad habit of mine to think I can try to get in some not-really-sente move before the important one. Given how good n10 is, I think his p8 should perhaps take a liberty at n8, even if it does mean he doesn't get to p8 kikashi first. Would I then continue at n10 anyway, or m10, or tenuki? About c7 for 119, whilst that might be the move that leads to the largest win, I thought as I was ahead I shouldn't give white a chance to make a complex fight as he's better at them than me. I planned to hassle the centre group in sente first to make sure the e12 cut wouldn't put the g11 group in danger (of course c9 is in danger too so black should be able to handle things fine, but I am good at dying in byo yomi) and then think about c9, though in the end his peep made me reinforce at k9 which was not quite as sente as I hoped so he got to fix with e6. I see he agrees black p19 is not a good plan, just s9, and then d8 is nice indeed. t14 for 184 is dangerous though: I s12 in sente and then t4 throw in and he can't answer or t7 kills the big group (as n14 falisfies that eye and I don't see a way for him to turn that half eye into a real eye in sente, did I miss one?). Good point about c10, I did think about that at some point in the sequence but missed it in the blind panic at that point. |

It is worth noting that here is not a recent innovation. The Suzuki-Kitani Small Joseki Dictionary devotes 9 variations to it, so it goes back at least 50 years. |

Well, I did check GoGoD before posting and there are about half a dozen occurrences before the 1990s, and most of those aren't in open play, and almost a thousand since. So maybe it was in a joseki dictionary, but it didn't pass the test of being used much in actual play. |

So maybe it was in a joseki dictionary, but it didn't pass the test of being used much in actual play. Well, a couple of variations were said to be equal exchanges, but none were called joseki or common patterns. So it was certainly the Koreans who developed it in recent times. (But I played it a few times myself in the 1970s. ) I suppose that there are rather more variations in Suzuki's great work, the Igo Daijiten. It just goes to show the thoroughness of Suzuki and his researchers. |
