In person, round 4 of the US open! I didn't get the last few moves recorded because I was in overtime, but the result was: |

Interesting game, thanks for posting it. Is move 16 a new wrinkle in this joseki or a mistake? I like the B result up to move 23, but I would be interested in hearing other opinions. After W got to play first on the left and top sides, the game looks fairly even to me. It is hard to be too impressed by the B center given the cut weakness at F14. I think I would have played W move 34 at H15 or J16 to try to emphasize the cut and to make the B center over-concentrated. The later exchange of L15 for K14 is the same idea and was a bit submissive for B. W move 46 is grand, and is sort of the focal point of two moyos, but I am not sure it is really better than completing the joseki in the lower right corner. Again I would be interested in other opinions. In the lower right corner, the B hane at move 63 started a difficult fight. Was this really necessary? Extending to R7 would give B a simple and good result. This is a point in the game where I would stop and count the score before making a decision. Move 73 allowed W to get the beautiful jump to M7, definitely the focal point between two moyos. Maybe B should hane and connect at Q2 instead? This would protect the cut at N3 and threaten to take the corner at R4, but if W defended the corner, B could jump to M7 himself. The solid connection at move 73 left B some corner aji, but in the sequence starting at move 97, B made some large mistakes. At moves 101 and 103, B had opportunities to start a ko. Not quite a flower-viewing ko, but very large. Once the corner is dead, B should at least play Q2 to force W to fill in all the liberties. This would earn B something like 9 points in sente compared to the actual game result. |

Move 16 was almost certainly a mistake! I didn't know that line of the joseki. |

@Daniel: An interesting noseki.  But how would you have replied if Jedo had played 21 at F14? He then seems to have threats of G17 and E13.@Jedo: You seem to have had numerous opportunities to play P2 in sente, which was worth about 8 or 9 pts - enough to win. EDIT: I see that Mitsun suggested Q2 with the same result, though I still like P2 because of less negative aji. |

I would have figured something out.
