I think this was a terrible game played by me. Originally, I debated about which opening to use, but I settled on the Sanrensei figuring it was my best chance to beat a 5d, but alas it just wasn't meant to be. I just made all kinds of mistakes. I suppose that's to be expected, though. Maybe next month.  |

well, your opening was good, he made a huge mistake in the bottom right, (he underestimated you a bit I think, or maybe he just got lured in by the aji there, I nearly did too) Afterwards though, you didn't consolidate your advantage, and kept trying to fight. Your goal with L17 was to settle as quickly as possible so you could use your massive thickness in the bottom right to build moyo on the bottom (by approaching the bottom left), but you got a little cut-crazy, and ended up dying, and then didn't factor in the remaining aji in the bottom right corner. You scored a win in the bottom right, you just need to know what to do with that victory when you get it. |

Your response to R10 was fine, you built a massive wall, that wasn't the issue. K15 was a problem, you were attaching to his stones, and ended up making both the top and the right weak. J16 instead of K15 made more sense, your goal was not to capture those 2 stones directly (which you had too much bad aji to do) but rather to just move out on both sides and let him struggle a bit. Next at Move #68 You need to stop here and ask, "can I net these somehow? if we both keep running out, will I ever catch him?" If the answer is no (and it is no in this case) then you shouldn't keep on pushing, that is aji to be used for later, you just need to leave it alone for now. If he spends another move solidifying it, great, but if you just struggle, he becomes many times stronger. By move 82, you've lost any and all power in the center and most all your aji with your dead stones. Now, that being said, he still makes another mistake in the upper left (proper play when you jump into the corner like that would be to exploit the H13 weakness.) And so before you make your catastrophic mistake in the bottom right, you actually make excellent use of your stones. Really, this came down to one move. N10, if you had just played N8, you would have been fine, but you didn't watch your aji, a bamboo joint is just asking for shortage of liberties plays. |

Up to move 42 you have outplayed a 5D. I'd be proud to have attained that position myself.

I suppose studying the Kobayashi fuseki like I have is paying off! I'm not strong enough to really question a 5d, but I think  should probably be at R2.Now if only I could play a whole game as well as I played the first 42 moves. Knowing joseki sequences really helped me here, in my opinion. |

They were really beneficial. I guess some things are just hard for me to visualize. Like when you said I pushed too much. I think I've definitely improved in the fuseki department, but my overall direction of play probably needs quite a bit of work. As I said, after move 42 I sort of lost my sense of direction, and I wasn't entirely sure how to proceed in the game. |

However, it so happened that the stone at q10 meant the refutation of r2 no longer worked, so it was a mistake of white's to play the joseki move at r8. But with q10 in place, this clamp at p8 doesn't work as r9 becomes atari when it wouldn't otherwise be: The reason r8 is usually a good move is due to the following sequence: After white lives in the corner, black now has 2 problems at a and b and can only fix one (which one he chooses depends on the whole board position). If white doesn't play r8 then the sequence goes as below. After white defends at a, black can fix at b. Using tewari, if white played r8 now, black would of course just capture at r9. However, by playing it earlier white makes black answer r8 at q7 which is obviously rather stupid. So if you read that the clamp didn't work, then congratulations  . However, my suspicion is that you were lucky your opponent also knew joseki sequences and played them without bothering to look at the stones actually on the board  .P.S. his double approach at r6 was an overplay and I expect he did it because of your lower rank; the most severe answer is to play 3-3 yourself and then push and cut when he covers your corner. White then has 2 weak groups and the fight is good for black (so long as you know how to not die in the corner: the straight J group is alive with an extra hane). |
