Turns out I can't beat a 7 dan

Post by Koroviev »

Here's a game with a 7 dan player who was no doubt going easy on me, but some interesting positions came up before I resigned so I thought I would post it for review. I'm white.

I've included comments/thoughts in the sgf. Any advice welcome! :salute:

4: As he played a facing 3-4, whoever approaches first gets an advantage so I might approach instead of taking the corner.
6: This is old joseki, not many points.
12: No, c10 would be slow. Your approach group ended up rather a liability. Maybe o3 approach to reduce severity of pincer, or choose something other than p5 jump which aims to settle fast (n3 perhaps?).
22: maybe just try to live at r3?
32: Very slow, that group is already alive, you need to come out at j9. That's about the only good thing one can say about that old joseki: it is a strong shape so you don't need to help it. But you did.
45: Game over already IMO.
97: He's ahead so doesn't need to play optimally. Also by avoiding a semedori he can save a few points.
124: Should capture, then monkey jump is your sente like normal, instead you gave him sente as he doesn't have to defend a cut at f2.

Some comments on the opening. :)

At least in traditional Japanese Go theory, I think :w12: (P3 approach) would be regarded as a bad move, inviting an attack where B is stronger and likely to profit. The wider approach (O3) suggested by other reviewers is certainly better -- it leaves room to settle on either side, so it should succeed in breaking up the lower B area without suffering a severe attack. However, I would prefer to play somewhere in the upper right corner, which is much more open. If B gets to play first in the lower right he can secure the corner, but he is not threatening to make a big moyo, so W does not need to take immediate action to prevent this.

:w20: was fine, making your group totally connected and secure with reasonably good shape. I think B was taking it a bit easy on you, resolving all the bad aji here. The resulting position is about as much as W should expect from the original P3 approach move within B sphere of influence.

:w22: (K4 attack) is dangerous but gives W fighting chances, so it is a great move in this position -- congratulations for finding it and for having the courage to play it. For :w24: the only move I would consider is H4, leaning against the strong B group to the left in order to strengthen your weak stone.

In the running fight from moves 25-32, you played on the wrong side a few times, extending from the stronger group, ignoring the weaker group. :w32: in particular must be used to save your center stones.

Your evaluation after :b45: is quite optimistic :) The game is over -- B has superior center thickness and at least 30 points more territory.

Well, he is 7 dan...I think optimism is the only weapon I have against him. :mrgreen:

Thanks for the comments, studying them now.

What struck me about playing a strong player (first time I've played someone this strength on 19x19) is how normal and pedestrian most of his moves seem...and then before I know it I am miles behind, almost before the middle game has begun.

Probably more to do with the strength differential I suppose.
