I am wondering what extension you are talking about. Do you perhaps imagine a black shimari on the right?

There is no shimari yet. At this point, you can simply deny the shimari.

As long as Black has not made the shimari, the lower side is low and not so interesting.

Finishing the lower left shape with one move gives you time to go to other important points.

I really like this as an example of when an lower-keima is a good answer to the corner kakari on the left :)

Furthermore I like to add to Harleqins explanations, that the marked stone (in the upper diagram) now feels low, doesnt he?
I think directly playing a high move feels much better, because you dont want to take low territory, you want to build something hugh with this wall.

Here are some quick notes regarding the game and your comments:


Move 9 is also some kind of joseki. Black plays it if he doesnt like to possible white attachment at R17. Black takes much thirdline territory, but gives White much strength in return, this is completely fine.

I think the result of the lower right battle is a success for white.Therefore black shouldnt attach with move 27, but play the iron pillar (my style).

Move 40 looks kinda slow, Black still can do something, I think taking the corner at c17 feels more important now.

I would answer Black 43 with a one-space jump at k15. All in all Black 43 already doesnt feel good, there is no potential big territory in the center so black shouldnt play g13 to strengthen White and then jump in, but should jump in directly at k14 or maybe k15.

Sry for not creating some diagrams, I'm in hurry right now, maybe I'll add some later.

I don't know, if I should laugh or weep about the nonsense I've thought. You're absolutely right.

Jonas
Thank you, too. As said, I almost always collapse with Moyos. I never know how big or slow defending is, where to defend to not become over-concentrated and playing on the fourth almost always feels inferior to me, when it's not a San-Ren-Sei-formation...


Long way to Shodan, it seems ^^

Let's say that when you kicked, white responded with :w28:. Would you then go on to play the :b29: :w30: exchange?

Of course not! When you see it this way, you realize that your peep at :b29: did not destroy white's shape at all, it only made him stronger. It also emphasized your own weakness in the corner at :ec:, which is one of the problems with kicking in the first place. Before the :b29: :w30: exchange, you did not have as big of a weakness at :ec:, and you also had the option of wedging right through his shape whenever you wanted. So :b29: is both aji-keshi and a move that makes your own shape weaker.

Much appreciation for all the input.

Definitely the kick at 27 was bad, and the peep worse. I definitely like Jonas's suggestion that the iron pillar would have been a nice response.
