GokyoShumyoSection7Problem7/Attempts

[Diagram]

Black to move

[Diagram]

Continuation, not very good for Black.

(attempt by tapir)

JoelR: This connects, but white saves the two stones. What if black starts with B5?

[Diagram]

Hane and wedge

Dieter: thanks Joel for challenging the attempt, rewakening my uncomfortable feeling that the solution would involve a dumpling shape. Then I saw this hane and wedge, fitting the overall theme of this part of the series: wedging into the one space jump

Tapir: What's wrong with a white dumpling shape, when it is Black to play? As Black I would prefer an eyeless white dumpling over capturing two more stones but giving a ponnuki. (I recognize in my attempt White captures the two stones with a dumpling shape, but a real eye.)

A half-truth with tewari (B7-W8 can't be good, although W4 is ridiculous too.)

Hane and wedge: var (B11 at a)

What I meant with the dumpling shape

Dieter: I was thinking of this B4, but indeed it is unlikely Black will not respond to W1. But the real indication something was wrong with the attempt you posted (and I would have posted if you had not) is the fact that black+circle is not used.

tapir: It is a little special to infer the solution from things like the stone at black+circle. However, in fact the first attempt leads to a "big ponnuki" (see diagram: continuation) which can't be worse for White than the standard ponnuki in the hane and wedge diagram, especially when Black territory is smaller too. And both sides looks quite dango-esque with the 2x2 squares. As often the problem is that I stop reading too early. Joels move simply doesn't work, I believe.

[Diagram]

Dumpling! (B6 at black+circle, W7 at black+square)

Of course it is White who becomes really dango!
