This page needs wiki master editing.


I ran into this on the first pages when I started reading Basic Techniques of Go. It kept me awake last night.

[Diagram]

Joseki from the book (dia. 1)

[Diagram]

My variation (dia. 2)

I played variations on a goban, and this is what kept me awake late


Only reasonable continuation for white I could find was at a.

Any thoughts?

unkx80: My answers here:

[Diagram]

Black split (dia. 3)

I think Black has no good answer after W1, W3, W5. If B6 saves the two stones, then W7 makes Black a split shape.

[Diagram]

Black corner gone (dia. 4)

If B6 cuts, then Black's corner is gone after W7. (Black can continue at a, but this would be a two-step ko that favours White and heavy for Black.)


Sorry, been busy..

[Diagram]

Black makes both extensions work? (dia. 5)

Although the black shape is split, I don't feel it's bad. As far as I can read, white gets only a couple of kikashi to make black lose the corner, but white gets only one eye. The only option for white after this is to run into the center from a tight position. Is stealing the corner worth it, even if white does live?
As for diagram 4, I really don't like the way it looks for black.

And as for diagram 2, I really don't for the continuation, but it feels like my kind of move. :)
