This page uses an experimental move navigating system. How to deal with it?
Please see /Discussion for a discussion of the system.
First, here comes the original situation again, but shown as whole board.Thanks. Just click at the link markers to go to the corresponding solution attempts. (When adding a variation, please place it in the appropriate section and/or create a new link marker, respectively.) % These blank lines are here because of some reason.

jfc: white 1 through 7 are sente here and buy white a few extra liberties at b as black must capture the white stones before playing a. After this c seems natural for white. I've played a few variations from here to conclusion and it seems like white wins.

jfc: one continuation for white. This looks promising to me ...

Charles Have tesuji gone out of style on SL?
This looks like an interesting way for White to gain some time in the corner?

Chris Hayashida: I didn't understand the result of Charles's diagram. I found something similar (in "Tesuji", oddly enough) so I added the continuation. This sets up a multi-stage ko in the corner. Is this the correct continuation?

Bill: I think that the surroundings are relevant. For instance,
Suppose that
If the Black group in the top left corner lives, Black can attack White's group on the top side.

Dave: If a White play at 7 is not a ko threat then the situation depends on external threats. If Black has a large enough external threat then White has a problem.
