Mainly cause the following line isn't so scary... and I need to get out of here. (i.e. white isn't ready to cut yet)

I'm also not so concerned about the dumpling white can make out of blacks stones. It will be a cutting dumpling

I'll keep my cutting dumpling. Its so cute and frumpy.

Ok. So I got the other side of the dumpling fixed in sente.

The problem right now is the cutting point:

I can try to protect the cutting point and start running, as here:

And I'll end up in a dumpling formation with possibly fewer liberties as black (but possibly better, as white has the atari at x - but black can play there first and try to capture at a or b then ), and 1 did not help at all.

Obviously, this 1 does not work. Then, how about this:

O X . . | $$ | . . . . . . . . . . . . . . . . . . . | $$ ---------------------------------------[/go]

Here, white cuts next at x and either gets the black dumpling or escapes to the centre.

The problem with this move is that black will not answer 1, but annihilates the white centre stones first. After that, 1 will has slim chances of living. So this does not work.

So, I have to forget now the cut, and let black squeeze

After this, 5 threatens to mess up with the side. Either connecting up, or using the aji of the forcing stones below, to cut black. The problem is that the black corner is huge.

So how about just running, and returning to the side later...

Here, white should be ahead in the liberties, even with the cut. So black cannot keep white in, but instead lets white just escape, or cuts the marked white stones off.

If black plays 1-3, black should let white go, or it gets in a mess:

... but right now I am getting tired on this speculation, so I'll just move with this 1, without worrying about the cutting point yet.

I think I can free my group, or create a more interesting fight if white tries other lines of resistance. [For example,
white 2 at 3, or making a bamboo joint at black 5 instead of 2]

OK: I considered three primary options:

b does not work, I will not have enough liberties left when black cuts at c. So a and c are left. A is simple and just connects, so it is a nice move. The idea with c is that when black pushes, black hurts also himself. Namely, after c, white can try to reduce the side much more. The problem is that the connection with the lower two stones is lost:

I think the loss is too big here. So what is left is this:

And to hope that if black tries to contain white, black will also be cut and have fewer liberties left at that point.

Then there is the question of forcing moves - should I try first something like:

I guess now is not the time. But I cannot really tell. Let's see first how this turns out.

I have to take a bit more time for this one. Some reasoning is hidden here, for spectators only

We'll have my parents in law visiting us this weekend, so I'll return on this probably on Monday evening. Sorry about this.

I kind of noticed this and then forgot.

Two options:

And then trying to break out.

Neither looks good.

Seems it is time to try to play more lightly, break out and try to destroy as much as possible.

Perhaps something like 1 first and hope for a later.

... well, it seems white can live, because the cut should not be sente for black (even when white keeps also black cut), but bye bye points...

Take your time. Truth be told, I'm not quite sure what we should do with the mess we made either

Hmm.. too complicated.

I have to get out. Both these work:

The problem is that black can then secure the corner

I cannot see alternatives, though.

Of these two, I chose the slower one, diagonal connection, as I wish I can later attack the two black stones.

White runs. Based on my thoughts of the score I think its better to
simply garuntee that my bacon is safe. White can escape almost
completely with his next move, but that is okay with me. I think.

Other lines considered. First, starting with F7. I didn't like
the idea of forcing white to protect in this way...

White could still play such a sequence I suppose, but at least I
don't force it.

The idea of attacking agressively appeals to me, but my stones aren't
strong enough. The interesting fallout from this fight is I again
have some moves against whites center group. If I can cut it up
one half or the other is going to be in serious trouble. Let us see
how white wants to proceed first though.
