This move felt pretty weird, so I had to take a break and look around.

Black simply comes too far, and I can cut:

The thing troubling me with this is that black can cut. I think I can manage, though...

Because I was worried about the cut. But I did not like that, it feels it forces black to strengthen the corner more.

OK. So we are going down this alley. I guess my opponent has his sandbag ready...

I was pondering also something starting like this...

But this allows black to squeze and secure the side in sente. So it must be dismissed.

And, as I thought before; this should still work :scratch:

This starts to look worse... I think tenuki is not an option, after all. Black gets at least a ko this way...

And yet another version: how about the order of moves?

Continuing cut first think later


The following sequence looks not so good. So there must be a something else. I'll jump out and give myself some more fighting options. Perhaps something like below will be workable in the future. Or I die. Either way, its all good.

Ah. Naturally. This did not come to my mind. As I thought in the previous move, the connection on the lower side is weakish, and depends on the lack of liberties on the black group. This move adds those liberties while threatening to weaken the white group on the left of it. I need to strengthen the white stones there while keeping the white stones on the side safe.

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

White disagrees with me, and therefore sees value in creating the black dumpling.

Obviously I'm concerned I've misread something, but in real time games I continue with my instincts, so I'm letting that happen this time too.

If I have misread and the G5 group is toast-- I will fight to retain the H7 stones, because they have value in reduction, and keep the game playable-- even though I believe white will have a reasonable lead.

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

The problem right now is the cutting point:

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:

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.

There is a cutting point (F6) that looks interesting, but doesn't lead anywhere useful because my group here doesn't have enough liberties to make it so. So, I stretch.

I am pretty much in a forced mode. Let's see how it turns out. I can't really read out all variations.

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]

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 :)

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.
