Makes it a little easier to live... and doesn't hurt my other stones too badly now they are connected enough. I think.

I find this truth to be self evident - that I must block.

The marked black group still have no eye space, there is a peep and a cutting point. So I must make sure black cannot connect underneath to the corner.

The way I block is the simplest one, and puts most pressure in the corner. I'll still have a couple of forcing moves against the corner for later.

The move black actually made is better than the one I was considering earlier, as black has sente. Good that black forced me to cover the cutting point before playing here.

I wear the black for the poor and the beaten down,
Livin' in the hopeless, hungry side of town,
I wear it for the prisoner who has long paid for his crime,
But is there because he's a victim of the times.

Now black has to defend, from a or b, if black wants to live in the corner. But - it is only a sente move. What can black do then?

But why would black play here? There is no threat to white - that would just be a reverse sente move for black. Big - yes, but urgent? No.

As for the health of the white group:

If things get tough, white has the option of starting to make an eye on the side with a and the option to run to the centre, while threatening the marked black stones, with something around b.

So I think what I should do is strengthen the group on the middle, while attacking the weak black group:

The cut at a is such that black needs to think about now. And what can white do with the wall? It is time to think about the lower left corner. What to do with it. I still have no idea about that, but having strength around with sente does not hurt.

As planned.

My idea is that the cut at a and continuing to keep black separated with b are good enough for the white group to survive. So I want to keep pressure on the black running group, building a wall while doing that.

Wow, sorry, I've been distracted.

Spied a little thing and I followed her all night
In a funky fine Levis and her sweater's kind of tight
She had a west coast strut that was as sweet as molasses
But what really knocked me out was her cheap sunglasses
Oh yeah, oh yeah, oh yeah
---- ZZ Top, Cheap Sunglasses (cause its what is spinnin at the moment!)

Basically, I am just trying to stay "ahead" of white here so I don't get surrounded and day-ed.

The problem with this, of course, is white is building up something that can help him invade the left side. But, I don't see how to deal with both of my problems at once. The reason I am not panicking is because white's top is vulnerable, and black has moves against white's bottom right group too.

But this stage of the game is clearly benefiting white.

The main thing to do now is to keep the black groups separated - to push between them. It makes the running black group weak, and might give still some profit.

It keeps the black groups separated. 3 is a forcing move, strengthening the white wall.

So the last question: should I force first?

Just a quick move...

Yes, white can continue to peep, poke, prod, and generally make life miserable for this group...

OK. So I want to reinforce the white colon. It makes it more difficult for black to turn left when fleeing. Black is very likely to answer.

So what next? As I told before, it is crucial to keep black separated:

As expected white peeps.

Now to see if the trigger is expecting me to go here.

He was. He can't cut yet so this is safe. If white does cut I will go to Q8 with the aim of cutting off the white side stones for 16 more points.

Something like this would give black and white approximately the same amount of points. But it is easy to reduce for black by playing somewhere like at a. So I decided not to.

The concern about the chosen line is the thickness black gets against the top white group - so I need to use the sente to attack the black group on the top to strengthen the white group.

Just an additional comment, not found in my previous post.

I just noticed a nice end-game sequence, depending on the weakness of the connection between the black groups:

There are some variations, but you get the idea...

The question is just whether to play it now or later :)

The marked stone isn't important to me, but my "jim" group and my 3 to right are. "Protecting" the marked stone at either of the spots marked 'a' or 'b' doesn't seem good. In fact, 'b' just gives white the ability to continue to mess with me. I looked at both points 'x' and 'y', and I think they are both okay. 'x' stretches me a little further so I'm going with that idea.

What if white cuts...

It will be interesting to see what white thinks is important next. White still has sente. The cut at 'x' is interesting to consider. I think If white tries that immediately I will turn my attention to the top group, and then see what the best course of action is to handle that cut.

My opponent made a multipurpose move. First, it seems like a really good move. It threatens my group on the upper side, protects the cut and connects the black groups together.

On a closer look, I am not sure it achieves its goals so well.

My intention is to play 1, as it ensures that my group at the top will get out. Black has two main options: a and b, to protect. If tenuki, black will suffer a big loss here when white c.
