Here is my plan. Black has two obvious moves to save his single stone. Thie first is this:

If black use the diagonal move, I get a useful sente exchange at 6-7 which eliminates a lot of bad aji for my central thing. Then I attack the whole lot. I am behind, but the game is playable given it's on 4 stones.

The other move is:

This move keeps my aji worse (e.g.at a). However, I can be more vigorous in the centre and the fight may not be too unreasonable for me.

@ all: Life is busy right now, and the position is complicated. So it may be a few days before I post a move.

@Observers:

There are three posible moves here:

A) The most aggressive. If I can play the cut and hold it, I win. Unfortunately that does not happen against best defense - which my opponent would probably find.
Nonetheless, there are some variations in which I may profitably play it and sacrifice it, making eyes in the middle while he kills two or three cutting stones. If I can be assured of leaving the center with sente to start yose, I'll choose this line. ( It is a big 'if', so more reading is required )

B) The safe move, which holds everything together, and ensures that he does not get much territory on the upper side. However, it is slow, and allows him much room to for mischief on the right side of the center.

C) This strenghtens H13, and thereby aims at pushing at G13, for either a connection or an attack against F9.

These three each give the game a distinct character, and there is no going back after I have chosen. So I may take several more days to read.

All lines have one thing in common: I'm looking for an opportunity to play L8.

Feel free to take your time - after all, I spent around a month on a move recently!

My original plan was the diagram below. However, black 2 is then strong and leaves me in a bit of a bind. (I may be able to capture somehting somewhere, but it's too expensive.)

To avoid the mess above, I could contemplate this line:

Again, this looks less than inspiring.

Another move worth condiering is this:

This is similar to the game, but seems to give black a few more options (e.g. playing at a with 4 to give up some stones but take the initiative.)

This is a surprise. I thought that he had to push one more at 'a' to improve his shape.

Which means that he can't fix the cutting point at 'b' in sente.

I'm inclined to play K15 immediately.

I won't try to show all of the hundreds of lines that I have looked at in the past week.

In general, I like creating the weak spot at L16.
In particular, one of the reasons that I chose to play it is that if I later play 1 as shown below, I can either kill something or connect underneath:

If he prevents the connection with 2:

Apologies for the delay - I had a few days off to walk up hills and win a Go tournament.

My move is probably not a great surprise. I am getting a little thin with my big group, but I don't really have time to patch it up first.

I did contemplate this idea:

I can play a probe at 1. If black cuts me, I get a connection beneath which is big. However, I then need to deal with the cut at 5. I have some shape issues.

If I patch up in the centre, black has some nice aji at the top:

White loses the game here.

So I'll keep the aji at the top undefined for now - I may prefer to play from the other side to the probe shown.

My expectation is that my move is sente. It's not completely clear-cut, but answering locally is nearly forced. Assume black plays hane (extend may also be possible):

The 5-6 is pretty close to sente for me (big black bits become thin if black tenukis.) Later, the a-b exchange may be sente for me. I still need a move to patch up. There a quite a few possibilities, so I'll address the issue if we reach this far.

I also have a slightly ridiculous side plan if black hanes:

I have a cut, but it gets a bit discombobulated. Next I think I have to play at a, so black next decides his favourite attack against my central monstrosity.

I am generating some cuts of my own in the centre, so it may actually be playable. But it needs some careful reading.

As planned. The cut was too hairy. I probably need to shore up my big central thing - this is quite big and very nearly sente.

3-4 is nearly sente and quite big. (4 at provoke white b.) I think I am strong enought in the center to then probe at 5. The 6-8 replies are quite passive,so may not happen. (It would be nice if they do occur).

Next I may do my fany probe:

Capturing the stone does a lot to shore up my position, and puts pressure on the top right black group.Descent at 12 above may be an overplay - hane at 13 nearly kills.

So black may need to defend at the top right with 12.

I now get the big endgame moves on the right. I have large moves coming up at a and b.
Black's centre-top group is not 100% alive, which increases the size of the move at a.

I am behind, but if this diagram happens, I am pretty close to catching up. If I can wangel getting both a and b, I am probabaly around 10 points behind. For this stage of a 4 stone game, that is an acceptable outcome.

As planned.

I'm pretty sure black's forcing move was a mistake. It removes this cut:

As a result, my central group-string is becoming pretty strong. This in turn means that black's central group is weaker. For example,

Black seems to lack two eyes. It's unlikely to die, since it has access to the centre, but aji like this is very nice to have. It is likely to give me some profit somewhere.

Edited to add:
The lower left yose may also become entertaining for me.
