I cannot play the sequence above if the 5-a exchange has been played. Black 5 is not really sente at the moment.

For observers
Hmmm...he plays the fighting move at C18 instead of the more teritorial B18. :o
And since he is already behind in territory, this move suggests that he has given up on competing directly for territory. It consequently implies that he is assuming that his best winning strategy is to kill something.

Now this may be old news for you observers, but it is the first solid evidence that I have of his intentions.

It is not an unreasonable plan. I have two groups that are right on the edge of getting killed.

My current assement is that my left side group can be reduced to zero points as it struggles to live, barely succeeding with seki. I'm still about 10 or 15 points ahead then.

If it does live, I can tenuki with H8.

That makes miai of the two shaded areas. If he has to defend at G16, I can play the other spot ( probably N10 ) which then makes miai of the two circled spots, threatening to kill two of his groups. Then, even if he is succesful at living with both, I'm alive everywhere, and I go into yose with sente.

It looks good for me...IF my left side group can live.

I must take some time to read this carefully.

I still can't see how he can kill my left side group.

For observers:
The more I look at this position, the more I tend toward the conclusion that this game will be over within ten moves. My middle group can connect or make a second eye. If he kills my left side group, I lose. If not, I'm ahead by 10 to 20 points, or more.

He can reduce my left side group substantially. But to do so, he ends in gote, and then I still go into yose with sente and at least 10 point lead.

I was tempted just to connect my bits. However, that seems to leave me behind. So then I looked at attacks against the top left black groups. These don't work yet (See diagram below).

The move played seems to activate these attacks. It also indirectly strengthens me and makes separating white in the centre more severe.

However, it may well be an overplay. But it feels like an aggressive move is best.

To observers:
Ouch!
IIRC, part of my defense was a timely play at C11, which threatened to get another eye. It has been a month or so since I read this out, so I don't remember the details. But I do remember that I die if I don't have that threat. So I think that I have to let him invade.

He can invade some of my territory on the left. But he has to keep sente, and/or come back and patch up on the right in gote. If 96 goes unanswered, P7 starts to look interesting. And while he defends against that, making sure that N5 has two eyes, I'm building strength to go after L15.

All the while, the end of the game gets closer, and my two big right side corners loom large on that horizon.

Black lives here, which means I am in trouble in the centre.

With the game move, black blocking is big, but I have a nice empty triangle reply:

The 2-3 exchange removes a connection for me. Then 4 is big, but 6 threatend the connection again. Black gets very thin if he stops the connection - fixing the centre is prudent. Then 7 links up with ko (unconditionally if I can get a forcing move in at a first.

I contemplated moving in the centre instead of linking, but that's quite hairy as well.

For observers:
If I get the cut at G16, he has two iffy groups. I assume that he made the indirect connection in an attempt to protect his eye space.

He threatens the obvious H18, connecting all of his groups and making territory. So my play is forced.

For observers:
The trigger move secures life permanently for my group, and gets enough territory to put him back in the position such that he must kill something to win.

My center group has five possibilities for life:

1) Make a connection southward
2) Connect at E18
3) Connect to M17
4) Get a second eye on the upper side while threatening #2 and #3.
5) Get a second eye at N9

He can't stop them all, so I'm looking good here.

3 cm visibility? That would actually not be too bad compared to some dives I've done...I'm jumping into a muddy puddle this weekend.

Sometimes, though, it all makes sense:

Anyway, trigger accepted. My move will follow.

Maybe Joaz will descend next. That threatens a connection. However, I'll play in the centre to heat up the position:

I get to attack the remaining half group. I'm not completely alive myself, but the fight is at least plausible.

But if Joaz connects in the centre, I need to play ko to link my bits:

However, I may need to keep this in reserve. Joaz can play normal moves as ko threats, which could leave me well behind.

So now I am coming round to cutting in the centre with my next move. e.g.

At this point, the position is quite hot. My group isn't alive, but Joaz has 2 groups without eyes. I may have miai of the marked moves next.

I get slightly bad shape with the particular cut shown. The marked black stone being sente is annoying as it gains eye shape. So maybe I can start with 3 at 5 above.

It's complex, so I will give the matter some thought.

BUMP
Either he did get stuck in some British mud puddle, or he realized that he cannot kill my center group.
I'm not sure which is worse. :lol:
