Except for Black's dead group. :twisted:

Yeah, black's analysis is all well and good assuming he plays as well as white for the rest of the game. However, if he continues to make bad/slack moves (h2, c8, c4, d8, c16) at the same rate for the next 200 moves as he did for the last 20 white will win easily. However, the board is getting broken up into smaller pieces so, until some complex fighting kicks off, the mistakes will be getting smaller.

If white now jumps at f15 (c16 does make this have the e18 weakness though) and black then j16 I could see d12 dying if black over-attacks the 3 stones on the left. Of course if black plays well and white doesn't the 3 white stones could die ;-) .

Sorry for the delay in moving - I was at my Gran's 99th birthday party :razz:

The move played feels like the urgent area- black gets a lot of thickness is he blocks me in. Because of the urgency of blocking me in, I think B52 is a slight mistake.

Black 2 is likely (although I haven't predicted Joaz's moves well.) Then I am contemplating 3 as shown. Making B weak at the top would be a major success for me. My 3 stones would become strong. Moving out at a would then be a sensible ting to look at.

Note the iron pillar move played is a lot stronger than the obvious one point jump.

Black 6 is a standard tesuji in this shape, splitting white into two bits. It may just be playable for me due to the stone at K17, but creating unnecessary weaknesses cannot be a good idea (and black kosumi at j16 is sente since it threatens this sequence).

Hmmm... I had expected him to go after my lone stone up top. But he moved straight out. He's trying to kill my left side group. ( I had assumed that blocking at C16 prevented that. )

But it can get ugly really quickly:

So I'm going to play E11 first. If he wants to slide under on the left, it still looks ok for me.
It also threatens to kill the three stones with F10 if he ignores E11:

@Joaz
You showed a few bad moves for white after your 54. Do you see any good ones? What do you expect drmwc to do?
@obs
I expect f9 jump.

Yes, to show how much a difference move 54 makes. Moves that would have been good for white without it become clearly bad with it.

I think that he will run. Perhaps he will get one eye on the left first. ( But it is aji keshi ) Regardless, eye or not, he will run.

I think that F9 is the only move for white. Indeed, I think that the game would be resignable if he did not have it. Any other jump gets hacked off.

If I chase too vigourously, it gets away. The diagram below is not an exact sequence, for I haven't read all of the cuts and counter-cuts. It shows the flow that I expect over the next 5 or 10 moves.

I am currently torn between the idea of extracting K17, and going for territory up top - as expressed with one #8, and the competing idea of playing the other #8 and activating O8 to go after the weaknesses at points 'a' - believing that there is only room for one eye around 'b'.

My current guess is that I will go with the former strategy. It tends to connect two groups that he would probably like to attack.
It does not forgo opportunities for the second strategy. So the seond strategy may just be delayed a few moves.
BTW, I am not at all committed the responding to F9 with the kiema as shown above. The ogiema may hold promise too:

Interesting move by black. It's quite a good move, but it does have some slightly complicated features.


My move is nearly forced. I could contemplate a couple of alternatives:

The other one point jump above may be playable, but it seems a bit wasteful. I don't get enough compensation for the lost stone.

The hane at 1 is a bit of a vital point for attacking black's huge lower group. However, if I play it immediately the cut gives black a lot of territory and thickness. I need a good attack on black's upper group to justify this, and I don't think it's severe enough.


So the move in the game is nearly forced. Next black can contemplate a few ideas:

If black tenukis, I can patch up my group and then expand the fight. Black could conceivably tenuki 3 above:

Something like this may follow. 7 threatens a cut and an invasion. 8-10 (or something similar) protect both; but then I can take profit in sente with the marked stone - black's whole group may become weak. I have my eye on a possible cut at a for later (which doesn't work yet). If black exchanges b-c to protect this, peeping a d gives him quite bad shape. So, overall, I'm not doing too badly here.

So it may be more likely that black continues the attack e.g.:

Black 2 above is concievable. But forcing white 3 is a little painful, and it seems unlikely the white group is in trouble.

So maybe black will just press:

This sequence is likely. Pusching so much from behind is a bit painful for me, but it makes my group secure and I have some aji. Now I would expect black to somewhere at the top. I will patch my group at the top with 9.

It is very dangerous for Black to tenuki 9. If he does, his whole group could struggle. So next this is likely:

Black 3 has the advantage of preventing the cut at a become exciting. However, white gains an endgame move at the marked stone (after an initial atari.) SO then I will move out with my single stone. (So maybe black should just play at b. I haven't given a digram for this. Black would potentially be around 5 points better of than in the estimate below.)

I am behind here. However, I'm not too far behind. Rough estimate:
Black:
15 points lower right
20 points upper right
10 points lower left (assuming I get a in at an appriopriate point, and the final diagram follows).
10 points upper left:
Total: 55 points:

White:
15 points lower right
10 points upper left
15 points lower left
10 points eight hand side.
Total: 50 points.

Some elements of this count are optimistic - I have taken upper range estimates for white and lower for black. However, it does serve to demonstrate that Joaz will need to be quite sharp in the late middlegame and early endgame to maintain his lead.

Joaz's :b2: seems submissive too, this 2 could put white in rather a spot of bother, hence white's push.

His 9th rank wall faces my 5th rank wall. I suspect that the area in between will become mostly dame. But my growing 10th rank wall faces the biggest open area of the board. This can't be bad for me.

He can push the cart as far as far as he wishes. I'll be an accomodating passenger. As mentioned before, one of my goals is to neutralize the influence of his right side group.

My original intention was to play at a next. This is quite thick and relaxed. However, it may be aji keshi. For example:

There is some possibility that more energitv play may become possible. The move shown seems to be a mistake at the moment, since 6 swallow it up. However, note that I have a lot of possible cuts everywhere near my dead stone, some of which can be become active quite easily. So if I can strengthen my centre group a bit, it may become possible. So I think paying at a in the earlier diagram is aji keshi, and I will probably move out at b immeidately.

If the a -b excahnge does not happen, I may be able to engineer a cut. 8 at c prevents this, so again this is distant aji rather than a pressing aim.

The contest right now is who can tenuki to the top side first without leaving bad aji at the center/bottom.

I could play there now. But I want to get one nice shape move in at G7. It feels like the vital point. It does four things:

1) It threatens to cut him off - and possibly kill - at 'a'. I believe that makes it sente.
2) It spoils any eye shape of the three circled stones, forcing him to live by eventually connecting, thus ensuring that any play of mine around 'b' is a serious sente move.

3) It partially patches the weakness at H5. Currently if he pushes through with :w1:, I block with :b2:, he protects with :w3:, then I would have two weak spots at 'c' and 'd' with only one move to cover both. Now 'c' is covered in advance, and in sente.

Next, I'll probably play up top. ( Although I must admit that the residual kyu player in the back of my brain is whispering: "You could get more territory with B12!". This is countered by the bloodthirsty reptilian core muttering "Kill him! Attack with M8!" )
