Life In 19x19

For observers:

I don't understand white's latest move.

My penultimate move was a compromise, with the primary goal of strengthening my wall. After his play at 3-3 and my descent at the 3-4, my wall is even stronger.

I'd expect him to stay away from it.

I was expecting an approach to the remaining corner with something like 'a', or a play on the remaining open side with 'b'.

It seems that my opponent has no respect for walls.

I must change that. :rambo:

His next will almost certainly be a supporting move for his previous. When he does that, I intend to push him toward the wall.

===========================================================

Actually, I suspect that my oponent does have proper respect for walls. He may be trying to use his over on the right.

I think that his long term plan is to build strength on the left - even if it means conceding some territory there to me, and then try to push my upper right group into a fight in the middle.

Something like this:

So the latest addition to my list of goals is to somehow neutralize his strength on the right. :twisted:

Did you consider d11 jump?

Briefly. I'm probably not really strong enough to distinguish between it and the move I played. With that caveat in mind, my thoughts were:

Black 42 here feels sort of natural. Then 43 as shown is good shape, but very slow. Black get a lot of territory.

As played:

42 as here feels a bit loose - it's quite far from my move. I can now bodge my group in sente and get first move at the top. The pushing on top moves with 43, 45 and 46 are more effective with the move played than with the jump. They add to my vague moyo-y plans.

Alternatively, for black:

Black 42 here give me more to aim at than in the first diagram - if my group is strong, it's too close to thickness.

To observers (particularly Uberdude ):

I'm feeling much better about this game in the last two moves. Three moves ago, I made a compromise move - my second of the game :oops:

- in return for a wall that I hoped to be able to use.

Much to my surprise, my opponent played closer to the wall than he had to. ( Or at least closer than I thought that he had to. ) He then followed this up by making himself heavy.
I'm not going to say that he has made a bad decision with these last two moves, but they do have some theoretical disadvatage. Presumably he sees some advantage that I don't.

Regardless, the theory is simple for me: I should push his heavy eyeless stones toward my wall, and make territory while attacking. ( Note to Uberdude, who posted while I was writing this: while killing would be preferred, I don't think that my opponent will be that cooperative. Besides, attacking is good enough. ) He will run through the center to what is ultimately mostly dame, while I will get a picket line outlining territory up top.

I'm thinking of something like this:

drmwc has already indicated that he will play :w43:

, which is usual. I hope that Joaz continues with :b44:

. His aim should be to come out of the fight with sente and take the last big point on the top side.

After :b44:

in this diagram I think that White has caught up by about 2 stones. Recent culprits are the :bc:

stones. The sacrifice was an overall loss and the stones on the left side made Black overconcentrated. There is also a certain heaviness to Black's play.

This was my suggestion for :b28:

. I expect that it is objectively flawed, that Black should play kikashi against the White group on the bottom side in order to build up thickness before extending on the left side.

But what happened in the game? Black made plays against the White group, but then worried about his wall. That is why he made the short extension, and why he blocked at C-04. Instead of making thickness, he made a heavy wall in his own mind, too weak to leave alone, too important to lose.

was not my sealed move, but now I see that it is a very practical play giving four stones. But after that I would continue with :w41:

and

. This is lighter than drmwc's continuation, but it seems that he admits to having a somewhat heavy style. We shall see how well Joaz can attack, assuming that he does.

After Joaz's post I can now project play to go this way. Note that instead of driving the White stones towards the Black wall, Black is driving them towards the White position on the right side, where they may be used to make a moyo. In any event, the result is a reduction of Black's influence instead of using it to attack. That is why, IMO, :b44:

should top the tree at 45.

However, Black is building a moyo himself, in effect transfering the influence of his wall to the top side. This kind of sideways attack is not an unusual handicap strategy.

Still, isn't :w45:

in this diagram a beautiful move?

Hi Bill,

Instead of :b44:

trying to cap and split W:

I was supposed to spend the weekend scuba diving with seals in Scotland, but Hurricane Bertha has blown it out. :sad:

Joaz' move is a reasonable idea. My reply is multi-prurpose:
1) Indirectly strengthen my group
2) Stop Black connecting, which would be a lot of territory for him
3) Give me some nice pushes later on to make Black more over-concentrated and increase my thickness.

For example, suppose black plays as shown:

44 here strneghtens black and tries to take some terrtiroy whilst attacking. So it's not a ridiculous move. But then I can bodge up my grooup in sente and take the big point at the top.

I think this is a reasonably sound approach to ultilising my thickness - ignoring it and using it to justify that my group on the other side of the board is strong.

I have a little aji left in the diagram too:

This sequence mya become viable. At the moment, Black doesn't need to answer 1 at 2, so it doesn't yet work. But it may work eventually. Joaz can also side-step this issue by playing slightly more crudely earlier:

The 46-47 exchange isn't obviously good for black (although it may not be bad). I ssem to pick up an endgame move at a, although the cut at b is potential niggle. Which means maybe I shouldn't play the knight's move, I should push:

This line in certainly possible. I still get endgame at a, and the push at b mighjt become fun. cutting at c could also be entertaining. I don't think my group is weak.
