White's play is a study in what not to do. IMO, White has fallen nearly a stone behind.

Hi tentano,
Hmm, :white: (a) is the only move here, but you discarded it as bad. (This is not so good.)
At the same time, you also consider your own analysis could be wrong even past 1 move. (This is better.)

From my experience, and I know of at least two other friends -- all around the range (SDK...1dan) in Go --
at some point, we all had the same epiphany: "I don't know anything!" (in this case, about Go.)
It's a brilliant feeling. It frees you greatly.

This moment is not so easy to come by, from my experience (in Go, and in a few other areas).
For one of the friends mentioned above, he had been taking pro lessons for about 1 year before he had the moment. (He was about 2k-1k level before he started pro lessons.)
For me, in Go, it happened a little sooner.
For me, in another field, this eureka moment happened not just once, but many times, over the course of many years.
My most recent "I don't know anything" moment (in this other field) happened after 25 years of study. :)

I hope at some point, you also experience this moment.

In the first diagram, I think white is forced to live miserably while squeezed between the corner and a black wall which projects influence everywhere.

In the second, I think white will end up eyeless, fleeing up, while black gets to consolidate a lot of territory.

In the third, I think white will shut off some of black and project influence to the center.

I can't think of anything which really invalidates my intended plan, so I'll just have to follow it and see if my opponent can do it for me.

I'm sure this is a mistake, but my goal isn't really to kill yet. I want to see how this goes. It could become a goal, but it's not as of now. My only goal now is to profit from his weak group.

Hm.

Not the expected response.

I half-heartedly plan the following, but it looks so nice for me that I expect it doesn't go that way.

I really just want this to live in sente so I can play elsewhere.

I can't really see any clear alternatives, so I'll have to hope it goes roughly as planned.
I'm pretty sure J7 is too adventurous without first pushing at P8.

I'm not sure this result is as good as tentano thinks it is. Black is getting forth line territory everywhere, he's damaging the J4 stone, and his group is still not alive.

I think jumping to :w4: directly would have been a better idea. Exchanging this move and :w2: for :b1: and :b3: seems bad for white. It may strengthen him some, but it strengthens black much more.

I felt like :w1: was necessary to support white moving out. Somehow.

I think this directly makes it harder for black to deal with the aji of both white stones at the same time. White's also liable to become extremely heavy, so I want to play something nice and loose that tries to stay a little lighter. It has a nice followup at A as well.

As I look longer, though, I'm starting to see the virtues of starting with B. Black built a moyo, white reduced it a bit, there's still aji, let's move on. Later, white can aim at C, and something near D would be o-o-yose.

( Very little reading; lazy & tired. Also, White looks so unhappy :( . )

Black will answer 1 with 2. 3 is sente against the stones on the right, white's heavy group is no longer afraid, white hasn't out-and-out killed J4 yet. Because of 1, there's no sense of a cut at 'a'. Why are any alternatives better than this?
