Life In 19x19

Actually, I think this is maybe better than extending... nice and thick, and now I can push through and keep him eyeless...

This one feels like a no-brainer ... need to start thinking carefully about how to best take advantage of this soon though... I don't want to force Black to eat up my left side points, and I don't want this group to come under attack either

My shape is terrible, but his is pretty bad also.

unfortunately I'm weak here, so it gives him a better advantage.

Again, a no-brainer, but if he extends, I need to decide what to do more carefully:

The area marked "a" is potentially useful territory for him, and if I keep pushing I can invade it quite happily. Of course, to do so will sacrifice points around "b". On top of that, the group I'm currently pushing with is weak, and although I can settle it with "c", I don't want to kill my two stones above "c" without a fight, so settling by moving into the area at "a" may be useful to prevent me losing those stones. "c" is still just big in its own right though, and I have other ways of making a move against him later with a move like "d". However, on a purely points basis, things are looking really quite good for me with that corner exchange, and I really need to avoid upping the stakes too far. I could have a mutual disconnection thing going on if I ignore his next extension:

But as and the marked White stone are both rather endangered, this is a really risky sort of idea to try. @ may well be good enough, as it creates some serious issues in his position:

This is probably my current plan, as a wedge leads to a tricky position for both of us, but as his big dragon has no eyes, I may be able to get away with playing the atari from the top:

The problem is now I'm thin everywhere, and even though he's got issues, I think I have more. Playing the atari on the other side is safe:

If I now kill his lower dragon, this is obviously game winning for me, but the outcome of this shape is far from clear in my eyes. Currently, this is my best plan I think, but it's really too tricky reading-wise for me to have any confidence in it.

This is the sequence I expect

I misread the net before playing my last move. this is essentially a one way street he has to play the other nets fail. I think if he plays this I will resign.

Interestingly, and for observers that can see I'm both making broken shape and toothpaste squeezing. My logic is that it keeps him weak enough that he's forced to toothpaste squeeze me back into his territory, with greater losses for him than I'm going to suffer on the left side - that's the theory anyway.

What is toothpaste squeeze?

It's discussed here: http://senseis.xmp.net/?SqueezingOutTheToothpaste

As planned ...

White might have overstretched himself slightly, as there is a remaining weakness in white's position.

It's not overly serious if white doesn't try to cut off, but it does mean that white's left side is a bit smaller than it looks.
