Playing at bottom, e.g. K4 is a bit tricky due to the forcing move M3 and finally seems to strengthen white's center more quickly than necessary. Therefore I keep trying to strengten my groups along both sides. It seems that O7 is more solid than P7.

I don't think I can tenuki, so I think its best to jum into the center while making a 3 dimentional shape.

Fixing my shape (now, there seems no more cut possible at right side), putting some latent pressure on center and threatening a big moyo in upper right could not be totally wrong. The bottom side has become completely uninteresting. With k4 I could secure around 15 points there while handing over all the influence on the remaining board to white.

I think my center group is strong enough to take a big point, and this one is HUGE. If I am incredibly lucky, I might even get to split him down the middle and attack the wall on the left.

I would have liked to play myself at the place of :w32: for sure. However after :w30: I had the feeling that I have to reinforce the connection between my N4 group and top side. Because white could disturb with forcing moves like M3 it seems not too easy to live at the bottom, if this group gets separated. But maybe I was too pessimistic here(?). In any case this would be interesting to further analyze.

Regarding the game move - if white replies at left side I am planning to play some "capping" move on the center and see what happens. My left side group has better shape than my right side group, in an emergency I could settle it at the bottom by playing K4. If my plan works I'll get some strength in the center radiating towards top side.

He seems to want to capture the middle group on a huge scale. I thought about tenuki, but it seems a little dangerous. My shape here is light and three-dimensional, so it should be fine. I think it can live inside without too much trouble if he tries to swallow it.

While white still has some options, I think that black would be happy if he were able to get lots of outside forcing moves in exchange for making white live small in sente, and then proceeding to consolidate a huge moyo on the upper right into territory. Black could have the same potential as before, and all white got was a 2-point living group in what's now a dame area.

I'm not really glad with the opening. The only thing w has to do is to stay alive in center, then at least my left side is fairly ineffective. But the show must go on...

Since he keeps trying to build the center, I guess I will just make sure I eat it all up. The only are of the board where Black has large potential is the right hand side, so I jumped in that direction.

B played a little soft here I think. I was expecting an attack somewhere like "a" which seems much more severe. I considered taking "a" myself, but at second thought it seemed small and passive, and it only guarantees one eye.

I next considered the attachment I played. The fight is very favorable for W if Black hanes at "a" so I expect he will hane above. I didn't wan't the fighting to result in a large black right side, so I plan on jumping afterwards. I might have gone straight for the jump and sipped the attachment, but I think the attachment give W more options, and takes some away from black. Peeping at "b" for example no longer looks as good for B.

Why not...? One small crosscheck in case if white crosscuts: H11 J9 K10 H9 and neither the ladder at J12 or the net at J12+L12 works.

There are many different choices, here, e.g.
- Start something messy in the center, but this feels insecure and badly prepared.
- Protect right side at O12, but this somehow has a "pushing from behind" feeling. Further, the "sixth line territory" would be still pretty open for invasion.
