He gets sente, but I'm glad to have gotten the marked stone in:

I'm taking a bit of a risk here, not solidly killing O3, and leaving some aji in the top left. However, this is such a huge area of the board that I feel like I probably ought to take it. Obviously it works with my wall to the right, if my wall isn't punished too harshly. I imagine that Kirby will either extend up the left to continue taking massive amounts of points, or he will shoulder hit M3 as a reduction, or he will try to escape with O3. If he plays on the left, I will work on building the bottom. If he shoulder hits, I will probably try to use it to remove the aji of O3. If he activates O3, I will try to chase and keep him weak, ideally while claiming points on bottom.

actually, this common shape is usually considered strong enough so that you don't have to immediately remove black stone's aji, so i wouldn't worry about white's wall very much

open comment: (I'm fairly certain this variation can't appear anymore o.o)

I'm interested to see White's next move.

Click Here To Show Diagram Code [go]$$Bcm41 Prisoner Count: B-0 W-0Hey, that's the point <I> wanted...~
Here, I feel like Bill would tell me that if a wall is truly thick, it can ignore small pressures against it. As a result, I'm going to try to take sente to press back. If black ataris my stone at C18, I can atari at D12, and be glad of it. If he responds, then this move was good sente (seemingly not burning too worthy of aji), and I can look at other areas. I'm considering either a shoulder hit on the left low stone or a move at one of the several boudaries of frameworks. F7 or O13 look particularly juicy, as they're glancing at some fairly reasonable invasions. For example, after O13, I have R16, which I can follow up with R13. That'll need some more reading
(as always), but it looks like it might have potential.

On a conference call, so I can't comment too fully. However, I just like this too well to pass on. I have influence above and below, and this gives me some options on the left. Or rather, it gives Kirby some options about what to give me. Either he tries to fight it and makes his cutting stones heavy (in which case I'll try to get some territory from chasing), he can wall me out of the left, in which case I may get to expand with something like E7/F7, or he can build the bottom left, in which case I split and reduce the left side. I expect C11 next, as it threatens to cut off my stones, saving his cutting stones, but I'm willing to leave that aji and connect afterwards, in order to get 48 where it is. 48 gets me a bit further south, helping me build the wall I want. I kind of feel like my opponent should have kept simple, instead of taking the double-hane.
