No complaints about that. Feels a bit of an unnecessary peep to be honest, especially as it removes so much of my C15 / C17 aji. White's creating a fairly thin position everywhere at the moment. This is the second corner where I've gained good points, although I sort of owe another move on the bottom left as being pressed down is a bit disappointing. The aji White has left on the left is painful too ... for example:

Making miai of "a" and "b" (and even running out at "c" is painful for White), White is just failing to make enough anywhere. It's big enough to play straight away ... I'm rather tempted to play an extension on the top or a top right corner move (or play that move I owe in the bottom left) instead of something like this though - point is, White's going to want to fix it at some point later as a somewhat slow gote move.

Some thoughts:

The right side seems slightly unimportant because of the lower right 3-3, and I'm suspicious that my K8 stone will now act more as a "white can't make a big moyo" stone - I don't need to worry about making my own moyo as much as I'd thought as White's rather generously given me the lion's share of the points so far. The lower side also seems relatively uninteresting, as I'd need to fix the lower left shape, approach the lower right corner and make a lower extension to gain any really solid profit from that area.

The left side isn't as White as White would want because of the aji left in the last post, and that leaves the top side.

Because White has started to build that first piece of what could be provisionally thought of as thickness facing across the top side, now seems a valuable time to make an extension of my own along the top. I've chosen high because I think that works best with the top right and central stones, and I've chosen the position I have because I can happily extend in either way. Either of the following continuations seem good to me:

So yeah, I'm already feeling good about this game now, which is nice within 20 moves.

Edit:

Never mind, I spoke too soon. The marked stone makes a big difference--Black can play :b4:

which otherwise would have been unreasonable.

White invasion fails.

Without the marked stone, this would happen following the moves above:

However, instead of trying to live unconditionally, can White play for a ko instead?

Next, White responds with "b" to Black's "a," although Black might be able to play :b6:

at "c" instead. In any case, even if a ko fight were to happen, the fight seems unwinnable for White at the present moment. White has one serious ko threat against the bottom-left corner, but not much beyond that. Black, meanwhile, has a few local ko threats and he is the first one to take the ko.

In other words, it's back to plan "A," which is to threaten the corner from the outside so as to obtain thickness in sente. Currently, I am trying to decide between these two moves:

Ok, time to settle with a reasonably big corner. Assuming he responds, I'm aiming at this:

If he doesn't play :w22:

to protect, I'm obviously going to go and cut.
