One question is whether
is sente. For example, even with
,
B can start to make eye shape quite quickly (which was one meaning of
):
$$W
Click Here To Show Diagram Code [go]$$WIn the game, B is not clearly alive yet, but it is also not clear to me
whether W can completely kill B. If I stubbornly try to kill but fail,
in the process I will have removed all bad aji for B, and may even lose sente to play
.
So let's leave B alone for now and tenuki.

Ed:
Perhaps 1 isn't sente to kill... it is still pretty big to get sealed in like this and I don't think B should allow it. Also, are you sure its not reverse sente? If B gets one then the aji those two marked stones looks really annoying for White. Also, it starts to feel Black is gaining enough strength to start something around 'a' later. I would rather take gote even to fix that:

Yes, of course I wanted
also, but I could not have both.
And no, I'm not sure about a great many things. This will be an interesting point to review afterwards.

No problem with

tenuki, W already can profit locally with

Well, that doesn't influence the group fight, and I think I'm mostly alive as it is. I'm also unsure how easily White can get sente from this sequence. I'm quite glad White chose this point to approach, I felt the high approach from the top would be more awkward somehow:

Reminds me of a couple of positions in Yilun Yang's, but maybe White's not thick enough in the top left to play this way.
Either way, if he takes the 3-3, I get sente. I'm also happy to fix the possible invasion here a bit:

Yeah, I'm desperate to play up there, but so's he I expect, so we'll see who gets it first:
$$Wm44
Click Here To Show Diagram Code [go]$$Wm44
I'm expecting something like this. I sort of want to kick first, but I don't think he'll respond to it, I think he'll switch directions, so I'll just try to claim points. Either way the cutting aji at "a" is increasing, and the usefulness of his thickness is decreasing.
