is after points and giving up on influence
is after influence and giving up on points
it is suttle but it is very important.
i am not sure what the optimal move is but for the reason on above his move seems wrong.

it is joseky and probably one of the correct move.

This was the variation I was talking about. It gets zero results on daily joseki's database.

Wellll, I'm a little worried now that people are commenting on my invasion. Maybe jumping out and counterpincering wound have been a better use of my 5.4 stone? I don't know.

Regardless, here we are in this game, with this line playing.

I'm just going to go ahead and settle my group, and see what white does next.

That extension is strangely narrow. Even if had really strong thickness in the lower left, it would still be too narrow. At least go TWO spaces. I have to get an extension for this group here, but taking an extension on the left side is also a very high priority for me; the little white wall from that pincer joseki in the lower left really requires that something is done with it relatively soon, otherwise it's a waste.

Alright, so, white made a move that doesn't immediately require answer, which means I can do a couple things. I'd like to get the b18 point sometime, and while it's sente, it's not a /lot/ of sente, even if white ignores it, I don't gain much from following it up, so I have opted for playing the largest side. I could approach this corner from either side, thanks to my earlier 3.3, but if I approach the bottom, I likely allow white to build strength up the left, limiting the effectiveness of my 4.4 stone. We'll see what white answers with. I'm hoping to see an extension on the bottom, but I can work with the pincers as well.

If anyone has any questions, feel free to ask.

I want sente. That's pretty much the only thought behind this move.

Pretty tired, not going to talk about this much. If he had played a high extension, I probably would have played a more conservative slide and extend kite joseki, but I'm trying to expand quickly.

White will probably approach the top right corner, and I'll try to use that to get a firm grasp on the right side.

If white plays along the bottom, I'll try to play up top, to reduce white's potential there.

I feel like, if the next bit is in the top right, whoever ends in stable sente will take the extension on the left side and be ahead.

I feel a little uncertain. I don't want to let that right-side formation get big.

A few ways I can go here.

All of these moves are, I think feasible. Playing the pincer, even though it plays in the midst of a 3 jump group, would be futile without solidifying the corner first. Playing the kick, forcing white to make the ideal wall to his k17 extension would be equally bad.

A and C are both a bit passive. D is a bit reckless. I could play the 1 space jump above B but that leaves invasion possibilities for later. I think the proper play is to play B, the Iron Pillar, and be ready to attack the weakness of that 3 point jump if he doesn't take a moment to solidify it. If he does, I'll go ahead and play A to finish off the corner.

I think my opponent's last move was a bit odd. I'll take this opportunity to break up the side. He's threatening M17, but I think I can manage. I still want to get an extension in on the left side, but it's not urgent enough yet.

You'll notice I did not, at all, discuss this as a possibility. This move is best played when there is no stone on the middle starpoint. It is, I think, overplay, and by simply playing the splitting move, I should be able to put pressure on both the 3 point extension, and this stone.

With any luck, I'll be able to harass this stone pretty firmly.

whee.

Not sure where I want to go next, but I feel the nobi has really hindered black. I can easily sacrifice the original approach stone. If I break up his right side without getting sealed in, which shouldn't be hard, his potential is severely limited. The usefulness of the Q10 stone, in particular, will be severely hindered.

I'm not sure if the original nobi was wrong, but the last move feels like it must be. The marked stones look very slow and inflexible to me. Q17 in particular looks quite misplaced, at the very least it would be better at R17.

In theory, this creates a family feud, but as I said before, I can sacrifice the original approach stone very easily. I didn't see very effective moves that leaned in the other direction, and sliding into the corner first would let me get sealed in, which would be very bad.

Black will have a hard time taking the corner territory without taking a bad gote or even getting sealed in himself, so he's lost a lot of potential here. The black corner stones are inefficient.

It occurs to me, I don't actually know joseki for this line... but there are a few thoughts that come to mind.

I chose this one, because if white defends at 24, this sequence leaves their group unstable, requiring more moves to try to stabilize

Some other thoughts occurred to me.

In preparation to attack the split at A, playing 1 to keep the white group running seems fun. 3 forces white to struggle for a base. The cut at B is not urgent because of the response of C, which further weakens the top.

A third idea:

Notice that the group on the right is still in the trouble, and this threatens to attack A directly.

But, it doesn't actually add pressure to the right, so it doesn't allow me to seize sente to take A.

If anyone knows the actual joseki, and I deviated from it, do let me know.

That is, if there's any sort of joseki for this situation.

Not sure what he's going for here... This should make me stronger. Yeah, he could protect the corner now (at the expense of making me strong), but that would be inconsistent with his last move.

Not sure if this is the route I'll go if he tries this. In particular, it might be better to connect solidly with for better shape, even though I'll need another move to protect the cut.

This looks even better for W:
