Well, that again feels aji-keshi for Black - I suppose he doesn't need to worry about wasting ko threats with the top left as it is.

So, I've deviated from my previous analysis because he pushed first. Why? Because he's taken away his own liberties, and I think the Black group's in real danger now if he doesn't take another move to protect. I think it's gone from a really big reverse sente move to virtually double sente, so not only is it relatively very important to me, it's a lot more dangerous for him to treat it as gote.

What's more, even if he protects at G3, I can cut straight away at G4, so everything looks uncomfortable to me. However, G4 can wait - my first priority is the top and upper side as in my last analysis - something like this perhaps?

If I don't play 106, he captures in sente, and that's really very big - at least 10 points I think:

This seems to be better shape for me than what I had in my last variation. White has sente now, though. But I don't want to take sente and let white make a move like G4 or something like that, since to save my stones I'd end up hurting my corner.

On a grand strategy level, white's right side is almost connected to his left side, so my hope of attacking the white right group is more or less gone now. I can still aim at a separating move later, though, since I have some lightly placed black stones in the center. But I doubt I can threaten to kill the white group anymore.

So some ideas:

This is not great for black. White has good prospects at forming large center territory, and breaking up the top.

As per previous analysis...

Not one of the moves I was expecting, but still big for white.

Instead of responding locally (and making my black stones in the center heavy) I'll take another big move at the top.

But before I do that even, I'll make a forcing move (if white ignores):

The variations below are before I thought to make the forcing move. But they explain the reasoning behind the move after.

Not good for black:

I wonder why Black expects White to play at K17 after 11 (all variations pertaining to 11 in his Tactics section has it). You can find coins on the ground that are more valuable than those two Black stones; they serve no purpose and do nothing on the White group attached to it.

For Black to play 'a' and take the corner is better. 11 does not protect the corner and White could consider invading (e.g: at 'b') to take more territory away from Black.

Firstly, I think you should never show your tenuki in triggers in Malkovich games. It's not going to make a great deal of difference to me because my last move was preparing the top anyway, so it's not as if I hadn't noticed that's the biggest area on the board, but it does mean I could have for example played up there myself instead of responding locally if I so wished. Triggers are best left as the local moves!

So, I'm not too unhappy with this peep, but there's no way I'm going to block directly. The two stones he threatens to cut off aren't that big, and I'll gladly exchange them for swallowing up the middle in a big way. a > b below in my opinion:

The other advantage I have, is if he does play the cutting move, I'm going to jump to the top side and exchange for big gains in the middle area, he can't easily punish locally:

So much fun to have

I don't see any really great follow ups that preserve sente, so I'll leave it as a forcing move for now and go elsewhere.

This is great for black.

Protecting the cut in sente before returning to the top right. Now I can hane around the two and make things very unpleasant indeed for Black's entire corner, so I think this must be sente, and that cutting point is mostly fixed now

Other than the 3-4 exchange, I don't see a compelling white follow-up here after I defend. So maybe there was a weakness in white's position I didn't see originally and he's just moving to fix it in sente.

Once more into the breach, dear friends ... and this one is for the game hopefully. There are so many ways this can go complicated, and none of them look "bad" for White - it's time to break up his double extension, and to do it hard. So, why here? Because of my tactical analysis

These were the positions I'd considered:

Firstly, they're all on the left side of the corner because "x" marks his weak group. Either he's going to play to look after it and give me a fat corner, or he's going to run risks with it by trying to hold the corner. Either way, this is tricksy for him. So, "a":

I don't really like anything here for White. "a" is probably fine for Black, but he can simply play "b" and make a big corner and make me worried and running out with my stone. It just feels bad to be forced to do this when I'm supposed to be being all initiative-holding. "B":

Trying to take the top side in a big way. It's not too bad (better than the last line I think) but it's rather putting all my eggs in one basket and guaranteeing Black a good corner. "C":

This just feels too squished into the corner, and Black's outside position feels really nice. It's my first choice normally, but here I think Black has a really genuine weak group at the top edge. As such, I think the contact point at the original "D" (4 main options) is better. It's weaker, but at the same time more flexible, and I can benefit a lot more from sacrificing something in a fight if I can build an attack on that weak group.

Probe. Basically I need to decide what I want to give white and what I want to defend.

This way white can form a ko for life in the corner.

This way leads to complicated capture races in the corner. Not something I'd feel confident winning given the fight in the top left.

This is more passive. I build up solid corner + right side territory. But white starts to build up strength to attack the three stones at the top and is well into a solid moyo for center territory.

This way white steals much of the corner territory and top territory. But I have some thickness towards the center I can use to disrupt the white moyo that's forming.

Given all these possibilities, I like a hane on the inside better then a hane on the outside.

Prioritising the center and top side over the corner. I kinda hoped he'd go this way I think.

Seems good for black

Something like this is the only one that feels questionable. But I still think it's good for black. Though I can revert to the above line fairly easily if I do 3 at 4.
