I'm going to try to stabilize quickly this group and then invade the upper left corner.
If I don't come up with something quite acceptable I will resign

Interesting, apparently black didn't approve of my plan so this counter came up. However, I'll just make the ironpillar here since my plan is to build more influence here anyway.

If black lives now:

Not sure. (1) is not certain, but it shouldn't be that much different in principle even if he defends with some other move.

Now I got a secure base. Here is my plan. If white doesn't play 3, I will play somewhere else, as I will be able to reduce the upper territory later (because of the open skirt).
The sacrifice of the black's group down there cost me around 20-25 points, so the reverse komi as been greatly reduced...

Black forcing me to kill his group. It's hard to complain. I assume black will tenuki now, so I will have a target here for attack later.

I'm not sure that I'm alive if white play x, so I want to play the double sente move a before, even if I'm not sure white will answer it. And I'm keeping the dead black group has potential ko threat for later.

I think this is a bit painful for black, I'll just continue to develop my influence. Black doesn't seem 100% alive yet either. Will he take sente and invade top or add one more move to protect?

following my plan. If white answer and after the sequence I will play a, b or c... I haven't make up my mind yet.

I think White will play 3 because this shape influences the upper side even more! Do hane on the first line at this point of the game is unbearable for black, I think this may cost him the game. But what should black do instead? The general mistake was already the attachment here:

Black needs to keep his stones light and get out fast!

I would abondon the stone for this moment because getting out looks not good, if Black really wants to get a light move like 1 looks best I think.

But what to do now instead of the hane?
Well black is already in big trouble, I believe 'a' or 'b' are now the only moves, but white will gain alot.

Black played a big endgame move, but now it is uncertain that (a) works for black later.

White (b) will help black make life, so There is no real need to play there now because black will not push at (b) now anyway since it would just make matters worse, so white can probably get the endgame move later anyway. Now black still has to worry about life.

No comment, I just feel it good...

It's important to move first here, but black is starting to look busy on the board. I will just keep up the aggression for now and grab some cash while black is trying to stay alive.

Sry for not giving good explanation. I'm making a contact move to stabilize quickly my G17 stone

Gonna go for the corner, not sure how I would handle a crosscut if I hane so this will have to do.

I don't know what to do with myself... I don't know what to do...

I'll just grab the cash with a shape that has minimum aji, with bottom dead group, white is starting to catch up to black in terms of territory, and black still has two weak groups, so this is starting to look quite good.

If black goes for greed, I will harass his shape at (a), I guess black will (a) directly or try something like (b) or (c). I'll just push and make more thickness if black (b), (c) seems like overplay so then I will fight hard.

I guess I can look at his left group while waiting:

In terms of pure eyespace, black doesn't seem to have enough locally, so whatever chance black has will relate to the aji in the center.

Blocking the center doesn't seem to work since (a) gives life now. However, getting the outside thickness is worth a lot in itself so this isn't too bad for white.

White can let bottom live:

White should gain like this because it also removes the endgame move at (a). Adding the centerinfluens, this would be a happy deal for white.

Since all these variations are painful for black, I would assume that breaking out is what black should try:

(a) or (b) probably, but when we run along in the center, the top group is getting pressured, white should thus still have the initiative and be able to attack that group and later switch to (c) or (d).
