Again, I don't expect to kill black, but I do hope I can gain profit by attacking. Running my cutting stones is important not because I expect black to die, but because after this fight is over a wall there will let me reduce the right.

After some more examination the key seems to avoid the atari at N14. The situation is quite complex but at least I seem to have some chances...

At first, I scoffed at this move by black. Yet it is one that I must respect. I don't think it was the best move possible, but it does prevent me from jumping and it does take away a possibly useful atari at N14.
So, since my opponent is solidly connecting, I must run solidly. This is the slowest possible running move, but I can see no other option. This variation does not appeal to me:

I believe my opponent's next move will be to hane around my stones. As a result, the fighting here will become vigorous and dangerous. I can see no sequence that guarantees my escape, but I did find an interesting option that would allow me to sacrifice these stones.

We'll see what my opponent does. There are many possible variations and so far I haven't predicted a single non-joseki sequence in this game.

Recently, I have been trying to go back to the fundamentals of go. Ladders, nets, cutting, connecting, liberties, life, death, etc. So, before I proceed in this fight, let's count all of the liberties on all of the groups involved:

Group 1 has 5 libeties Group 2 has 5 liberties Group 3 has 4 liberties Group 4 has 4 liberties Stones 5 each have 3 liberties Group 6 has effectively 10 liberties Stones 7 each have 4 liberties Stone 8 has 3 liberties Stone 9 has 2 liberties Group 10 has 5 liberites
I was once taught a general rule - in every fight, pay attention to the groups that have 4 or fewer liberties because: Groups with 1 liberty can be captured on the next move Groups with 2 liberties can be forced with atari on the next move Groups with 3 liberties can be pushed around on the next move Groups with 4 liberties can be brought down to 3 on the next move But groups with 5 or more liberties cannot be immediately threatened with capture - they may be dead, but they won't be captured
For example, if I play the cut at 'a', black will need to give the right-side stone more liberties, otherwise I can force it into my wall on the next move. The group may have 3 liberties, but me taking one away is sente.
Obviously Group 2 is the one most important to me, but it has 5 liberties. My opponent cannot immediately threaten to capture it. In the same way, I cannot immediately threaten to capture Group 1, so I don't yet have a way to force a response there. Group 6 is my wall, that is where I am running to because it is so strong; I have no worries with that group.
So, what about the other groups and stones involved?
Group 3 has poor shape. It is not directly connected to any group, so if I play a cut my opponent cannot directly connect his stones to the stone I cut off. A move against Group 3 brings it down to 3 liberties. The only viable moves are the cuts, because otherwise my opponent connects and gains many liberties. I am looking at possibly playing the cut at 'b'.
Group 4 is fairly safe. It is connected to stone 8 by a ladder and to the star point stone because of the shape formed with stone 8. Black cannot successfully attack Group 4, so I shouldn't worry too much about it.
Stones 5 - these are the stones I have my eyes on the most. Both with 3 liberties, so if I cut directly the next move will be atari. Unfortunately, I don't see how this will work if black connects solidly on the next move...
Two options for atari, neither works.

Or... wait! How many liberties does that black group above my two stones there have? I count only 4. And the one below has just 3!
Is this move to increase my own liberties really sente against both?

It is, but, sadly, a move at 'b' protects against both threats...
Then again... no. It couldn't be. Could the crude atari at 'c' really be the game winning move? Could keeping my group at 2 liberties actually be the answer to winning this game?

At 4 liberties to 3 liberties, I win the capturing race.
However, after all of that, then I need to be worried about my wall. Thankfully, the black group cutting it off is even weaker than my wall. And I have yet another wall to push that group into.
I think this is playable.
I think this is winning.

The connection at P11 may look more straight-forward. However P12 reduces one more liberty of the "inside group" (and also limits their "action radius") which seems relevant in some of the subsequent variations.

For observers:
My opponent again surprises me, but there is a reason I didn't show this variation: it doesn't work for black.
The reason is that I am the only one with ko threats. I have two local ones, and I don't see any move that white has on the entire board I would respond to. So I don't see how I lose.

This now became very easy. I will no longer have a weak white wall - I will just connect straight up. While he may be able to use his ko threat to live with the center group (and I'm not sure he can), after this I have no weaknesses and can focus on using the aji of the lower side group to either live or reduce black.

The funny thing is that I had planned (let's say: hoped for) exactly this sequence when playing . I still see no way to capture the M12 stones after , which would mean that the w "inside group" is captured. OC if I missed an essential trick and exactly M12 gets captured now, this would be quite funny...
My other concern was that w plays the wedge move L14 in between. This way, he can still sacrifice the inside group but cut off the "left side" (G14 stone) more easily.
There is still the possibility (among other interesting possibilities) that G14 gets cut off in the following. I would then have to try to reduce the white area from below as far as possible.

Yep, this ko was the hole in my sequence . I obviously have a weakness in considering kos and hopefully will find such things in future games. If I played P11 instead of P12 I think that in some variations I would lose by one liberty (will try to check that again later).
White has internal ko threats which can not be ignored, thus it will get tough. I will try to threaten to enter the top side and thereby staying connected and alive. But I will take more time and sleep over my first ko threat...
I accept your trigger. And I have another one for you.

I have decided that black has absolutely no ko threats I would respond to. For this reason, I play this ko threat, because I don't need 2 ko threats and this one puts black in worse local shape. The only threat I saw that was moderately viable was this peep:

L11 is my next move. No matter what move black plays, I will take his 3 stones.
