I had thought I could ignore this, but on further reading, I need to defend. Sadly, I'm not sure whether it's a good idea for me to continue this fight, but I'm going to. The outcome is far from clear to me yet.

Hmm, empty triangle. Important to reduce that W lib ?
How about :b1: instead ?

Did you think about any other ways to defend?

Now he could cut me at F6, so I reinforce the connection somewhere

I apologize for the delay. It's been a busy week at work, and I haven't yet had time to properly assess the board.

@Uberdude:
I also considered O4 to defend, but I'm convinced there will be a ko fight somewhere in the near future (there almost always is in my games lately) and did not want to give any extra ko threats. Maybe that's silly, I don't know. I dislike the empty triangle I made, but the solid connection provides fewer threats for my opponent later. Ugly, I know ... :blackeye:

Well, the empty triangle is an oft-maligned shape that needs some love ;-) But there was another other way to defend that achieved something else useful too (but did give more ko threats than yours).

My thoughts concerning this move:

1. Keep his groups separated.
2. Enclose lower white group (or try to, anyways).
3. Leave my two stones in the middle of the group with some aji.

These are all vague ideas, and I'm not even sure I'm performing them in a good way, but this feels like the right place to play at the moment, at least to me.

My group in the middle is not alive yet. I'm strengthening it into a direction where I might get the chance to connect to the upper group or making black prevent that connection and thus gaining another move for making life.

Hmmm ... I think this a dame point ... but I want to be able to get back to my attack soon. Need to be patient.

I can't find a better move right now. I hope I can do something that feels useful soon. :P

I know this is a very slow move. I think that my group is not yet alive. I considered jumping to P12, but it doesn't seem to create eyespace. Another one I considered is G11, it also doesn't seem to create eyespace and I dont want to strengthen black there. I didn't find any move 'outside' my group which would create eyespace well, so I chose this slow move which gives me 2 eyes.

Time for some reduction here. White is looking solid elsewhere, so time to reduce and look for other opportunities.

I feel like Marcus' last move should be a mistake, though that seems to be a little hard to establish. Maybe I don't like that it's on the second line. I was looking around here:

The move on the left doesn't seem to be sente (because of eg. 3, 4).

As white I would still like to dream of a sneak attack around 'a', but it seems unlikely.

Bottom right I might have liked '1' as a starting place.

Top seems like it should be unconscionably large. Imagine white 'b' instead.

I think it's too big for black to cut this stone off the corner group.
This variation is not good:

More reduction. W has to be careful about where to block. I should be able to get fairly deep into the corner.

As said in the previous post of mine it's no good to block at S5. So I connect my stones.

Still in good shape here ... I also think White owes a move. I'm pretty sure I can clamp if he doesn't, and he can't stop me:

Those 4 stones basically become mine. I think that's rather painful for White. I suppose he can resist this way:

Still ok, I think ... White still owes a move in this last diagram, too. Very nice reduction if he doesn't block.
