seems to be a busy week, and a slight flu doesn't help - moves may stay more infrequent for a while :(

Oh, this is interesting. White's trying to build momentum by threatening black's upper group. I'm considering capping the running group with a two space jump, or possibly just haneing with the invasion stones, since my opponent didn't respond to the attachment. I will need to consider it for a bit, though.

I considered the cap at A, as I mentioned, but didn't like black's prospects after white stands up at C. I also considered peeping at B to strengthen the invading group. I ended up deciding on C as it's a big move and possibly the vital point. In addition, I'm pretty certain I can eke out life with the upper group if I tenuki it, starting with peeping from the other side at D to make an eye locally or cut white. I'm not promising that things won't get messy, however.

So, there's ko aji here, if that's how white wants to play, but I think I'm in a decent position for ko since it seems heavier for white. Alternatively, we could both just connect and then we have a running fight on our hands. I'm okay with this too, since I could use it to cut off the right side better. In either case, though, I feel like I'm a bit behind due to the top side, so I'm happy for something complicated to happen.

If I could just be sure of sacrificing the five stones on right, I could consider fighting the ko, but I'm afraid black would go after my bottom right corner, which I can't let go. And I see at least three threats against bottom right, which is too many (starting with A below).

I expect white will run out the top group with A rather than cut at B since A is so devastating if black plays there. I strongly considered playing B myself, but if white cuts, I can push out and have a ko with a local threat or two to win it along with damaging white's running group in the process. I'd love to be able to play A myself now, but I think that the cuts are too painful without any reinforcement. I briefly considered trading to attack the right side group, but I'm not sure that I would be strong enough to guarantee a kill, and if I don't kill, it's not enough since I would have given away a lot on the left. In any case, I could always consider capping after white plays A. In that case, though, perhaps I should make the sente eye first to reduce pressure on the upper left black group (black c -> white d, black e -> white f, then black g -> white h to prevent white's peep).

In any case, if I can get white's group running and heavy, and then play a central splitting move, I think white will be in trouble, as I still have the cut at Z to split white further.


@observers
I would specifically request comments on this situation starting with the invasion on the left and whether this plan is a good one or if black should be looking at something else, if you'd be so kind.

I don't like leaving that cut. Even ko cut makes white have a lot more flexibility. How about hanging connection? That also fixes e4 cut (But yes isn't as solid as game connect so white has some peeps or maybe some tesuji at e4 but the cut above is more important IMO). Note that d8 peep is not so effective here (even with d5 push first) as black can resist at d9 due to white's weakness above.

Next e.g. following seems to go towards making the cut at :w75: interesting? And if black misplay, I could get an attack on top group instead?

Hmm... That's a good move, and one I'm wondering how I didn't anticipate. I think I am going to push and cut instead of responding by connecting, because it makes my previously sente eye gote in any case, and if I live passively, my attack comes to nothing. There's enough weaknesses all around that it looks like a decent fight, at least. I like attaching below :w69: because I have the ladder that runs into M5. I've also considered the other cut at F11. The other attachments to :w63: allow white to stay connected.

None of these seem ideal, though, and that last one looks like a crazy multi-step ko for black, so I'm not thrilled.

These last two look okay, as I don't think white can resist the peep without getting everything cut off or losing a lot of aji. I don't know that this is how things will actually go, but it seems reasonable to me, and getting the shape point with the third move seems ideal. In the last diagram, I count black ahead by at least the center capture, but it still has some aji and white has sente. If white trades cuts, I think the game is still fairly even, as well, despite white's new center potential.

As a result, I'll play this way and see what happens.

I have a go tournament this weekend, but I'll try to make the next move here too.

Whoa! I admire the fighting spirit, not connecting, but I did not even consider varying here possible - wont I get too much if I just play like below ( this is my first intuitive idea here)? But let's see if I can find something even better...

Back from the tournament. Won the all the games I could&should, lost only those which seemed hopeless already on the pairing list...

I simply can't stop myself from cutting here, perhaps there is something smarter, but this feels too good. :)

Another fun possibility for later: after the sequence up to white C below, it seems to me I can either capture some b stones or connect white C to top. So black side is not as sturdy as it seems.

Some strange reading from both players but particularly skydyr: a lot of depth but not enough breadth.

This is a massively long sequence but so many early moves are close to nonsense. White peeped: black didn't connect. So white cuts. Did he not consider this? And what are 3/4/5/6 in that first diagram? Now white's centre becomes thick and that potentially weak group on the right becomes a wall of a large centre almost-territory. Losing h13 is so big. Yeah black territory on the left is nice too with e10 push and cut (to the left of course, Tim's most recent diagram with cut on right just makes black run out of liberties and die) but white's group there was a heavy group he can happily sacrifice for the centre power.

I'm caught up with stuff I had to put off, and should be ready to go.

This feels forced.

I want to take A below, but I managed to convince myself that I want to first see how black responds to this - if he connects at B, A is more sente than it would otherwise be?

A aims to a) build center b) lessen the threat of a black cut at C.

After :w79: the question is how to further build the center while at same time reducing black bottom. I'm not sure at all the plan here is best, would like to read other's opinions on what to do at this point after the game...

I'm a bit baffled by this move. On the one hand, it looks like it increases the aji if black responds passively, but on the other hand, I'm not sure that it's really sente if I can give up the one stone. I'd rather play one point below :w77: or ignore it completely and go for the outside in some manner. N8 looks like a good candidate to increase aji, or maybe an easy reducing move around H10, or a surrounding move like L6 or something. I think I like the reduction best, as it seems the most active.
