Okay, feeling fairly good about the opening. The thing worth noting is, my opponent has gotten more central thickness than I have. I need to make sure that it does not turn into too many points. There are several points that I can claim that would help me to reduce this potential, and I would love to keep sente to get them. For the moment, I expect something like this:
This last play seems very hard for black to kill. That said, I feel like white is comfortable on the board, so this looks fine for me. I've been trying to play with a more territorial focus lately, so this all seems to go along with that. For example, for 44, I could simply cap 45, but this takes points, stabilizes me utterly, and is fairly sente. In exchange, black gets some points too, but at least I'm not forcing black to take 44, points and all. Regarding my opponent's last move, I think perhaps he should attacked first, before stopping to defend. If I get 42 here, it buys me a lot of points and saves O4. MHO can do some of the attach-and-crosscut kind of stuff around 42, but most of it should turn out fine for me. If B does not take 43, I will, as it is MASSIVE. It singlehandedly neutralizes much of the middle, as well as destabilizing the stones below in a big way. I may actually chose to play it before/instead of 42, as it's so big and is relatively sente. I might be able to suffer black getting 42, if I get a real attack on the left side.
Marcus, thanks again for the game. This is forcing me to do a lot of the sort of thinking that is good for my game.
I want to make my groups as solid as I can. I'll lose more points if White gets to attack multiple groups. Chew is right: F12 is pretty big. I will likely need to take that soon.

Ok, it's an open game, so I'll throw some fun out there. It's semi-spoilerish, so don't look if you don't want to, but it's been playing on my mind:
where exactly is that good point down there for White to defend? I'm clueless at this point, but leaving it doesn't seem clever either. Well, good luck both of you
This may be a little greedy of me, but I feel like I can cover most of my weaknesses on bottom while provisionally saving the stone to the right, also. If I hold onto this, the game is okay for me. However, I am willing to lose half of the bottom in order to get F12 in to attack the left group. I tried to take a look at the aji on bottom, but I think I can weather the storm...
'a' points are miai. While I am sure black can probably get more than this, I feel like I won't die outright, so it's good enough.
I really wanted to play on the left side, but this just seems way too big. If I really needed to start a fight, I would attack the left, but it's not worth the risk right now. Keep reminding myself, taking territory is good. Taking it solidly is better, but even looser frameworks tend to compensate when invaded.
Oh hey, Topazg posted possibilities down here. I kind of like his last option, but I still prefer mine. Here goes!
Let's see what Chew does here. Topazg has outlined the weaknesses at the bottom. There are also ways I can attack the base of the right side group, if I find it necessary later. Let's see how this plays out ...
I thought about building below with L5. However, if black peeps at N15 then takes something around M17, it begins to build biggish points in the center while harming my group in the top right. This route, I take simple points and threaten to do something up top. A simple cap after this would negate the middle almost entirely, or I could consider assorted invasion points that may be interesting. I haven't yet found an invasion variation that works for sure, but this move starts to make crazy invasions and attachments safe enough to consider. I can play defensively with my group on the right side, as I'm happy with two points there. I THINK I will be able to be okay there, since I'm not going to be greedy. As far as the bottom, I don't feel like I need all of it. As long as not TOO much of my stuff there dies, I think I can allow small life for black, or decent thickness, or whatever. I just need to make sure I don't get cut in half and murdered. If need be, I can sacrifice both of the rightmost two bottom stones, but I'd like to at least get something for it if I do. The rightmost stone itself is easy to sacrifice. If I lost it, but solidified the rest, that would be fine.
Really, it depends on my opponent now. Where looks good to you?

I need to build up some more strength for the coming battle. I should be able to seal White in here. The question becomes ... can I do it in sente? The first few moves seem forced:

This builds a nice wall. Of course, there are a number of ways for White to play this out differently. From my own reading, I think I can handle anything White tries and gain something out of it. However, I'll let MHO do some reading and see if he finds a better line than this.

Ah, expected you'd do some kind of attachment inside, or something. Like you said, this first move is fairly sente and forcing. One thing that I need to be careful with is this:

This is the scary move, from my perspective. I am going to have to look into this, and a few others. However, this is only an option if I tenuki, so at least I have a chance to prevent it. If I take 'a' before black can get the marked stone, for example, it prevents it from working in semi-sente. I'll have to look deeper, but for now I'm fairly well forced. I don't like the idea of trying to run out. I would be perfectly with getting shut in here, as long as my opponent has to block me in in gote. If I get sente to cap the top, for example, the middle will turn into small potatoes. I'm going to have to be careful in this fight, though, lest I get locked in in gote, or just die. I had underestimated how scary this attack could become, though I still THINK I may be fine.

This move might need some more reading for White. The simplest play is to block as normal. Otherwise, I'm going to push and cut. You know I will, eventually.

Marcus, no reason posted for #43? It seems you are far far too interested in the center. #21 was very bad also, locally it should be a simple extension on the 3rd line. The reason you gave for #21 was *if* white doesn't answer you reduce the left. But after securing the group on top, again if white doesn't defend left you can simply split it.

For what it's worth, I think this is better than pushing and cutting, if I were to tenuki. However, in light of this... yeah, I can't. That said, this whole fight is much scarier than I thought. Now, I just want to live.

The reason you gave for #21 was *if* white doesn't answer you reduce the left. But after securing the group on top, again if white doesn't defend left you can simply split it.
In response to this comment ... yes, was a terrible move. I noted that later on in the game. I tried to be overly clever, and proved just how bad the move was later.
As for ... I'm not sure how bad it is, or if it's a reasonable move. My thoughts concerning the move were similar to Chew's ... my left side group isn't in bad shape, but it's not all that strong, either. F12 seemed like a good way to make an attack on that group harder.
It's true that, in this game, I have been very concerned over the center, perhaps overly so. I have a tendency, in my real-time games, to neglect the center until it's too late to stop my opponent from gaining a huge advantage there. I'm currently trying to find a happy middle ground ... not there yet.
Thanks for the comments and questions. I encourage anyone else with questions or comments to please post.

After looking at my options for a while, I decided to keep this. Either it gets me out into the center (as I showed in my last post) or my opponent ataris me and gets cutting points. Either way, it stops the threat of S6, the best move my opponent has to kill me.

I don't see any reason to not take this cut. If this is aji-keshi or a wasted ko threat, I'd love to hear it. It just seems to me that any ability to pressure it buys me, however slight, is worth the loss of ko threat.
Marcus: Fear not, I was busy with a week off work and friend in town. I hope you feel better! You can treat 'a' and 'b' as a trigger, if you would like. If you take 'a', I will be taking 'b'.
was a terrible move. I noted that later on in the game. I tried to be overly clever, and proved just how bad the move was later.
... I'm not sure how bad it is, or if it's a reasonable move. My thoughts concerning the move were similar to Chew's ... my left side group isn't in bad shape, but it's not all that strong, either. F12 seemed like a good way to make an attack on that group harder.
