Good, my opponent was worried enough about my F3 stone to spend another move there. I considered capping at O6, as suggested in passing by Chew, but we seem to be playing the cash in and fight game now.

encloses my corner and peeks under the skirt of White's budding moyo on the bottom.

At this point, it's almost mandatory for my opponent to jump into the right side in the next few moves. From there, the fight for the center begins.

Here's a possible continuation, though it's far from well thought out ... just some points that I think might be important.

You called it. As MHO said, now is the urgent time to handle the right side. 4 is a pretty flexible way to do it, aiming at weaknesses in the corner as well as stability on the side. I am content to have the bottom made into dame if need be, so long as I can similarly negate the right, more or less. I considered trying to do make a larger moyo on bottom, but my opponent is better set up on the right than I am on the bottom, so I would have no assurance of making a comparable amount from my efforts. Instead, this double approach gives me options on the right side and the corner, which are both much more appealing than the bottom.

If the game plays forward as suggested by my opponent, my right side group is stable, because the 'a' options are miai to expand my base. As a result, I could safely take sente to select from the 'b' options.

Alternatively, if my opponent prioritizes the right side by pincering, I can either escape or attack the corner fairly successfully.

This is just a quick at-a-glance followup possibility, but it demonstrates that I can more or less settle easily on the side. 'a' is another option for 2, but it seems too passive at the moment. This does leave lots of interesting options for later, like capping 1, eventually invading the higher right side, and extending on the bottom.

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.

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:

Stuff at the bottom that could get "interesting"

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!

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.

Here's the sequence to be afraid of:

Black chews on White's two stones ... might not be ideal for Black, though. More reading is required.

The next thing to look at is after blocking, can White get away with a tenuki?

White has to be aware of both points a and b.

Anyways, maybe Chew will find a better line for

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.
