Joaz, a large part of the discussion is about whether it is better for white to play at or a. The answer is not obvious, and there are dissenting opinions. However, there aren't really in-depth discussions, as most of the posts are one-liners.
If I were to take tenuki from here, Black would end up with a piece of the pie that's just a bit too big for my taste. It's also not a trivial matter of whether I lose one or two stones; for instance it also plays a part in the effectiveness of Black getting to play K17.
One may wonder if W playing N16 is feasible instead of my last move. I think if I were behind this game, it might be something I'd consider but it's a very reckless move. Actually Black needs only to pierce once at M15 to give me two cutting points, then retreat by connecting from underneath (not with N18, but with a monkey jump on the first line)...the sequence is very cobra-like.

is a ladder breaker for the cut at 'a', sets up a geta. The white aji is tricky, though, especially if black plays 'b' sometime. Then both cuts have to be defended.
I think this is the optimal way to use the thickness I got from the top exchange. Protecting the corner with C15 is slack and doesn't take into account the global situation as my focus is gaining control of the center. If this is accomplished, aside from the point benefits it also reduces the value of not just his 5-4, but his entire bottom formation as well - it's not a territorial formation but an influential one, but if the opponent controls the center then it clearly becomes difficult to utilize it efficiently and he will be forced to change his plans accordingly.
I wonder how he will handle his D13 stone, it's unreasonable to sack it because it's in such an important area of the board as the left-center area will become too big. If he dives into the 3-3, because I am strong in this area and D13 itself is far away, I will probably go for the kill. At the very least I can seal it in properly (the presence of the H18 group makes all the difference in the world), which will only guarantee D13's death and give me large territory on the left. Perhaps he will show some sabaki techniques here with his stone.
I understand why you chose this area of the board. May I ask why you chose that specific location, instead of high, or wider, or anything else in the local area?

Could you show a few moves showing how you might go for the kill if Joaz goes to the 3-3 point?

I'm going to treat D13 lightly for right now. If he wants it, he can have it, and I'll go for the corner. I think that he will find it to be like eating celery: the effort expended is not worth the calories gained.

...whereupon once he commits to letting me have the beginnings of eye space I can risk committing myself to a fixed group with and then neutralize much of his influence with . My gut feel is that my group can survive the most vigorous attack. He will get a modest extension along the lower left side and I can bring my hoshi stone into the game by poking it with C6 or D6.
Hey everyone, back from the dead. For those who haven't looked in the SC2 thread where I usually posted throughout the summer, I got into a tablesaw accident a few days ago that lacerated my left index finger. Now before this incident I was busy with school and SC2. School's fine as I write with my right hand, but now I find myself unable to play SC2 seriously so lately I've been kind of getting back into Go. I never really did abandon the game though, as I'm still in the L19 tournament and even played a few casual games here and there. But since the incident I've been playing more (under an anon account) and taking the game more seriously for the time being. Anyways, I was reminded of the Malkovich games that I postponed and figured now would be a great time to resume (and finish, even after my hand is healed and I go back to the world of Aiur). Since I made my last move in my other Malkovich game with Tabemasu and he doesn't come on as much here, I'll talk with him to let him know I'll be active again in the thread so he can play his next move.
I suppose the biggest debate one has to come across here is whether W should curl on top of or beneath C16. I feel curling on top of the stone is better because it gives me better control (+ territory) to the corner and D11 keeps his group in check. Furthermore, it makes D13 less effective as I don't have to worry about the crosscut at D15 that I'd have to be concerned with from curling beneath C16.
Regardless of B's followup, the general idea that I need to follow is to keep the group on the left under as much pressure as possible by utilizing my thickness at the center and making maximum profit. And for those wondering why I didn't use the term "hane", it's because I didn't want to use "haneing" (good God) or adjust my sentence structure to force myself to use "hane" instead.
I should throw out there that my WPM decreased dramatically since my accident, so expect brief messages until after my hand heals (shouldn't be too long; <1 month)...you have no idea how long it took me to type this much .

It's hibernating. After the routine 6-month extension from the IRS, Oct 15th is now the defacto tax due date for a lot of us. I'm probably playing too much already with the prokovich and big brother malkovich. This will have to wait until after the 15th. Then one of my employees goes on vacation, so maybe after the 20th...

In the photo, those look like... gloves? You were using gloves with a tables saw???
Yes. I wore them because my hands were cold, they prevented splinters, and also helped with grip. Those are enough benefits for me to wear them despite the risks.

Araban, with the state of your typing hand, would you be better off doing video commentary again?
I might consider that. Though I seem to be improving quite rapidly with 8-finger typing (I just tested myself on typingtest.com and got 80 wpm ). I even played a few team games of SC2 and did okay.
The taxes are done, the employee is back, so I'm back to something resembling a normal life.
With the previous move I offered to trade him the D13 stone for the corner, if he wanted to play at 'a'. He didn't go for it, preferring the safer line of retreating into the corner. So I have the possibilities of connecting at 'a' myself ( which earlier I favored but now looks too heavy ) or the crosscut. I'll probably only play 'a' myself if it looks like the only way to make life there.

A little digression for future referrence: if I do crosscut, the only reasonable play by white is to extend westward. There are lots of ways that things can go wrong if I am allowed to chase his star point stone southward. Below is just a sample variation illustrating the bad aji.

...where 'a' and 'b' are miai, I'm locked in the corner, and he has more than enough compensation in the center.
What I would like is a way to play B17 such that it does not get locked in. All that this requires is another stone nearby, like the marked stone below:

So, if I can get in one move like B13, I have good prospects in the upper left, and much of his central/left strength gets nullified when I have a living group there that is not locked in. Thus I am going to leave the corner aji alone for now, and see what happens on the left side. (End of digression.)
I'm going to play the natural leaning move, pushing the play away from his strength up top and toward my hoshi stone in the lower left.
Well one thing that's obvious that I'd like to get out of the way is that playing elsewhere is not feasible. Doing so would allow B to press my stone down with 'a' and gain thickness that nullifies by thickness near the top.
So how to support my C11 stone while trying to utilize my K15 thickness was the big question really. I think trying to support the stone by extending along the side with a move around 'b' is too timid and still allows Black to play D10 regardless.
By playing my move, I am trying to drive him up the wall while at the same time providing support for C11. I don't need to kill, just gain enough profit on the side (and sente would be nice).
This is really a no-brainer. I cannot let him have F11 or F12. Even without considering his strength up top, letting him get ahead in a pushing fight is bad for me. And when his strength up top is taken into account, letting him push me toward that strength is is absolutely out of the question. I, of course, want to push him toward my star point stone.
He can't get F11 because I just played there. Because of my threat of D11, I'm 99% certain that he will play E10. My next move will have to ensure that he does not get F12. I'll probably play as shown below because at first glance it is the prettiest shape, although 'a' and 'b' are possibilities.
Overall, I have reservations about the the wisdom of white's latest move. As a theoretical issue, it does not seem ideal to force me to strengthen my group in the face of his northern wall. Indeed, as a practical issue, if I become too strong, I can start attacking it. The diagram below shows what can happen after some hypothetical exchange of stones in the mid-left.

Trigger for Araban:
If white 36 E10, then black 37 F14
For everybody but Araban:
The goal here is to cover my weak spot at E12 and simultneously try to steal sente by threatening to invade around E16 or F16 or G16 or even F17, maybe in conjunction with a crosscut and/or K17. Sente is very important now, for the first person to get a move around B6/B7 is doing very well on that side.
