According to the plan. I will secure the corner and threaten to expand it to the left. His weak group is better of, but perhaps not entirely safe yet.

This is a little heuristic: if you give an enemy group a ponnuki, it is basically alive. Exceptions may occur if the group is tightly enclosed.
In this case, the white group can now be regarded as completely alive and strong.

It's exciting that we're starting to get some comments, I can't wait to read them!
$$Wcm1 Prisoners: W=0, B=0

So which is better: extend?
$$Wcm1 Prisoners: W=0, B=0

$$Wcm1 Prisoners: W=0, B=0
Click Here To Show Diagram Code [go]$$Wcm1 Prisoners: W=0, B=0Extending makes a guaranteed eye, but also lets black secure the corner in sente. Capturing threatens means if black plays 2 above, I can tennuki, if I'm willing to accept less eyespace. The main thing is that I don't want black to be able to chase me around the board for more thickness, so I'm taking the eye. I'd rather be solid now so I can fight later.

I agree. I'm also very keen to read the comments afterwards.

I think it's about time to do something to the left side. I could approach his stone in the upper left, but I'm afraid he will pincer and I will end up with a weak group while he solidifies his lower left. Therefore I play in the middle, where I can extend to either upwards or downwards and have a secure base.

I must say that his invasion doesn't surprise me. I just had a hard time deciding which side to block, and I eventually decided this side is slightly better. I expect him to play the standard joseki. The only problem is that it will be gote for me. I could play the double hane variation (4 at 5), but there white can complicate things, so I think I will stick to the conventional one.

Ok, the moyo on the right is worth about 35 points of solid territory, which is a lot. But I'm not about to give up this game yet. I have some control of 3 of the corners, which is over 30 points if I can keep them. I still have to do something about the top and the left, but I think I can figure out something.
As for my last move, I think it's the biggest point, and black should have played there instead of the middle left. I can still make some good use out of the top stone I played before:
$$Bcm1 Prisoners: W=1, B=0
Click Here To Show Diagram Code [go]$$Bcm1 Prisoners: W=1, B=0I'm not saying this is the best way to play on top, I'll have to think about it some more, but there's potential. As for the lower left shimari, it has a lot less potential for growth, but I can ignore black 1 above and still fell like the group is solid. If he probes in side, I'll try to use the thickness I gain to attack his left group and reduce the right potential.

There are a couple of large points left in this opening. First I felt I must make my lone stone on the left more secure, otherwise he will play around C9 and I don't have enough room to make a decent base. I decided to play this first, since this looks so big to me and I think this is sente, so I get to play C8 later. If he doesn't respond to this, I will have a very powerful attack on his two weak stones at the top. Other big points are around G3, R12 and N17.

Ok, if he chooses to ignore my threat towards his weak stones, I will continue to attack. I intend to kill, and in the meantime I hope that my attacking will also indirectly help my own weak stone. I feel I'm ahead, but I'm afraid I have overlooked something. Time will tell.

I wont be able to spend much time on this during this weekend, so my next move will probably be on Monday. Sorry about that.

I still haven't had much time, but I will go with my instinct:
$$Wcm1 Prisoners: W=1, B=0
Click Here To Show Diagram Code [go]$$Wcm1 Prisoners: W=1, B=0Unhidden:
I know that Jowa says "don't run", but I think I have some chance of connecting to my stones in top-middle. I also thought of abandoning my lone invading stone altogether, and I still may, but I want to see how he answers. Not a good reason for a move, but as I said I haven't had much time to think about this, and I don't want to stall the game for any longer.
