I'm not a very good counter in the middle game, but here I give myself 35, and Black 21 in the relatively settled areas of the board. Black has another 20 points of potential on the bottom (though I'm so unclear on how to handle the isolated black stone), but it all depends on how much reduction I get. Black also has better potential to grow via attacks, and has center potential in the bottom. I think Black is better, but it will all depend on how things play out.

It might be possible to attack the stone on the left, but I couldn't find anything interesting. So the choice is between playing on the top or playing to reduce on the bottom. There's a choice after I play on the bottom for him: does he take gote and reinforce, or play elsewhere?

If this through :w44:

, I can return to the top. I've executed a bit of reduction, he hasn't solidified his territory that much. Actually, there would be circumstances in which the cutting point matters. Perhaps I can make an attack on the left side stone? That might just be wishful thinking.

If he doesn't defend, then the reduction is huge. Moreover, I don't think there's a good way to strengthen his top group in sente, so I'm happy there.

I realize that I said earlier that Black might be better, and that might be inconsistent with playing a reducing move. But I still think it's the nicest move on the board.

P.S. See a in the original diagram? I'd really like it, and I don't know how that's going to play out.

And a trigger:

Sorry for the very slow response. Between work and a few other things, I'm still on the boards, but never for more than 5 minutes at a time.

I had convinced myself that I was going to ignore this hane and play on top. But after more reading, his shape seems rather resilient.

The ladder to the left is no good. Taking that sliver of territory on top is worth something. But is it worth ignoring this point and making Black thick near my weak group? I think not.

However, I think this move is big. If I'm not deluding myself, the hane at a is also sente. Seems like I should know that instead of having to read it, but reading is good practice.

I think I should try to exploit the weakness of the top right group immediately - responding to white's last move doesn't feel very urgent or big. I think if white had played as below first he could have fixed in sente:

I just don't get the feeling this is a hugely profitable ko for black... given the danger that c11 is in, it seems W has good threats. Thoughts?

I guess this is what he's aiming for.

A note on my thought processes: first I read up to white getting sealed in my head, and I had the hunch that white needed to protect after black protected on the outside. I laid the stones out on the board, and could see that the hunch was right. Next, I read what would happen if white played in the corner. Then, with the sealed variation open in my SGF editor, I saw what would happen if I leaned on

The SGF that I'm compiling is sometimes a "point and click" type thing when I get lazy, but primarily what it does is organize my thoughts and allow me to correct my original reading.

Because of my experience with playing correspondance games this way, I think daal's suggestion about the important of honing your visualization skill is really important. If I place ten stones on the board I can read so much more easily than if I try and imagine the continuation after playing ten stones in my head.

Edit:

Here I go thinking I was posting this very detailed analysis and I forgot the simplest move. When I looked at this before, I thought I had a really nice clean response to this, but I guess I didn't, or I can't remember it.
