Folksy wisdom tells me adding an atari is bad.

Yeah, doesn't seem great to me. Pushes black further into the centre (he should either extend or capture solidly). So, I don't think it's worth whatever aji it may leave.

Now, just the details of what approaches to play and when...

The position before this move is exactly the one I predicted at move 10. At the time, I viewed my next move as an option between something around a or b. I felt that I could handle a cut at z, so I should consider one of these two moves. Now though, it seems to me that whatever I would play, w would cut first at z and see how it goes before responding to my move. White would be happy creating complications and wouldn't mind having a group floating in the center if black had one floating there too. Makes me think I should play z myself. Z looks very thick, giving me a solid position facing the center. It looks like the right thing to do. I expect that he will play at a or b himself. I will try to respond calmly and without jealousy. White has some definite points, but has not weakened any of my handicap stones. Black has nothing to complain about.

This isn't a comment about anything that is still to come, so everyone can read it, I won't hide it.

Going back a few moves.. 1 seemed like a mistake for white here.

Eventhough white's corner is big, the marked black stone is in a good position and black has sente. If the marked white stone was at a, I think it would be better. Anyway, black's responses were really bad. He pushed white so that white has good shape and a lot of territory, while black still has a lot of aji left and didn't gain much. The intuition was also wrong, forcing white to connect is never good.

I would particularly appreciate any reader's thoughts regarding the board position before this last move of mine - but please hide them! (@Pancake - your previous comment is the sort of observation I'm very interested in hearing, but I'd prefer to read that type of thing after the game. Thanks!)

I must say, I feel totally clueless. Below, you can see my first thoughts, in the order that they occurred to me (after that came some thoughts in the Bermuda triangle of a-b-g):

Here are some factors that enter into my deliberations:

1. The jealousy factor. My first impulse (a) is jealous. If I'm not going to be jealous, I need to be getting something large myself. Problem is, his position on the bottom is already secure, whereas my compensation will most probably not be secure yet.

2. The aji of c6 is reminiscent of a large hemorrhoid. (I probably wouldn't be thinking about that yet, without having seen Pancake's preferable sequence two posts ago).

I'm going to dismiss a and d for now. They are too close to thickness, and they seem not only jealous but also have the tendency to lead to two weak groups.

As to the rest, I wish I knew how to evaluate them. Kirby might say: read! I tried, but there are way many possible continuations. Most of my "results" seem utterly unlikely to actually occur.

b seems like the obvious move, and I guess that I need a really good reason to play elsewhere. Were I to play c, f or g, I would not be pressuring white, so he would be free to play a double approach at r6. Would my advantage compensate? I'm going to guess "no."

The only remaining move to consider is e. What is the difference between b and e? If this is a matter of reading continuations, I'm out of my league. To me, b feels as if it might give me more leverage to reduce his bottom, whereas e might lead to me "sharing" a bit more of the corner.

I'm going with b, because it seems less wimp-like.

Is there any reason you didn't consider "z"?

Twenty-two seems fine. I would also have considered the attach on top, as I think I mentioned before.

(Albeit I only half remember this joseki, I'm not sure if :b26:

is the best option. Or :b24:

really.

Edit: It might continue with a-b-c or something, I'm not sure.

I feel this can reasonably be expected, after which I'm thinking about an invasion on one of the circled points (I have some reading to do).

I am changing direction to top and left, because I feel the area I could stake out across bottom by taking gote is not big enough.

I'm finding this decision even harder than the last one. Basically, nothing looks particularly good. Again, the lettered moves are the ones that occurred to me listed in the order that I thought of them.

My first impulses are to respond somewhere on the top left, and that seems natural, as my hoshi stone has come under pressure. There are two reasons however that I hesitate to do so. One, is that I would be following my opponent around the board, letting him get the better big points, and two, I have a 2-1 stone advantage on the bottom right, and if I don't get sente on the top left, (and I don't see a way to do so) that advantage will be gone.

How to evaluate? Let's say, I play at f. A white response at e looks to me quite hard to deal with. I suppose I can manage, but how much of a benefit is the move at f? Again, white's secure position on the bottom left could mean trouble, i.e., while chasing o3, my corner could easily become thin.

I think I'm going to have to bite the bullet and play on the top left. a looks better than d, just because I have all high stones on the left, and he has gotten strong on the top. b looks like the wrong way to use the hoshi stone. What about c? It seems more consistent with my attempt to make thickness in the center, so that's what I'm going with. I'm imagining the following continuation:

I have some thoughts to think here, but all of them involve playing :w25:

I think after this invading the left should not be hard. However, if an invasion still seems possible afterwards, should 27 be at 28? Invade the 3-3 and settle top from top right? What if Daal plays 26 at 27? F18 after F15?

After this, I think the marked white stone is not in a good place. Invading 3-3 seemed redundant if I was invading the moyo anyway.
