@shaddy: After rethinking I agree with you about the third variation. But the first two are OK for White. In the first one White has sente, no weak group - even. In the second one Black has a potentially weak group on the right side he has to consider if he choses the empty corner, White is safe everywhere - even again. Do you agree?

1. variation:

I'm not sure if variation 1 is even, to me black is slack to answer at 3-3 and let white make a nice shape, but in exchange he got sente to get the last corner which is good. Net effect unsure. If white slides and I don't 3-3 I would probably play the one not two space pincer.

You did set 2 one point further, so in that case I'd play like this where a and b seem miai:

I don't think I can play like this with 2 one point to the left like in my original 2. variation.

Here is a game I lost. I have two questions:

1. Where was my first significant mistake early in the game (and what move should I have played instead)?
2. Looking before move 124...was the game still winnable for me?

1) r13 but personally I don't like r14 and would m3 particularly as d6 means you have the ladder.

Territorially, game seems somewhat balanced in terms of points to me. The problem is that white has potential on the top.

The biggest definite territory move seems to be here:

But can black afford for white to further develop the top? There's also the weakness at 'a' that black has.

I think the game is already good for white. The question is whether to try to do something about the top immediately to try to catch up, or to wait.

I don't know the answer to that.

My thinking went along these same lines, along with the question of whether black could play C9 to help remove the weakness in a more active manner.

:b1: is good, making territory while aiming to invade. But with :wc: in place, "a" is not great.

Although short, this extension is dynamic, threatening to invade the corner while shoring up Black's weakness. I prefer it to the previous diagram.

But the threat of White's expansion into the center makes me lean towards something like :b1: here.

Has the world gone mad? 3-3 in the bottom right is my move.

I can see Bill's argument of reducing the center, but I don't understand how the bottom right corner is bigger than the top right corner.

White's group becomes weak!

Can't really argue with that. Good point. I didn't consider this at all.

First I am surprised that White is seen better in the initial diagram. The problem with the lower 3-3 seems its slowiness. Yes, White's right group would become weak, but White has some influence towards the center and after 3-3 White has sente and could play another big move towards the center, effectively making its left group very stable plus increasing its top group potential.

I'd go with Bill's cap-like reducing move.

When looking at that board I can't help but want to use the sleeve tesuji to correct black's mistake here. (That would also make 3-3 better).

Q10 almost without thinking. Black needs a framework to match white's, and the right is larger than the bottom.

As for who is ahead... maybe white slightly, but not by much. Black's left seems a bit overconcentrated compared to white's corners, though these still have a bit of aji, and there's not that much development potential from black's left side.

o3. White is better due to black passively answering both of white's 2nd line descents on the left side which greatly reduced the 3-3 aji. (Though I imagine that shape may have occurred from white playing the footsweep). White's slide with big knight on the top is a little awkward but in no way make up for black's problem on the left.

I also feel white is better - maybe a 10 point lead? Black's position on the left is too over-concentrated.

Compare to this "even" position:

Instead of the third line territory that white gets above, your variation gives white a position on the 4th line.

Anyway, I'm a little impatient, so I wouldn't feel good about playing calmly. I'd want to break up the top to restore the balance of territory. Even if black plays another move around 'a' or 'b' below, I don't think it's enough to offset white's lead.

But it's hard to make an even game from a losing position, so it's hard to say that invading the top is a good strategy, too. If I had more patience, I guess I'd go with 'a', above. But it doesn't look like a winning game.

At this point, I'd be biting at the scab on my thumb - it's the habit I have when I'm in a tough situation. The skin on my thumbs is really wearing down these days...
