Still haven't shaved. I guess I'll do that next.
Why, what's the hurry ? :)

Well, two things accomplished.
1. I shaved.
2. I played a game, finally, this week.

It was against KGS 1k. He had some colorful language near the end.

Here is the game, with a review from black's perspective.


Notably, he should have killed me on the top left. It's kind of amusing that I tenuki to let it die, he didn't kill it, had another chance, and still didn't kill it.

So that group should have died. Nonetheless, it was still an interesting game.

The marked move was somewhat aji-keshi, I suppose. My intention was to develop potential in the center, but black fixes his weird connection pretty well. I wonder if I need to do this right now.

In fact, splitting the stones doesn't seem that bad, if I can get a good attack on his stones. For example:

Maybe black won't play that way, but splitting seems viable if not now, in the future. And after this move, I erased that possibility.

Not sure if the atari was ideal. It's not 100% clear to me that this is the direction I want to go. For example, later, maybe I want to pressure his other stones:

Not sure if it will work, though. I guess I can see why I played this way.

Maybe instead of doing either atari, I should simply deal with the stone first:

$$ ---------------------------------------[/go]
Then later, I can decide on 'a' or 'b'. I think I like this path best - don't decide atari, even if he captures my marked white stones.

These are the main points of "aji-keshi" I'd like to point out. I will get to the game review from my own side later tonight.

Already, I should note that:
1. I shouldn't have given him the chance to let me die in the top left.
2. I shouldn't have allowed such risk in the opening when he could have cut me in the bottom left.

I think this is too loose. I should have played tighter earlier, and it could have made the K4 stone weird.

Things were getting slightly risky after black's move here, and I had a pretty good game before it I thought.

So maybe earlier, I should make things simpler:

I think the atari is a weak move, and I don't know if I want to do that. I think I should move with the other stone first to see how black responds:

I can aim in the 'a' and 'b' area next as miai.

These are the main points I think I should focus on.

So some highlights:
1. Think more carefully about the technical details (type of connection to use to push down, etc.).
2. When game is good for me, avoid getting into a crisis situation where black has a big moyo. I could have just reduced this and the game would be simpler. When I'm ahead, try to wrap up the game in a simple way.
3. Play the big area (e.g. I like the tengen in Position 5).

I think this is too loose. I should have played tighter earlier, and it could have made the K4 stone weird.

If black responds to the joseki, K4 looks weird:

I don't think there's anything wrong with this position as yet. White can come out easily enough and black's original keima looks overconcentrated. Black's choice of direction after the 3-3 seemed kind of odd, to be honest. When black ends in gote, overconcentrated, and low on the left, it seems good for white.

Maybe that's bigger than what I played.
I'm not so sure. A black play in that area could reduce quite a bit, and also expands black's moyo on the bottom. I find it a bit difficult to evaluate directly, though. I suppose if you see the central move as gaining 15 points in the moyo, the bottom one might count for 10-12, plus the effect limiting black which may be worth more.

This idea is mostly my feeling: expanding the center feels bigger than what I played.

I didn't evaluate points.

Position 2:
I disagree with you here. I think the game choice was better. With the marked Black stone on the board, however, Black should have been more aggressive and jumped to 1 maybe.

Here the normal follow up would be 1 and 3 I think. If White tries to cut instead of playing 6, Black plays the atari at 6 of course. Again this would find some actual use for the marked Black stone, which was completely useless in the actual game.

You over value sente (you do this fairly often in your games). Not only is 2 below small because of Black's strength in the bottom left, but 3 fixes Black's bad relationship between the two marked stones. Black does not need to connect these stones any longer. In the game, you wasted your thickness in the upper right when you 'forced' Black to connect these stones. Of course you should have separated them as in your variation in the game file. Your target should be to take over the top.

Position 7:

I think that you will be disappointed below after 8. ;-) The 1, 3 combo is not valid here so you were in more danger than you realized.

@ez4u:
Position 2: I see you variation, but why don't you like it compared to the game?

Position 3: I can see your point, and I agree.

Position 7: Haha :-)

Consider the two alternatives below. To my eye the first is preferable to the second. White's stones are all on the third or fourth line with no defects.

Agree about no defects, but there is endgame implication in the 'a' area, no?

In the other variation, white seems to have better endgame follow up.

Anyway, compared to the Atari I missed in the review from that last position you gave, this is subtle, it seems :-)

I guess the wall with defects has endgame issues on the other side, too.

I was feeling a little down, so I didn't study that much this weekend. However, I did make it to the Seattle Go Center last week for a casual game. I never played him before, but I guess he said he is Tygem 5d - that's a bit stronger than me, so I took black.

I don't remember the precise game, and the sequence is messed up near the end. However, I remember up until the middle game. The end result was a loss by me by 4 points on the board. So he played better than me, and seems a bit stronger than me at the moment.

Here's the game record, as I roughly recollect it, with a few comments.
