In the game, I played 'a' with the intention to pressure the marked white stones.

I think it would have been simpler to just play 'b'. It gives me more territory, and his influence is not great.

I agree. But I'm interested in the whole thought process from

White has concentrated on the left side. This might be the good moment to try to force with the marked stone. Later on it seems Black mainly succeeds in starting a fight where White is strong. And, as you say, the clamp sequence doesn't help that plan. Either B9 or C9 might be good, depending on the rest of the position.

White has concentrated on the left side. This might be the good moment to try to force with the marked stone. Later on it seems Black mainly succeeds in starting a fight where White is strong. And, as you say, the clamp sequence doesn't help that plan. Either B9 or C9 might be good, depending on the rest of the position.

I like this idea. I played this kind of move in the game after I gave white a strong wall, while I could only play 2nd line moves in return. Definitely better than the game.

Today I am not reading well. Maybe because of work. Either way, I played a low quality game.

I should have lost for sure, and almost resigned. I threw away the game, but I guess he gave it back to me.

Here is a brief review.

Kirby · Post by **Kirby** » Wed Dec 10, 2014 1:59 pm

Here are some thoughts on a few notable positions in the game.

Position 1

I attached as shown above.

I don't really like the shape with 5-5, but it might be better to go faster like this:

Then approach as shown, or play 'a'. I think it's faster, and better than in game... But during the game, I never like to play this way, since I have bad experience with the shape in the top right.

Still, probably better.

Position 2

I played as above. It might be ok, though a friend recommended this:

It's not bad this way, I guess. It's a better shape against the top, probably, though black's shape on the right is better than in game, I feel. Kind of a trade off, but this way doesn't seem that bad.

Position 3

Here, I made big mistake. Potentially game losing mistake. I didn't think of him attacking my two stones, and only thought of counter attack at 'a'. So in preparation for that, I imagined the following type of attack:

But this is too aggressive, and probably naive. Of course, he didn't play along, and I continued to make mistakes.

At this point, he definitely has local advantage.. So I should suck it up and play a hane underneath at 'a'. It feels weak, but my position is bad locally, so I should just be safe.

Bumping might be another option... *maybe* it'd be safe to tenuki. Still risky, though:

In the game, I insisted on keeping him cut with 'a'. But more important than some wild attack attempt is to keep my group strong. Even if he connects with 'a', I don't get attack, but can continue to play elsewhere. It's not the end of the world.

After move 78, above, I've lost the game, basically.

He or she happened to let me win, but it's not worth reviewing that, probably, because the quality of game is low to get to that point.

---

Some takeaways from this game:
1. Don't be too aggressive. Think of what the opponent can do to you instead of only trying to attack the opponent.
2. Read better. I should have read the result of the capturing race much earlier.

I guess those are the main points I learned - not very many, but I was too aggressive this game to play with high quality.

I hope that my next game is of better quality.

For

did you consider double-hane directly, without the inside atari? The atari gives B an instantly living shape, so should be avoided if possible. The double-hane without atari looks like it gives B much more difficulty. In fact, I do not see an acceptable continuation for B.

I did not consider it. In fact, I played the inside atari nearly automatically, maybe out of habit. Looking at the game record, it looks like I played in 14 seconds - I don't recall thinking about the double-atari during that time. I think that your idea of double-hane is more interesting.

What makes me feel bad about this is not the fact that I missed the double-hane, but rather that I remember the feeling of not even trying to consider an alternative. Sometimes during games, I consciously consider alternative moves, and when one line does not work, I try to think of some sort of preparation to make it work.

What is upsetting is the conscious feeling of not having bothered to read precisely. This definitely occurs periodically in my games, probably more often when I am physically tired. I think that, in order to improve, I will need to overcome these mental shortcuts.

And thank you for your suggestion of double-hane. This shape occurs often, and I will try to make sure I at least consider both double-hane along with inside atari when I see the shape. It certainly seems worth considering here.

And if you only consider one move it should be the double hane, as it's usually the better move

Btw, I think your hane outside for position 4 was best, attach for 1 was fine, kick of 2 maybe better but black didn't take advantage by extending into corner, and pincer of 3 was ok but your toothpaste squeezing plan wasn't good. That missed double hane was a bigger mistake than the ones you identified.

Thanks for the feedback, Uberdude.

Regarding double hane, I agree it's often a good move. For example, on empty board, it's no threat if white plays

Perhaps the reason I felt inclined to do the inside atari was because there was a nearby opponent stone. I recall having bad experience in the past when nearby stone made it problematic that white could perform the atari on the double hane first. For example:

The example here is a bit contrived, but anyway, when you do the inside atari first, you can guarantee cutting apart the stones.

I think because he had nearby stone, my first instinct was to guarantee cut, but as is definitely clear, this only helps his eye space, and is not good in most cases.

I think I will need to consider double hane first from now on. But I can understand why it wasn't my first instinct in this case - I've had past experience where it mattered when the opponent cut first.

I agree (though, I'm still undecided about whether attach is better or 5-5).

I don't quite follow. Do you mean this sequence?

Basically, I agree, because there is still aji for black to make something work with his group on the right, and I've damaged my stone on top significantly.

But even thinking I could get to this position was naive.

The toothpaste referred to the 6 for 7 exchange, making a broken shape. Now if that allows the cut of 8 to kill unconditionally and there is no effective black sacrifice I can accept it, but my feeling is to cut with 6 directly and only make that bad push if you need it, or maybe play 6 as kosumi one point lower.

Ah yes. Seems correct.

I played a handicap game today. I gave my opponent 2 stones. The game was a little sloppy, I'd say - at least I feel that way.

I feel like I gained a bit of a lead by the middle game, so I didn't feel pressure to play precisely after that. I still should have, though.

Here's a brief review:

Kirby · Post by **Kirby** » Thu Dec 11, 2014 1:34 pm

Here are a few of the positions where I feel I could have improved.

Position 1

The move above is one that I like, but it is really more suitable if I have white stones on the right, too. I like the move, but I can't say that it's the best for white here.

It's probably fine to either answer:

Probably both options are fine, depending on whether I want to have influence or get territory early on.

Anyway, the kick might not be the best here - though I love that move

The double approach was because I thought the 3-3 was too easy and ended in gote. However, he could have made a decent position on the left side with the way I played (though it might be better for black if the top left was 4-4 stone instead of 3-3).

If I just go for 3-3 here, white gets sente, and maybe can take advantage of my kick, but black doesn't have potential for something that big like he did in the game:

Black's position is nice, but maybe it's a result of my playing the second line move in the bottom right to begin with.

Also, he could have still played this way in the game, too (or play in the left, as I had feared).

So from this, I conclude that the marked white move, above, was bad. I didn't have a good position to use it effectively, and it becomes a burden later.

This was too sloppy. As shown in the SGF variation, there is aji for black to hane, and I don't like that aji.:

Now that I've given black a wall, it's probably good to split on the top as in the game, but perhaps the problem comes a bit earlier:

If I play as above, I'm less cramped if black approaches from the top, and still have room to extend if black approaches on the bottom.
For example:

It's a little small for an extension, but perhaps better than playing so close to black's influence on the bottom left.

Simply, the marked white stone is wrong. I should just approach as follows:

It would have been better since his kick and pincer (as in variation in SGF) will make white have more pressure.

From this game, I learned:
1. Do not play a move that doesn't work well, even if I really like it (the 2nd line response to his approach to the bottom right 4-4 stone).

2. If I reject a variation (eg. 3-3 in bottom left), make sure the alternative produces a better result. Just because I don't like variation A does not make variation B better, unless I've thought about it and concluded that.

3. Do not ignore aji my opponent can exploit, even if I am white in handicap game (eg. his hane on my left side stones would have been annoying, as described in the variation).

Basically, these three ideas come down to one: Play precisely and with a plan, ensuring that my plan produces a good result.

I think it would be consistent to jump out to F5 with

. Then the footsweep stone would have some attacking meaning.

makes sense in the overall position (though

should be more like F16), and so I think

could be one line higher. I would definitely prefer

at E12.

looks weak: play C10, Black B10, and then B14.

is another wedge and I'm not sure about the placement again. Black should clearly approach it from the right.

If this was at R10 and Black answered at R15, I'd say White could just play N3 and be happy. Black has just made tight shapes.

is good, and White's main worry in the game is what happens after Black C10, White B10, Black B11.

Thank you for the review, Charles. I especially like your comments regarding F5 and R10. I totally agree.

I played a KGS 2d today. My opening wasn't great, but I read out a sequence I was proud of. I feel like I gained a lead then.

But then I blundered in attack, and he effectively created a moyo in the center. I feel I was about 10 points behind, then.

He was generous, and happened to let me live, so I had a chance. But I couldn't pull through.

Here's the SGF with my review:
