Thank you, Bill. I liked your comments.

I particularly like these ones.

This does seem much better, doesn't it? Especially with the low black stone on top.

I really like this idea. I need to avoid getting two weak groups, and like you said, it aims at a future invasion on the top.

Yeah, since I ignored him earlier, I think it's best to keep my money on the table. I chickened out, and he got benefit in both areas.

I played another game on KGS today, this time against 1k.

I should have lost. Lately, my "wins" are should-be losses. The beginning of the game was OK, but suddenly I made a mistake, and it was a disaster. At the end, I was very, very lucky.

Here's my review.

Problems.

Position 1

The game suddenly turned into a disaster when I played the marked stone. I was aiming at 'a', thinking that I could either attack the cutting stone, or cut at 'a'.

I didn't realize that 'b' was so powerful, and would be good to answer. In the game, since I went this route, I went all out and ignored 'b'. He captured me on the right.

Instead, I think I need to avoid disaster, and be more patient:

His stones are still not yet alive, and there is hope to reduce the bottom potential.

I think that the game is alright.

Position 2

I think that the marked move is an overplay. It would probably make more sense to play around 'a'. Just last game review, I was mentioning about avoiding getting into a scenario with two weak groups.

Still, I could not avoid temptation to play it, even though I felt it was bad. I wanted to make up for the right side. I was not patient enough.

Position 3

It may not have contributed as much to the disaster that resulted from the move in Position 1, but the marked move didn't create a good exchange for me, I think.

---

Overall, I think I was too rushed this game. He played kind of fast, and I wanted to play fast, too. I was too aggressive in the atari from Position 1, and aiming for the cut. I should have been more patient.

Again, I must remember:
Avoid having multiple weak groups.

Because of these too issues, I deserved to lose this game.

Some comments on the early play.

Main focus: Shape.

In the past couple of games you have made bad shape. Last time your play was heavy, this time it was thin. You shape was actually worse in the last game, but it still needs work.

Edit: Fleshed out a variation.

rat4000 · Post by **rat4000** » Tue Mar 31, 2015 10:19 am

Bill, I've got a question: you say "really?" on :w8:

, but it's joseki as far as I know and doesn't seem worse than anything else in this position. Why don't you like it? (Of course, the joseki responses to :b9:

don't include tenuki.)

Also, a question for Kirby: were you trying to avoid the Kobayashi fuseki by approaching immediately? If so, why not just pincer?

Kirby · Post by **Kirby** » Tue Mar 31, 2015 1:40 pm

Thanks for the comments, Bill. I agree about the bad shape with the group on the right. I wanted to avoid playing slowly, but your hane does, indeed, seem more natural.

Yes, the idea is to avoid Kobayashi fuseki - pincering is another option. This particular opening is one I've been trying, since I learned it from In-seong from the AYD. He talks about pincering as an option, too. But I like this one better.

However, I think it's correct to say that I've made a mistake - I should have not tenuki'd from :b9:

. I now seem to recall making a similar mistake from one of my AYD games, and I think he commented on it. It's not a part of the "main line" Inseong discussed, so I guess it shows that I haven't mastered this opening, yet.

Yeah, it's joseki, but what does it accomplish? What was so important that White did not respond to the approach in the bottom left corner? A three space extension on the right side? Really? That doesn't seem lame to you?

Thanks...

Anyway, Inseong doesn't seem to think it's lame (though he may have thought my tenuki to :b9:

was lame). Responding to the bottom left corner is fine, too. The strategy of ignoring the approach and approaching the 3-4 yourself is in order to play quickly. Since black plays first, it's black's job to "do something" (e.g. Kobayashi sets up a position for black). If white can prevent black from "doing something", and can play fast around the board, the komi will give him the edge.

rat4000 · Post by **rat4000** » Tue Mar 31, 2015 3:34 pm

Bill: I wouldn't play :w6:

precisely because I think black's approach is important. (Then again, apparently I'm wrong, if Inseong recommended it.) It just seems to me that after :w6:

is played white is forced to reply on the right -- rushing back to the lower left seems to be the worse of the two options.

Uberdude · Post by **Uberdude** » Tue Mar 31, 2015 3:47 pm

Kobayashi is good for white with large komi, let black do it ;-)

I'm not saying this at all. I am just saying that I am trying to practice an opening that Inseong taught. Part of this practice is learning what to do when the opponent deviates, and I'm still learning that part.

Even pros probably have different preferences in the opening. It doesn't mean that anyone is "wrong". What is important is to have a strategy. I think that answering the bottom left is a viable strategy. I also think that approaching the bottom right is a viable strategy. I also think pincering the approach to the bottom left is viable. What matters is how you follow up (and I could have done better at follow up after :b9:

).

Same thing is true for black. If there were a "silver bullet opening", all pros would play it.

The thing is, I don't think of :w8:

as speedy play. But apparently it is played.

is not something I would tend to play, so I have not thought much about it. But :w8:

cedes the initiative to Black, and is low, not challenging either the top right star point or :b7:

for the high ground on the right. The keima comes to mind.

In terms of speed, can White be satisfied with having prevented an enclosure in the bottom right corner? If so, then. . . .

The wedge looks interesting. It foils Black's plans to develop the bottom side. But, OC, it leaves the :w6:

stone vulnerable to attack. BTW, it is also joseki.

The three space pincer at "a" is also a possibility.

Kirby · Post by **Kirby** » Sun Apr 05, 2015 1:46 pm

Kids were napping today, so I played another game on KGS.

I was so lucky this game. There were two big reasons things went sour:
* I didn't read carefully, and just played moves a few times.
* Again, I repeated the habit I have of "going for 200%", as In-seong pointed out. Like other reviews I posted on here, I made multiple weak groups by invading the bottom left corner.

Anyway, here is my review.

I think this is silly, because it gives him, not me, the chance to make a good strategy. I think his pincer worked fine with his approach.

I should just play normally with either this:

With the sample variations I gave in the SGF, I think both of these are simpler, and have a fine result for white.

So of course, the following led to a bad result for me:

Why can't I just play in a normal way?

I think the marked move is greedy and hasty. It can lead to the situation of having two weak groups, given my weak two stones on the right.

I should simply strengthen that potentially weak group, while reducing black:

It's calmer. Of course, black can play 'a', and he gets a nice shape, but now I can feel more free to invade, since I no longer have a weak group.

I don't know for 100% that this is a better way of playing, but it seems better to me after the game. It's the kind of way I would never play during the game.

Potentially the game losing move, and perhaps trademark of my style these days. I should *not* go for making multiple weak groups. This potentially makes three weak groups:

It's impatient. I think this is what In-seong means when he says I go for "200%", but at a big risk. I'm trying to take all of the territory, enduring the fact that I might come under attack later.

Instead, again, I think I should simply strengthen my group:

Simpler, and there's still aji around 'a', anyway. Plus, his three stones in the center are not yet clearly alive, either.

Why didn't I play here?

There are several other mistakes I made, but these are the big ones that stick out to me.
