I'm not saying that k4 is unplayable. It's perfectly playable. If it is bad, which I believe so, it probably is less than half a point (for whatever scant meaning such metrics can be assigned to uncountable positions). When I say L4 is better I am striving to find the totally optimal moves, better than the mistakes pros sometimes makes. Yes those stats don't prove L4 is better, but 14 hits to 1 certainly says to me you should think about L4 seriously.


In the FWIW department, I decided to fire up my influence function and compare Black plays at K4 and L4. According to it, L4 is about 1/6 point better than K4. IOW, it is like a pro 4 dan play. ;) I should make such mistakes! :mrgreen:

I agree that 14 to 1 is not enough evidence even to say that pros in general have a definite preference for L4, and far from enough evidence to say that K4 is wrong. However, there is the general principle not to play too close to thickness, and I expect that that applies here. (FWIW, I tried my influence function on M4, and it said that it was even worse than K4. L4 make be the Goldilocks choice among these 4th line plays. :))

After the 4 corners black plays 5 for Chinese, a great move. 6 is a bit strange, if you add a move to a 4-4 so early it's normally a knight's move, and here f3 side is a better direction to reduce the Chinese opening. Then 7 is a bit unusual distant approach, but seems ok. 8 is a solid answer, but should it be a pincer? 9 is then a calm reply, though I feel 4th line would be better. Then 11 for 12 is obviously a bad exchange for black, and 13 for 14 is also somewhat bad for black if he is not the one to get the next move here. Tallying up those minuses is not so easy, but the duff 11 for 12 feels like the biggest sin.

I can see the similarity with this technique where you don't play the 2nd line slide because you fear a pincer or outside attachment, and want to avoid standing and getting the checking extension of a cramped 2 space extension, but there is an important difference in that black gets another extension, and also if white does hane on top at a black won't extend at b like in your shape but connect at c to grab the big yose and activate the corner aji. Also this technique is typically used inside a white sphere of influence (e.g. white lower right), rather than when black is developing his own moyo.

This permutation of moves seems rather strange. As for pairing the stones, the exchange of :w12: with :b7: seems good for Black. Why pair :w12: with :b11:? Why play :b11: at all? As for the exchange of :b13: with :w14:, we seem to differ. I think that it is a plus for Black as it is sente, preventing the Black descent. It also aims at the White weakness on the 3-3 point.

Suppose that we pair the in between stones as having small effect, and look at this position.

As against that, these pairings are plainly bad for Black. Which is worse, the Black loss from these pairings or the White loss from the above pairing? IMO, Black comes out a bit ahead.

IMO, this is roughly even, as discussed above. :)

Edit:

Even better, perhaps, let's start with this position as roughly even (taking into account Black's extra stone :)).

1-2 is bad for Black. 3-4 is almost normal, but I wouldn't say it's better for Black.

I don't know that 1-2 is bad for Black, considering that White missed this play.

@Uberdude:
I watched the video lecture again, regarding the position we were discussing. As I said earlier, In-seong did give the variation I provided as a way to play.

I listened to what he said, and basically he said, "as black, you can have this simple opening, and then when they invade on the right side, you can profit from attacking. If you like it, you can play this way."

Then he moved on saying something like, "If you don't like it, you can do this..." and he showed variations where black responded to the kick, white pincered, and they fought.

He actually spent more time on this.

So my feeling is probably that responding to the kick is definitely a popular choice, and In-seong brought up not responding as a simple option that you can consider if you don't like the pincer and complicated fighting.

In other news, I played two games today.

The first one was against KGS 3d. I took two stone handicap. Sometimes I can tell before a game that I'm not going to do well. This morning's game was like that - I felt that way before I even before I logged on to KGS. The reason is probably because I stayed up quite late last night celebrating something, and I felt a bit groggy in the morning. I don't feel that this game is worth reviewing, because I had a bad mindset going in. I probably should not have played it.

Anyway, that wore off as the day went on, and I played one of the AYD matches, this time against KGS 1k.

I lost this game, too. I made some ridiculously silly reading mistakes. I got lucky and it became closer, but then in the endgame, I ignored his threat to cut my groups. I should have just connected. Anyway, I didn't, and he killed me.

Here is my review:


---

I lost this game, and there were very, very, very obvious reading mistakes. But unlike the game in the morning, I tried to read deeply. Even a few times I made reading oversights, I spent time trying to read what would happen.

On one hand that's embarrassing, because even when I tried reading hard, I still made silly mistakes. But overall, I feel OK, because I prefer to try hard to read and make a stupid mistake than to not try to read at all.

Does that make sense??

I played the move above, because I thought the aji in the corner would let me cut his group in sente. But that may be a misconception.

His play was a big point. But now that he's made it, I should compromise. I can't get everything after he's played a good move.

Instead, I think I should just play this:

Derrr... I can do nothing but cry.

Obviously this doesn't work. I am falling apart, because I am in two groups, because I resisted his good move. If I was so worried about the move, I should have played there first, but I didn't.

This is a disaster.

I cannot see a good variation in the top left for black, so it's already bad because of position 1.

But the fact that I didn't see that the move above doesn't work is... Ridiculous.

But I was only checking whether 'b' would work for white. Since black had enough liberties, I could then play 'c' and win, right?

Of course, I forgot that the first sequence I read was no longer valid since :w8: is present.

Ug.

So instead, I should play this:

Obviously, I should play at 'a', instead, because that group is bigger than white's top right group. He answered, but if he played at 'a' after that, I'm just dead bigger than he is.

I thought the game was close, so I needed to grab big points before he did. So I didn't connect at 'a'. Clearly, that's better, though.

Why didn't I connect? Why didn't I connect? Why didn't I connect???

---

Learning Points
1. When the opponent plays a good move, or gets a good position - I *cannot* get as much as usual. I must learn to acknowledge his move, and play properly.

2. Avoid obvious reading mistakes.

3. Connecting is good :-)
---

By the way, I still can't read a way to kill or get ko with this shape... But I feel like I should be able to. No?

I often have a sense of how I'm going to do in games on a particular day as well, before the games even start. It's much more frustrating when I am playing in a tournament that day, and pretty much know I'm going to go 0-4 before I start, but the reverse is always nice. I do wonder if it is to some degree a self-fulfilling prophecy, however. If you've convinced yourself that you're going to lose anyway, maybe you just phone it in for the game/games so to speak?

Probably, skydyr.

Sometimes on such days, I recall being in the middle of the game thinking, "Why am I not trying harder?", but usually, I just continue :-p

My advise you to play game that is 끈적끈적.
maintaining balance and grabing chance is the key to play such style.

also, I see that you have reading strength but you have to connect series of good moves into one long sequence.
I think you will need to read less to improve.
Your reading was way too complicated (and wrong i think).
selecting simpler variation will make your mind clearer and result less mistakes.

just a thought.

Interesting. I'm guessing that my style is not this way now, right?

I don't quite understand what you mean with this part, above.

It's the first time I've heard the advice to read less. I guess you are saying that reading less is better than reading incorrectly. I suppose that's a good point.

Looking at google translate, I get "sticky" for 끈적끈적, but this doesn't seem to make sense to me. Could you describe what this style looks like?

It's the first time I've heard the advice to read less. I guess you are saying that reading less is better than reading incorrectly. I suppose that's a good point.


I can also take away this: Reading should be impartial. I often want something to happen and thus cloud my reading or steer it into ways which support my goal. Even if I have to admit, that my goal cannot be accomplished, I often return to the position and read it again and again.

Could be just me, though ; )

Looking at google translate, I get "sticky" for 끈적끈적, but this doesn't seem to make sense to me. Could you describe what this style looks like?


Sticky is the correct translation. I saw an article here[1], which is about pro player Kang Dongyun. It says that his go style is famous for being "끈적끈적". He'll often get into a disadvantageous position, but he pops back up, and turns the tables. I think that's the "stickiness" (the opponent can't push him down for good, since he keeps popping back up). It says that Kang Dongyun's weakness is the opening, but because he has 끈적끈적 style of Go, he can often win by making these kind of turnarounds.

From my own perspective, maybe a good English word to describe this would be "tenacious".

That being said, maybe I should study Kang Dongyun's games. If I am to have 끈적끈적 style, maybe I should see more of what that looks like.

I played against KGS 2d today. I won, but it was really lucky. It should have been capturing race, and I think he could win, maybe.

But anyway, he just let me connect, and he died.

Here's my review.

It doesn't give white as much pressure, but as white is open on both directions, I don't think I can give much pressure, anyway.

I didn't read out that I could kill him - it just looked like a chance. So, I bet the entire game on trying to kill him. If I failed, my stones could die. And I think they probably should have.

Instead, I should play calmly, and reduce the center. He has about... 45 plus what he gets in the center. I have about... 40, maybe.

So there's probably still a good chance if I play good endgame.

This is an example of where I could have tried to kill, or tried to make it close and play it out. Sadly, I chose to bet the entire game on killing. It happened to work, since he gave it to me, but it probably shouldn't have.

Am I too single-minded towards the center?
I don't like 'a' because it just takes territory and has no follow-up/goal. Maybe this situation calls for a move like that, I don't know, it feels rather passive to me :scratch:
