Hi pak0,

good. Proper shape and move.

:w8:

too far. F4 or F3 is better.

:b9:

good. Good extension and shape.

:b11:

good ( but you missed the follow up at :b15:

... )

Study what happens if you cut instead at D3.
( Then if W ataris C3, you drop to D2. Study what happens next ?

Study the follow-ups. )

You resigned with 101
after a self atari at :b99:

and an unreasable cut at :b97:

Your frustration was clearly noticeable in these moves so the question is "where does the frustration come from".
I believe it is rooted in a misconception of what is yours, or "territory". When the opponent invades what is yours, you are hellbound on punishing him to the point of devastation, which obviously backfires.

In the opening there is no territory. Even a low enclosure is not fully secure. In the opening you put a stake in the ground which evolves into a sphere of influence. When the opponent invades it, you will take profit under any of these forms:

1. kill a few stones and solidify your groups
2. kill a few stones and solidify that area into territory
3. chase the group and build influence to the other side
4. chase the group and make territory on the other side
5. something else, like solidify your positions while the opponent is left with the burden of a big weak group

only rarely does the position allow or call for a wholesale kill.

In this game, n° 4 happened but it didn't satisfy you because you thought the left was already yours, while chasing the top. So, at :b81:

I think you thought you just "defended" your territory, while you were actually making territory in the process of attacking, which is a kind of profit.

Now, while a move like :b81:

should bring the joy of profiting from an attack, in this position it was perhaps not the right choice because your own chasing group in the middle was weak. See the game for an alternative move, maintaining the chase but "giving up" the territory you thought was yours. In fact, while White may seem to be able and destroy that "territory", he may still die wholesale.

Correct me if I'm wrong and if this is not at all what you were thinking.
If you want sth tactical to chew on, look for a tesuji in the resign position to connect your top to the top left or the centre.

A few comments.

Edit: Added a couple of variations.

@Ed: I will look into it, this shape recently showed up quite some times in my games for no apparent reason.

@Knotwilg: I know that you often don't attack to kill, but for profit. The problem in this case was that I could not see where my profit was coming from, so the only alternative that I saw was to actually kill something.

@Bill: Thanks for the variations, seems like I could have gotten a lot more if I would have been less attached to my stones on the right. I though I got rid of the habit of not keeping everything alive, but apparently not. Also nice to see the punishment on the bottom right, I knew something was there, but I couldn't figure it out in my game.

Thanks to all who continuously (or sporadically) give me reviews and advice, I promise to play a game sometimes that incorporates all of it :salute:

Some time, if you're bored out of your wit,
re-embrace a bit the vastness of Go... here.

So another game, I didn't know any of the joseki and my weak reading did the rest. All in all I feel like I got kinda stomped, so there probably was a rather large problem. Any help welcome.

Play at S-02, threatening R-05.

:b23:

The crosscut gives options to White. Pulling back to L-04 would leave the two White stones weak.

:b31:

Takes your eye off the ball. The fight on the bottom side is urgent. True, the Black stone on K-03 is weak, but the three White stones next to it are not yet settled. Even if you give that stone up, you should get something for the sacrifice. A running fight is another possibility.

Where to play is another question. Without the G-03 stone in place, J-04 is a normal attack. But it does not look so good in this situation. Perhaps the attachment at G-04 would be good. It has a diagonal relation to the K-03 stone. (E. g., via J-04 and H-03.) G-04 also looks at White’s weak corner.

:b31:

-

Haven’t we seen this before? Black is over-concentrated.

:b45:

Timid.

Makes a large moyo, but allows what comes next.

:b53:

Very painful.

I'm not anywhere near as good as most of the other players on this forum, but here is my humble attempt at analysis. I hope it helps.

Since I did this mainly as a learning exercise (I got to look up a couple of josekis! and figure out the best move to seal off an invasion!), I also included Bill Spight's comments above -- they are his, not mine -- and played around with the variations he recommended to see if I could get them to work.

I apologize that I am not a very good player, but I couldn't resist the challenge.

Hi Sam, I never use the SGF link feature.
I always embed the full SGF text directly in a post.
Did you check that your SGF link worked after you posted 204 ?
( As of now, it's not working properly, yet.

)

Posted: **Thu Oct 16, 2014 6:25 am**

Ed,

I did check it, and I checked it again, and it worked both times. However, since you are having a problem, just to be safe, I re-uploaded and re-linked to the new file. It is still working for me, but obviously this doesn't mean it will work for you.

Please hit F5 on your browser and let me know how it goes.

Thanks!
Sam

Work on that reading! For example, at 88 White plays the atari at 1 below and Black rescues the single stone with 'a'. Disaster follows.

It is not so much 'reading' as having some feeling for what matters. If Black simply captures the marked White stone with 2 and 4, White is in big trouble. The point is that taking the marked Black stone alone will not allow White to live, while taking the marked White stone leaves behind life at 'b' for Black. The best White can do is play to start a ko with the hane at 5. However this is a very easy ko for Black who can be happy just to live in White's area.

Responses to Sam.

Edit: Corrected a variation, the one that avoids a ko.

Edit 2: To show my misread.

Posted: **Thu Oct 16, 2014 11:53 am**

So many variations =). Thanks, I already skipped through them and there is a lot to see, gotta take a closer look during my next study session.

@ez4u: Damn, the stuff you point out always seems so obvious it makes me question how I even managed to miss it during the game x.X
On the reading: The problem I have with it is that for improvement/time spent it comes out as one of the worst things, study wise(at least that's what I feel).

Anyway, enough of the loosing, I finally reached a new milestone. Since tygem hates me for some reason I decided to pay a visit to KGS again, and I just beat an SDK in an even game for the first time. (Also it contained a running fight in which I did not die horribly, which is an accomplishment in itself)

It is not so much 'reading' as having some feeling for what matters.

That's a very important point. Reading is so much more than the calculation of variations.
