A few variations.

ez4u · **#22**

In your previous game you wrote that you are studying the san-ren-sei. In that case I think your :b7:

at "a" is already off the mark. Extending down the right side in front of your san-ren-sei and your opponent's shimari is clearly bigger than the bottom. You should be expecting something like the diagram below as a thematic development of the san-ren-sei. If you are not comfortable with this, then you should have already played :b5:

at 6 IMHO.

Hi oca, you hit the nail on the head.
The assimilation, or understanding, is a continuum and a continuing process — it never ends.
Along the journey, we occasionally are rewarded with Eureka moments. Together with long dry spells.

About your :b19:

in the denizizmir game: I struggled with this kind of mistakes
for quite some time. And I know people (even at 3k) who have been playing for 30-40 years
and still don't understand it.

Enjoy.

Hi Bill,
Thanks for your variations, I like :b17:

at O10 and your absolute :b19:

was my first instinct... but then feared :w20:

as I can't read the whole sequence (I can't read the whole sequence of "a" either... but I was feeling that I can connect the right side and the top more easily, the game just showed me that was not true.)

Hi ez4u, Sure !, this is exactly what happenend in my head... a confict between playing a sanrensei and that takamoku that I wanted to reply....
I choosed the sanrensei because I was thinking that I could approach takamoku later... and of course ... wrong

when my opponnent just played the following enclosure

I was thinking "oh no... I wanted to play there later later... but you won't have the whole bottom !" and obsessed by the bottom and played :b7:

at K3 like if that was the only possible move...
A more peacefull thinking like "oh... you want the bottom ? just take it... I can still (try) to do bigger at the top" would have been better for me....

To comeback to the sanrensei, at some point in the game, I remember that I was thinking that this game doesn't looked at all like a sanrensei game... so I should have done something wrong at some point...

I think this sequence also killed it...

hane at the head of two stones in not so great here I think...
:b45:

: Not sure about this one but a cut at "a" may be a least dangerous...

Finally, to come back to your diagarm, I would say I like your :b9:

, I never considered this move but I like the way it looks...

Thanks Edlee, I wish I can apply all these things I have read... but that's not how it work... patience and tenacity are my best friend here I think.

Also my balance between playing / learning was too oriented toward learning, I'm happy as I find more time for playing these days...

oca · **#25**

Hi, two games for me yesterday ! I'm black in both game.

Here is the first one, no san-ren-sei this time,

I think I'm still doing the same errors...
- :b21:

: S5 to separate white is better I think.
- :b41:

to

way to small is it ?

But ok, I won that one so I'm happy, and I somehow managed all these invaders at the end :batman:

, an exercise that I'm not really strong at.

I'm more interessed on game 2, an 8 stones handicap, where invaders killed me !

I handeled white 263 with success, but failed to reply to the final invasion at move white 279 and finaly lose the game (I think 282 at S6 may save the group ).

I'm still happy of my seki at 228, which finally was not a seki anymore...
I had a lot of fun in that game

Any comments very welcome.

Hi oca, game 1:

equally ridiculous.

There is only one move here.

strange shape. What's your plan if W ataris Q17 ? (Did you read W Q17 atari ? )
:b41:

is not small, but wrong technique.
Maybe wrong plan: what are you trying to accomplish here ?
Can you find the correct move, instead of your :b41:

?

bad shape: W hits the vital point, the elephant's eye.
See Post 5 again: same note again.
:w72:

bad habit. Correct local move is just connect E2.

bad habit. You should have tenuki'd.

very bad. See Post 5 again, same note again.

Hi Edlee, thx for your comments !

:b15:

is just a miss click...
:b17:

ok... I will study that position
:b19:

hmm I suppose S5 is the only move... At least I considered that move while playing, but for some obscure reasons, I remember very well that I was seeing the game like that at this point :

I considered :b19:

at "a" but I didn't like it as I was thinking that it did not helped that much neither the bottom nor the top/right. so I choose to help the top/right with both :b19:

at "b" and then :b21:

at "c" ... but I agree that was not a good choice... Next time I will separate

EdLee · **#28**

Hi oca,

Game 2.

:w29:

bad habit: correct is capture directly. See also :w72:

in game 1.
:b32:

wrong local move. Correct local move is just descend H2.
:b34:

wrong for 2 reasons: locally, correct move is just connect solidly
at H2 (which is where :b32:

should have been, directly).
Globally, it is too small. :w33:

is gote — you should have tenuki'd.
Same bad habit as :w72:

in game 1.
:b36:

no fighting spirit. Connect at J3 and fight!
:b40:

What's the meaning of this move ? It's almost a pass.
:b48:

almost a pass.
:b52:

almost a pass.

This is a 8-stone game. You quickly passed 4 times: :b34:

,

,

,

.
Only 4 more passes, and you would have given all your handi stones
back to W.

is gote. You are super thick here.
:b56:

no need to connect, but not a big mistake at your level.
:b58:

almost a pass, your 5th. Why not reply at C10 ?
:b90:

ridiculous. See Post 5 again. What's the correct local move ?

Hi oca, you're welcome.

One key thing for us to improve is to realize where our thinking is wrong.
Maybe now you start to see it for the local situation.

Uberdude · **#30**

Don't forget to think about the basics: connect your stones, separate your opponent's.

If you tenuki after 263, what can White do? If answering is not necessary, we can't call it success. ;-)

You are correct that 282 at S6 would have left White unable to continue. Black would have more liberties than White. :tmbup:

Your comment on 228 isn't clear. Do you realize that you killed the corner with 242? :tmbup:

Hi Uberdude,

"Don't forget to think about the basics: connect your stones, separate your opponent's."

Sure, I will try to improve that. I think 9x9 is also a good exercice for that.

Hi ez4u,

"If you tenuki after 263, what can White do? If answering is not necessary, we can't call it success."

That's just I usually die at each invasion, but that's right 246 was needed... so that's more a fail in this case ...

"Do you realize that you killed the corner with 242?"

Of course... Not... :shock:

That was seki for me... I was thinking that 6 was unconditionally alive... but not so in the corner... as you showed in your post.

@Edlee

Lots of things for me to look at

...
Let's start with that "connect/separte" topic.

So in Game 1 :

65 - bad shape: W hits the vital point, the elephant's eye.
77 - very bad. See Post 5 again, same note again.

I can see the separation and the elephant's eye, but I don't see what would be better :scratch:

...

Tryed that but that don't look any better to me...

Now about these moves :
73 - bad habit. You should have tenuki'd.
91 - same bad habit as

I tryed to avoid that situation :

Good observation.

There are two different issues here: (1) recognition; (2) finding a better move.

Please see also posts 41 and 43 of this thread.

Currently, the recognition phase is to help you see that (a) is the only move.

I showed that situation to show what I was afraid of if I was black... white to invade and live [edit] or at least try to...[/edit]. but I just saw that :w1:

doesn't work... white should at least fix "a" first...

Actually white doesn't need to fix "a" first: those stones are no longer important and can be sacrificed: helping the invaders is a much better idea.

Btw it's interesting that you feared that 1st line invasion of white as it's not something I would even consider. I'm not even sure cutting it off is a good idea for black: it might be better to just fall back or tenuki as it's small.

Note in your variation you played hane with 77 at 78: that doesn't work as white cuts. I hope you can see that just extending is BRILLIANT for black. What is white achieving with this crawling? Trying to win five-in-row?

Something to note is your n4 q4 stones are weak and vulnerable because you missed the hugely important separation at s5 for move 19 so getting them connected and strong like this whilst white crawls along the 1st line is great for you. That 1st line move is an underplay for white and he could do much more severe things like L3 invasion to attack n4 and maybe even g3 cut later or h3 peep.
