Post subject:  Please critique my game? 18/4/16

Is :black: 69 unreasonable because white was able to push above and cut later?

Are :black: 163 to :black: 167 unreasonable because of possibility of :white: S8?

Please ignore my :black: 241 'misclick' that could have lost me the game.

Besides these points are there other moves I could improve upon?

Thanks in advanced for any comments.

Hi pragmatic,

:b13: Let's think about this move for a moment.
Maybe you have seen the following (common) sequence:

[go]$$B
$$ | . . . . . . . . .
$$ | . . . . . . . . .
$$ | . . 1 . . . . . .
$$ | . . . . . . . . .
$$ | . 3 . O . . . . .
$$ | . . . . . 2 . . .
$$ | . . . . . . . . .
$$ | . . . . . . . . .

Was this (partly) why you played :b13: ?

Hi pragmatic,

:b13: While you're pondering the question,
notice that your lower left corner is not the same situation as the above common sequence.
Rather, it's like this:

[go]$$B :w2: Tenuki
$$ | . . . . . . . . .
$$ | . . . . . . . . .
$$ | . . 1 . . . . . .
$$ | . . . . . . . . .
$$ | . . . O . . . . .
$$ | . . . . . . . . .
$$ | . . . . . . . . .
$$ | . . . . . . . . .
$$ --------------------[/go]
Notice also that :w2: (in post 2) is a good point for White.
Given these, can you think of another idea for :b3: here ?

Hi EdLee,

Yea, I pondered about using a double approach instead but wasn't too familiar with its continuation. I thought maybe white could choose which side to give me in that case and could destroy the other side, but I might have over worried.

Thanks for bringing this up. I shall study the double approach continuations a bit from page 137 in The 21st Century Dictionary of Basic Joseki Volume Two.

I see; good, so you considered it but rejected it.
That's OK. Next time, try a double approach. :)

Hi pragmatic,

:b17: Did you consider any other points ?
Did you consider J3 ?
:b19: Did you consider any other points ?
Did you consider F14 ?
:b27: Did you consider any other points ?
Did you consider D9 ?
:b31: Your shape is very thin; how much of the fighting did you read ?

:w32: W has to read how to cut :b31: and all the subsequent fighting.

:b47: Nice, big feeling.

:b49: Good fighting spirit; did you consider other moves ?
Did you read N11 ?

Hi pragmatic,

:b53: Did you read other options ?
Did you read N13 ?
:b59: Why ? What was your reading here ?

:b75: Why ? What was your reading here ? What's wrong with the hane ?

Hmm... good point, then white would have to get another eye in the center while I attack him/her to get some sort of profit/influence.

I did, but I didn't want to let white get profit by playing F16 etc. while I don't have some sort of eye space while white D12 has room downward for some sort of extension.

I considered moves like M4 to break the ladder, but thought it would be a hassle to always keep the ladder in check. I did not consider D9; seems like it's also useful for changing the direction of the ladder while providing some support to the framework.

Not much to be honest. It was kind of a move on instinct during the game.

I considered a kosumi at N12 after making the move. The game was my first one on IGS and has a new time setting which I am not used to, so some of my moves may seems a bit rushed. N11 is interesting, I would have been too afraid of being cut before if I played this kind of move, but I guess it can be a good move sometimes now you mentioned it.

I might have, but at that moment I wanted something kind of forcing, but I guess if W Q14, I could have B Q13 after your suggested move of N13?

Fear of getting cut into two groups.

I wanted to cut at B O10, W P10, B P9, but was afraid of the white stone at M10 atari my the 4/5 stones in the middle and cut my center group into two.
