One more on my quest for serious games. :blackeye:
My opponent admitted later that he(?) "just fooled around" at some points. Still good enough against me. I rather enjoyed this game, instead of attacking aggressivly to win, he(?) just played better. :)
But i often can’t distinguish between good play and “fooling around” that just works due to my little experience. Some comments on that would be cool.
But anything will be mostly appreciated. :)

Afterthought: If someone prefers a file without my own review and variations, i will gladly provide that.

Hi Hrab,

:w22: Strange.

:b31: Cross-cuts are notoriously difficult. That's probably why W played :w30: .
However, there's a basic shape here that's very nice to learn.

In your :b31: variation -- let's just ignore W's cross-cut stone ( :w30:, at R4 ) for the moment.
You made the wrong atari. Can you find the correct atari.
( There are no doubt many more mistakes in the fundamentals after this,
but to me, to learn this atari is worth this game. :) )

Many thanks Ed :)

Finding the atari was easy, once you told me. I totally agree about the importance! I had similar situations before, though without the crosscut, and just blocked below (my opponents too). I’ll try out some variations with supporting white stones in the corner to stock up my toolbox.

Do you mean this one?:

It will take some time to work through this. :study:

And many a thread about it! And maybe even more opinions on the definition ;)
A bit frustrating for me, since i like a structured approach, but for the moment i think it’s best to keep on playing, reviewing, getting reviewed.
Though "First Fundamentals" looks very tempting …

I’m not sure wether you are
a) pointing at the obvious: ladder,
or
b) i’m thick as a brick. :scratch:

In case a) thinking of it as a ladder probably anchors it better in the mind.

I think Bill was hinting that black can do better...

Yes, I was hinting at the ladder. Sorry, I didn't realize that it was obvious to you.

Nothing to feel sorry for! I still miss obvious points frequently, and sometimes i’ve just "got tomatos on my eyes" (don’t know how to say that in english :) )

My previous post shouldn’t sound ungrateful or grumpy at all. I was just putting down my thoughts quickly without thinking about how they might sound without gestures and facial expressions.

I hope i didn’t step on your toes and if so i’m really sorry!

But replaying it in the diagram i didn’t check it properly.
Still my blind spot: future atari

Black can still do better.
Bill mentioned white's liberties. Why? :study:

Now i got it, there is a ‘real’ ladder ( :b5: at o2), not just a ‘kind of‘ ladder :!:

Many thanks to both of you for talking me through it! :bow:

Yeah, the White string is a goner. But a) you took an extra move to dispatch it, and b) it still has aji. White can threaten to save it.

  • In Chinese, there are actually different descriptions for the two starting moves (a) and (b).
    This distinction seems to be missing in English ;
    not sure about in Japanese or in Deutsch.
  • Read as far as you can. ( Re: missing the ladder; post 3. )
  • Liberties, liberties, liberties. ( Posts 4, 10 )
