From post 45:

As for tsumego,
(1) books are not really practical
so I try doing 10 problems at goproblems.com each day but
(2) it doesn't seem to be doing much.
Could you elaborate a bit on (1) and (2) ?
( Curious about your experience; thanks. )

Hi EdLee,

As always, thank you for the comments.

For :b23:, do you mean this move is fine if I follow with P7 or P6? Or do you mean that I should play P7-6 to save what I can?

For :w28: at R3, I thought of that

so I guess I should still work on that cut. I started reading lesson in the fundamentals of go once again and this cut actually appears in the begining, page 28 dia 4 (or at least I think this is the same)

As for your questions,
(1) For tsumego books, I actually only have a printed version of cho chikun's L&D in A5 format and it is not so handy to have with me. But I do this at home now
(2) At the time I did not see any improvement. I know consistency is key but I feel I learn more when I cram a lot of tsumego at once.

Now for the lost game of the day. It was again a 5kuy on kgs, I lost by 3.5. I see how I could have won the game but I don't see where I lost my 2 stone advantage.

Hi Laerthd, You're welcome. :)

No. I don't know how to evaluate :b23: . But the combo of :b23: and :b25: seems strange to me.

That's not good enough. The solution was already included in post 60. :)

I can see it's kind of big.

Hmm. Good question. Not easy to answer. :)

Hi Ed,

Oh, they look similar to me. I mean not exactly the same but I don't know, the capture works the same no?



Today's game, against a 7k on KGS. I should have lost but he got distracted at the end so I won.
I lost because I could not find how to deal with the upper left so any comment on that (and the rest btw) are welcome.

I was looking at the black group in both situation.

To me at first sight the :bc: are basically the same with respect to capturing :ws:
But looking at it a bit more closely:
in Kageyama it's black turn and in your diagram it's white
in kageyama :b: is allowing the capture and in you diagram it's the edge

So maybe not that similar ^^'

Hi Laerthd,

Game v. kwinin,

:w18: OK.

:w20: o4, etc.

:w22: R4.

:w26: Bad habit if you're not going to cut -- just :w28: directly.p

:w38: S8+Q8 sitting there, to fix your shape.

:w42: Did you miss S8 ?

Thanks for the comments Ed, I think I'll learn something there because I don't really understand your moves.

Quote:
:w20: o4, etc.

What do you mean by that? Is there a typical sequence here?

Quote:
:w22: R4.

Is this because with Q3 I lose sente and will never really get the opportunity to make my wall useful?
I played there because it was facing the largest side.

Quote:
:w26: Bad habit if you're not going to cut -- just :w28: directly.

I was trying to create weaknesses. I thought it was pretty good because next he bumps his stone against mine and it gives me endgame no?



For my progression now! I manage to reach 12k on IGS tonight (actually I already reached it but went back to 13k directly afterward) so that's cool :)

Hi Laerthd,

It's because L3 area is nicely open for B after the corner sequence.
Quote:

Good that you had this reason for :w22: ;
but now you know, in this case (and others), that reason alone is insufficient --
one must look at the whole board and other factors.

No.
  • You reduced your own liberties ( you never know when you'll need it! ) ;
  • You removed S5 as an option for yourself (see diagram below) ;
  • If you don't cut, you give B a chance to fix his weakness ;
  • B would not play R5 himself right now (too slow), so there's no hurry for you to play it, either ;

With :w26:, you removed this :w1: peep from yourself as an option, in the future:

( Pushing on top directly at :w28:, instead of :w26:, also removes the same peep,
but you keep the one liberty. )

Hi Ed,
Ok I take not to play R5 from now on.

Today's game is against a 10k IGS. My proudest win so far. Not many comment for this (but of course they are always welcome), I just wanted to share the game.
I guess the lesson to take home here is that reading is important.

Hi Laerthd,

:b12: B2.

:w13: What was your plan if W haned D7 ?

:b26: Why not cut and fight ?

:b42: L4 is the big fish.

:b44: F8.

:b48: K7. L4 is the big fish.

:b56: - :w57: This exchange... :-? Maybe L8.

:b64: o2 or P2.

:b66: :-? Tenuki.

:b88: Good.

:b90: Bad habits die hard.
Quote:

Re: :w26: in kwinin game.

Local choices: S14, R15, or tenuki.

:w93: Tenuki.

:black: 104 Bad habit. Why do you need this atari ?d

:black: 108 H16.

The score is wrong. ;)

something like that probably

I was afraid of something like that


:b56:- :w57: is this bad? If I play L8 he can just cut me right?

:b64: - :b66: yeah... no comments

:b90: This was not to push without cutting, it was to prevent Q15.

:black: 104 not sure, you're probably right that it doesn't do much.

:black: 110 - 112 , yeah once again you're right

Thank you for all the comments

Bill,

I think it is the game info that are wrong. If the komi is 0.5 the score is B+1.5 right?

The push at R16 (self-reducing libs) can be OK in some special cases, but not here. ( There was a typo in the original post 74 ).

Hey Ed,

I must confess that I played it because it looked like a cool move higher level player would make.


For the game of today, a win against a 12k+. I think I was lucky to win because not everything I played should have worked. Anyway I tried reading every move but I should concentrate to improve my reading because I'm always afraid I misread something.
