Life In 19x19

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 , 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 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.

For , do you mean this move is fine...

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

For at R3, I thought of that

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

page 28 dia 4 (or at least I think this is the same)

That's a different shape.

Hi Laerthd,

A5 format and it is not so handy to have with me.

I can see it's kind of big.

(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.

Hmm. Good question. Not easy to answer.

Hi Ed,

That's a different shape.

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.

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

Hi Laerthd, are you looking at the R3 cut, ?

The book diagram is a completely different shape: there's no cut at R3 (a) !

My bad, I wasn't really clear. We are not looking at the same group I think.
I was looking at the black group in both situation.

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

So maybe not that similar ^^'

Hi Laerthd, Thanks for explaining. Yea... they're different.

Hi Laerthd,

Game v. kwinin,

OK.

o4, etc.

R4.

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

S8+Q8 sitting there, to fix your shape.

Did you miss S8 ?

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

o4, etc.

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

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.

Bad habit if you're not going to cut -- just 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,

R4.
Is this because with Q3 I lose sente and will never really get the opportunity to make my wall useful?

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

I played there because it was facing the largest side.

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

Hi Laerthd,

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

( Pushing on top directly at , instead of , 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,

B2.

What was your plan if W haned D7 ?

Why not cut and fight ?

L4 is the big fish.

F8.

K7. L4 is the big fish.

- This exchange... Maybe L8.

o2 or P2.

Tenuki.

Good.

Bad habits die hard.

Ok I take not to play R5 from now on.

Re: in kwinin game.
Self-reducing liberties move.
Local choices: S14, R15, or tenuki.

Tenuki.

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

108 H16.

110, 112 Why ? Bad habits die hard.

Ok I take not to play R5 from now on.

( Re: Self-reducing liberties moves: )

Quick comment on the last game.

The score is wrong.
