From post 45: Quote: 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. Quote: 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.

Hi Ed,

Quote:

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.

Hi Laerthd, are you looking at the R3 cut, :wc:

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 :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, 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 ?

Post subject:	Re: Laerthd study journal
Thanks for the comments Ed, I think I'll learn something there because I don't really understand your moves. Quote: o4, etc. What do you mean by that? Is there a typical sequence here? Quote: 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: 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, Quote: 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. Quote: 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.

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 :w1:

peep from yourself as an option, in the future:

but you keep the one liberty. )

Re: Laerthd study journal

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.

Hi Laerthd,

Quote:

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 ).

( At these levels, quite often people push at R16 as a bad habit. )
Also, W cannot wedge at Q15 anyway ( there's no wedge for W ):

Re: Laerthd study journal

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.
