schawipps messy games
Posted: Fri Jul 05, 2013 2:23 am
I played the following game on the wbaduk server yesterday evening (and used the method desribed in http://lifein19x19.com/forum/viewtopic.php?f=10&t=8637 to extract the SGF...).
As often on wbaduk, I tend to get involved in messy fights, and there, even 11k players handle them quite solidly. In this game, I misread a Ko in an early fight; by patching the remaining groups I got significantly behind. Later, I succeeded to establish a big invasion into the black san ren sei area, however it did not fully compensate my losses before.
I added some questions and remarks and would appreciate any comments and suggestions for improvement!

I'd prefer something like making the chinese formation at the left and invade sanrenseí if he takes one side. With this approach you strengthen his sanresei. But this can be a matter of style
Pincer! his potential at top isnt that great cause of your group and your 3-4 stone is strengtehed.
Your potential top is gone. Just live with your corner stones and attack his approaching stones. maybe c13.
Better strengthen your middle stones with something like N15 to prepare for an attack by the top group. Thjen you can still strengthen them with some shape move in the ceenter to attack the top group yourself later or take a big extension at bottom.
attack the top group. E12 for example.
I thought about R13 to counter the slowness of R 14 and if he tenukies i take the corner with q 17, which also threatens some invasion at his top, but there is a big fight goin on at R 12, so I dont know. Maybe your R12 alternative still is best. The problem with your move: He has to reinforce his top someday anyway and you force him to do was has to be done. and even as you do: Your high extension at 
afterwards is of no value as there is no attack goin top. Play this one low to secure the corner better. 
better approach the other corner I'd say. If you want to play locally here try somethin like Q3 and the josekis following. the standard approach gets heavy easily now as you painfully discovered.
much better
I wouldnt call your J 4 group weak because you got D5 still goin
and 
I think you can tenuki, as your second line stone stops the invasion's connection at R15, at least as i read. Still a bit risky. Big moves: M/L7 D5, leftside
The joseki answer is D6. Look at these josekis at Josekipedia.
L9: this is the decisive moment of the game, but actually I'm too weak to tell you right play here. What happens if he cuts at N9? You could sacrifice and march the way down the M line. what if he just extends or counter hanes? Your sacrifice still would work, if you don't defend the cut. I can't say if the sacrifice here is good. You sure can keep on attacking his group and he gets about 20 points. Were you willing to sacrifice ?
Can you really tenuki ? I can't see a good attacking move for him, I'd try to run more as black.
This one on N6
Do something for your dragon. Everyday. I would have played F10 or M11.

. On the other hand, by abandoning O3/O4 I would get more freedom to take big plays elsewhere...
