Re: Big Brother Malkovich # 1 (continued)
I'm unlikely to drop by again before Tuesday, so here's a trigger. If Shape and Aji approve,
So you've got an eye?
That don't impress me much

Just to make sure that everybody is on the same page, the position is this:
...and we are waiting for Violence to express an opinion on the marked stone.

Pro opinion of move 67
Back on move 67, Gresil played this:
Topazg changed it to this:
I thought that this was also a mistake, and posted this:
Nonetheless, Violence approved the move. This greatly confused me. So while I was at congress, I asked Yilun Yang about the choice between the two moves. He said that neither was best...
For Topazg and observers:
...but when I persisted on an evaluation of the two moves, he said that it was best to let white's middle group run south and not try to cap him with K8.

My guess is that Violence will happily pay 1 stone to do this:
For beginners:
Lets look at the plans and goals and direction for each of the five groups that are involved in this fight.
1) This long group has at least one eye in the middle, and can easily make another over on the left side ( these areas marked with squares ). It has no defensive concerns. Offensively, it wants to split the two white groups that don't yet have eyes. The gap though which it must push to do this is big, and cannot be closed by white for several moves yet. So this group is in no hurry to act, either on offence or defense.
Capping, as Topazg wants to do, while not a bad move, is a low priority move played at the expense of higher priority moves.
FWIW, a secondary direction of play for this group is sliding into the corner because, if nothing else, it is a corner. It may become a higher priority if the white group in the lower left starts needing the corner for eye space.
2) This group has no eyes, and is running. Its direction is primarily away from the strong group to the west, trying to enclose the eyeless black stones to the east. A secondary direction is to go southward just to stay alive. It does not really want to run southward, as this means running along past an enemy wall, but it will do so if it must to stay alive.
3) This black group has no eyes yet, but can get them in gote if necessary ( around the area marked with the squares ). The fact that J19 is sente to kill the white group to the west gives black just enough room to do this. Making eyes in gote is not desirable except as a last ditch measure.
This group is just barely behind the sector line, and would like to get out, as doing so threatens both of its neighbors. It is probably best to go out between the white groups without touching either, so as to be equally threatening to both, thus keeping white uncertain about where to defend.
4) This white group has easy life in gote around the area marked with a square if it has first play to get to L18. Moves like Q15 and P14 may help, although they are aji-keshi.
When living involves aji-keshi and/or losing sente, it is a last ditch alternative.
The best play for this group is to run out to the south, threatening the black neighbors to the west as it runs.
It would also like to interfere with black's potential to make territory along the right side ( in the area marked with the triangles ) by getting there first. But this is a distant fantasy.
5) This group already has eye space ( in the area indicated by the square ) and can make territory going southward. Doing this also endangers the white group to its west.
Summary: so when all five groups are examined, we can see that black has three groups with the following directions of play:
The leftmost and rightmost groups have eye space and are not in danger of being surrounded. The middle one has no eyes, and is behind the sector line.
Furthermore, playing from the left group encourages white's neighboring group to play in the direction that it wants to go. Playing from the middle group impedes that.
Black's play at M11 is a no brainer, IMHO.

This is interesting, thanks very much for posting it - did he explain why?
I mean, judging on his choice of move, my gut feeling is that he feels that top right White group is really attackable, so chasing the middle one out would make contextual sense, but I'm guessing at his reasoning - did he provide any?
And did he pick M11 as the way to do it if it all? Because to me, M11 still just feels slack

Sorry. He did not elaborate and I did not ask. He was just passing by, and I felt that to persist would have been rude, for it was neither scheduled or paid for.

Yup, made it here on the 9th, we've been settling in, even got a chance to swing by the Corvallis club amidst all of our settling in. (I even have a rival in the form of SeJoon Park, which is pretty awesome) the Corvallis club has a great relaxed atmosphere and on the whole, it's a good place for go. Also swung by the Eugene go club, which I might attend occasionally,
Tactics yes, Tact no...
