a little help with this position

dedroid · #1

I think I've seen this somewhere on here before, but can't find it.

I've had this position happen in my game, and I'm not quite sure how to handle it.

I answered at a, but I now think that b is better. white may be able to connect under, but black can keep white low and short of eyes. Is this correct? or is there a better way to handle this?

"a" gives up too much. "b" does not threaten to separate the White stones.

B is the proper way to respond, A is the incorrect. There is a full analysis of this position in 100 Tips for Amateur Players II by Yoon Youngsun.

Or maybe 'a' first. But white will live inside of black's area of influence.

Small, small, small, small, small.

I would cap it with a keima. Is that too mellow?

Seems basically the same as R10 but unnecessarily...well, yes, mellow. Since you can block white strongly with R10 without problems, there's no need to play R11.

Hm, whole bottom right, massive thickness into the center and White lives small and is sealed. I don't see a big loss for Black.

will result in :w2:

which is a bad play for black.
if black can not catch this group he will lose too much.

If you are talking about the analysis on p. 163, I think there may be a difference here, which is that here there are other white stones near enough to be helpful in some lines.

I remember asking a similar question about an invasion on the second line directly under a stone on the middle starpoint in a san ren sei opening. I am not sure whether that was on Go Discussions or here.

In that situation, like in the example 100 Tips for Amateur Players II, there were no friendly stones around (i.e., it was an invasion of one stone on the second line beneath a stone on the fourth line). Someone (maybe Bill Spight or Araban?) suggested that the normal response was to play a butting move against the invading stone, but that it depended to some extent on the surrounding stones.

Dusk Eagle · **#15**

I think the butting move is good if the stones are a line farther back. There's a noticeable difference between these two positions:

So far, I think Bill's suggestion for this situation is best:

If it seems unsatisfying, that might be because in the top right corner, the exchange of :wt:

for

is much better for white than for black. When white plays :w1:

below, black should hane:

Another play you sometimes see in this kind of situation is :b1:

on the second line. It seem kind of loose for this position, but is worth considering.

lorill's question about how to answer White's crawl is a good one. OC, the first thought is to block, so maybe that is the point to play at the start.

If

cuts,

is good, threatening "a", which is difficult for Black, thanks to the marked White stones. If :b7:

,

is annoying, as is "b".

It would be nice to hear more from Magicwand about how to handle this slide.

After reading Dusk Eagle's post, I noticed I confused the position with the one, where Black has the stone on the Hoshi point ^^
So, maybe no fight, fight, fight : (

a little help with this position
