noseki? ladders are good for white. can white play this way if she wants to keep black low on the left side?

development of the bump

the bump (1)

tderz: There are actually some examples (5 on gobase) in Go history when Black is one more to the left (c).
Black has basically two choices: a & b.

the bump (2)

tderz: has to be answered by (not true, there is also a game where White jumps to a), vice versa .
After , White has the normal techniques hanging conection b and the double-hane c as alternative continuations.
Both end in (very local) sente for White.

the bump (3)

tderz: this could be considered a natural continuation for both.
What will be White's next move?

continuation (1) of bump

tderz: After , Black defends at and White can counter-pincer at .

Actually I did not find any professional games with in this position, only if is at a ( is then at c).

### Tesuji

white tesuji if Black tenukies on the left

tderz: If Black does not defends at above, then
here is tesuji.

Inoue Ichiro - Kitani Minoru (09.11.1927)

Yoshida - Ishii
``` Event     Oteai,1974,Japan,
Black     Ishii Kunio, 8p
White     Yoshida Yoichi, 7p
Komi     0
Date     1974-04-18
Place     Japan
Result     W+R
```

The next moves were White a and Black b!

### Pushing through

Pushing through

tderz: If Black pushes through with and cuts at ,
then White can get some grip on , because she is assured of an atari a. Hence white could extend with to or so.

Often black a, white b is exchanged.

### Tewari Analysis

another starting point

tderz: Sometimes, White also starts like this, because she knows about black's weakness around a,b.

tewari - with the two-space-high-pincer, the bump is not advisable

tderz: Black is too far away from the white mini-wall to be efficiently controlled by .
Also is too far away from white allies that the whole procedure would work.

Hence, my conclusion is:

If Black made the two-space-high-pincer, the bump is not advisable.

Alex: I agree with your conclusion. How is this tewari, though? I thought tewari meant analysis by either changing the order of moves or removing superflous pairs (one White, one Black) of stones, neither of which you've done here.

Andy Pierce: follow-up question: if the bump is not advisable, but white really wants to keep black low on the left side as shown, is there a better alternative than the bump, or does white just accept that this achieves her goal, at a local loss?

Rich: The two-space jump keeps black low.

jumping once or twice with iken-tobi

tderz to Andy: as Rich says, if you simply jump, you keep black low (if that is your aim). Also the one-point-jump will do. Of course, Black could also jump to j, that's another story.

After e.g. -, White could exchange a for b, then counter pincer at c .

exchanging once without aji-keshi

tderz: After -, White could slide to a.
It is important only to exchange for , as white-m - black-n would be aji-keshi.
If Black ever peeps at p, then white can connect nicely with q-r-s and Black seems wanting to cut a bamboo (bad shape).

Furthermore, if Black ever cuts some stones off from the center, White still has a sabaki-aji for making life in the corner with White double-hane n.

### Game record

Here is the game record in question:

how to keep black low on the bottom

Andy Pierce: I played thinking to press black low on the bottom side since and are both low. When black played the two-space high pincer my thinking was that I can't really play the one point jump due to , but maybe the lighter two point jump would have been ok. On the other hand I could have approached at a before to see how black responds first.
