This is the major variation. here was invented by Fujisawa Kuranosuke.

here is now almost always played: the alternatives at a and b are nowadays considered to be inferior. The continuation with at a gives Black too much in the way of outside influence (see below).
There is also Kajiwara's variation with at . There is also Cho Chikun's variation where White plays at c.
Black's tenuki after has been seen in pro games: 3-4 point high approach two-space high pincer, ogeima, tenuki.

The normal moves are as shown here, completing the joseki. For a while the relative timing of the / and / exchanges was considered a critical issue[1], but (it seems) no longer. at b is a variant which is stronger in the corner. The exchange of for is a loss for White, as it greatly weakens the aji of his solitory stone, but it means that indirectly covers the cutting point at c. is of course not played if Black already has a stone in the area.

can be played here instead, provided the ladder works for White. The first time it appeared (perhaps) was in a game between Miyazawa Goro and Ishikura Noboru. Can the latter therefore be considered to have invented the variation ?
![[Diagram]](../../diagrams/37/eef4a0a383206dc6b9aefedb2ad98e6e.png) | Variation (continued) |
As far as I (Dieter) understand, there are two issues in this joseki:
- Will Black be able to make up for the local loss by playing effective ladder breakers for the ladder at a (which obviously works for White, or else she wouldn't play 1 in the previous diagram)?
- Will Black be able to close off with b and cooperate well with the upper left ?
![[Diagram]](../../diagrams/39/80b5bfa983ebaa85794c6e46e879d163.png) | Vulgar |
here is considered vulgar. White seems to end in sente, but if she takes it, Black can play Black a-White b-Black c-White d in sente, completely enclosing White in the corner, The result is considered better for Black.

![[Diagram]](../../diagrams/10/de8741f6374c4f71e9ea1570730906e4.png) | Critical line? |
This is a possible critical line for the supposed timing issue. before is natural, simply because is locally a bad play, weakening the marked white stone (it is only played at all to strengthen White's cutting point). The question is, what if Black now plays to cut, the shape to the right having been fixed by / ?
This position has occurred in a game, Cao Dayuan vs. Sakata Eio 1987-04-27.
![[Diagram]](../../diagrams/7/eeb0f1ca940a89399e7ad364f7f9382c.png) | One critical line |
After these plays and White a, Black b, White c, White has died inside and has much influence outside.
![[Diagram]](../../diagrams/22/298a35e509325b875eacdb773934d679.png) | Another critical line? |
Another possible critical line occurs when White pushes in the centre first, as here; and Black makes the bamboo joint to thwart White's later play in the corner (now if White a, Black b and White has less eye shape). That invites and induces the cut .
This was played in a Korean game (Seo Neung-uk vs. Cheong Su-hyeon 1990-12-07); variations are given in Jungsuk in Our Time.
Dieter: May I point to Deviating From Joseki In Games 1.
I have a question to this variation of the 34OneSpaceHighApproachTwoSpaceHighPincerOgeima?. Answers are welcome.
![[Diagram]](../../diagrams/3/34bc43c82907a5354356a8b37c673679.png) | Joseki or not? |
Is a joseki move? If so, how does White deal with ?

Charles Matthews here is Hashimoto Shoji's move from 1975.
![[Diagram]](../../diagrams/4/d2ee06e4984776ce75bc912d2bf4f729.png) | Continuation |
Now at is usual. Connecting with here did occur in a game Sun Yiguo?-Li Chunhui? (amateurs in the Wanbao Tournament) 1995-01-13, with these plays to follow.

After I expected , , . May be I have seen it as an example in IshidaSJosekiDictionary. Thank you for your comment. Hans
