3-4 point high approach, keima
This choice of is very steady. Usually Black isn't planning any complex variations here, but to keep sente and create a solid position on the left side.
For pro use of this joseki, see the keima joseki in fuseki.
After that Black at a is the standard play. The pincer at b is quite a new development in joseki (though played by Takagawa 50 years ago). Occasionally Black plays at c, but this leaves an obvious weakness and bad aji near a. Black tenuki at this point is rare. (An example appears in one of the games in The 1971 Honinbo Tournament book. A rare case in which knowing a pro play can be detrimental.)
For White tenuki now, see 3-4 point high approach, keima, tenuki.
After , the main line here, an extension to one of a, b and c is expected: which then ends the joseki. It seems that the tight extension at a has become more popular than c; the play at b will be made in connection with some overall consideration. White directly at d is also seen.
After White commonly plays into the corner with
, and
gives Black some sort of development on both sides.
Andre Engels: I cannot find any extension like in my game collection. Black either connects at a, or plays tenuki.
Charles Two examples I have (Gogod) are Takagawa games from 1954 (as old as me). A recent one was Yoda Norimoto-Kobayashi Koichi 2002-02-18 in the Kakusei final.
Nick Hoover: 3 is another reply for black that seals white into the corner and emphasizes the outside. 3 games on GoBase have this pattern.
If white resists being sealed in and plays 2 at 3, then black can play 3 at 2 and white is left with a group without a base.
There is also a fighting line, set off by . After some moves on the outside, Black goes back to a to live in the corner.
After this way,
is normal. Possibly White plays at a. After that an extension along the left side is very big for Black.
transposition: BQM 246
rokirovka: I played this joseki twice as White recently at the 18-19k level, and both times Black reacted with . I transposed to hane at the head of two stones with
, Black played hane with
, and I stretched with
, happy to let Black push along the 5th line as I push along the 4th line. Is this the correct play for White?
From here the two games developed in very different directions. In the first game Black backed off and played at a, I extended to b, Black replied at c, and I played elsewhere.
MrTenuki: is usually a mistake. According to the Haeng-ma Tutorial For Beginners,
is what Koreans would call a Ja Choong Soo (literally, "self filling-up move"), a bad move that reduces liberties. Assuming that there are no other stones around, your
and
should be sufficient.
