3-4 point low approach two-space high pincer one-point jump

    Keywords: Joseki
One-point jump  

This play for White in the 3-4 point low approach two-space high pincer was hardly tried before the 1960s. White looks to settle himself; but there are variations involving a difficult fight.

Black's common reply  

Black at 1 is now expected - the alternative is Black a.


This is the set continuation.


The main ideas now are Black at a, permitting White a slide on the top side, or b denying it. Also played are Black c and d.

Tough line  

If Black 1 here, White in pro games has tried a counter-attack on the left (one of the points a), or at b to take a key point of shape. It seems there is no definitive joseki yet.

If Black omits B1 ...

not only defensive move  

tderz: If Black omits B1 above ...
then W1 could become the biggest move despite being on the 2nd line. It is big because it is flipping the defensive/offensive properties (I would like to formulate this better) of the group. Often it could be considered an urgent move (I think there is an example in Yang Yilun's Fundamental Principles of Go).
black+circle becomes a little bit meaningless.

Bill: IMO, after W1 you can consider black+circle as a kikashi stone, inducing the low W1 instead of a normal extension.

tderz: Good idea indeed! White is quite low and black got an additional move. It must be the specific position, which makes the difference between B1 above and W1 here bigger.

Bill: Well, I'm not up with the latest on this joseki, but my references do not show W1 in any variation. <shrug>

From the side  

W3 from the side is a major alternative. White wants to stop black from extending along the left. Usually white will have a position in the lower left to back this move up.

Black keeps the white stones separated with B4 and B6, after which there is a turning point.

Attaching in the corner  

White can go to the corner with W1. Black can play at a, keeping white out of the corner but allowing him to strengthen himself, but black can also build thickness with the combination of B2 and B4 in this diagram.

This same joseki with white+circle at a has also been experimented with.

Pushing in the center  

If white pushes in the center with W1, black can still develop the top with B2 to B6. After this, white is unlikely to attach at a right away, because the cut in the previous diagram is now too painful.

Taking the corner  

Nevertheless, black will often secure the corner fully with B2 and B4, allowing white to claim the top with W5.


One move amateurs are prone to play which is actually bad, is pushing with W1 here. Even though white might be building up thickness for an attack on black+circle, pushing black along the fourth line like this gives up too much.
