4-4 point low approach low extension, slide, pincer, 3-3

    Keywords: Joseki

This page is in need of attention.
Reason: major variation - directly attaching with B4 - is missing

Main line  

W3 at a for corner. See below.

W3 at b is complicated. (4-4 point staircase joseki).

Main line  

These plays are still the main line, though increasingly B2 is played directly at B4. White plays W5 for ladder aji.



After these moves, Black needs a further play here. If the ladder works Black can play at b (and then will need to capture shortly). It seems, from pro games, that this is a subtle discussion:

  • this variation is played even when the ladder is bad for Black, and Black must play a now;
  • even if the ladder is good for Black, Black may anyway play a.

Naturally the evaluation of the position after Black at a must depend on the prospects in a fight if White's cutting stone escapes.

On the left side, black c might be a useful sente move, answered with white d.

turning in  

Just like when black+circle is high (see 4-4 point low approach high extension slide pincer), W1 is still possible, but the further variations are completely different. After W3, in this case the usual move is B4 here. The following moves allow little variation. In particular W7 at W9 (black answers B7) and B8 at B0 (white answers W8) are bad. After B0, white has two choices.

For the main article regarding W1, see 4-4 point staircase joseki.

Continuation (1)  

W1 is one possibility. White takes corner territory while black gets strong influence. After B2, white usually plays elsewhere, but later she has W3 to W7 as a large follow-up.

[Diagram]
Continuation (2)  

If white wants to avoid giving black so much influence, she can play W1 here. However, white's corner territory gets much smaller too - in fact, she even needs another move to be certain of two eyes.

Black connects  

B4 is possible as well. After this, white will connect under with W5. B6 at a is not good. White answers at b, and black is in problems. Instead black plays B6, after which the moves to W9 are most common. Note that in this variation, white rather than black takes the upper side.


Omitting B2

Omitting the exchange B2-W3 in the mainline, Black proceeds directly w/ B4
