4-4 point low approach, attachment, wedge

[Diagram]
Wedge after contact play


This is a deviation from the tsuke-nobi joseki (namely, W3 at a, B4 at b) which is possible for White when she has a ladder-breaker in the opposite corner.[1]

Migeru
I think B4 at c is Black's best option because White will want to play there next in any case.

The ladder variation

Charles Matthews The important ladder occurs after B1 and B3. White should expect this and use a ladder with W4, unless White is already strong on the left side in which case White at a may be possible.

The ladder variation, continuation

The expected sequel is then B1, W2 (because of the proverb take off stones captured in a ladder, at the earliest opportunity


[Diagram]
Playing a local ladder-breaker

With B1 here, Black prevents the ladder capture: clearly though White at a next means White can take over the corner for a big exchange.

Crawling fight

If White isn't so flexible, and plays W2 here anyway, a difficult crawling battle can arise after W4. There are some more ladder tactics available after B5 (double threat ladder-maker).

Atari the other way

The ladder line above is normally good for the side with the favourable ladder, so in practice B1 here on the other side is usually seen. After W2, Black at a is the normal joseki, while Black at b leads to a difficult cross-cut fight after White cuts at a.

Joseki

The usual continuation proceeds with B5 double hane, and White taking the corner. Black has good outside influence and can take more with Black c, White d.



[1] This should just be, when White has a favourable ladder. Charles
