at a for corner. See below.
at b is complicated. (4-4 point staircase joseki).
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;

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

is one possibility. White takes corner territory while black gets strong influence. After , white usually plays elsewhere, but later she has to as a large follow-up.
If white wants to avoid giving black so much influence, she can play here. However, white's corner territory gets much smaller too - in fact, she even needs another move to be certain of two eyes.
is possible as well. After this, white will connect under with . at a is not good. White answers at b, and black is in problems. Instead black plays , after which the moves to are most common. Note that in this variation, white rather than black takes the upper side.
