4-4 point, double low approach
When White makes a kakari to the 4-4 point with , it is common for Black not to answer in the corner, but play tenuki (or make a pincer on the left side).
If White gets to play a second move here, the most usual choice is a second kakari from the other side with (or a). Such a position is called a double kakari.
Black a is the most common way.
Black b will most likely lead to a black wall. See 44PointDoubleLowApproachKosumi
After White makes a double kakari, Black will usually react, because after a White play at b, Black just barely lives in the corner while White gets superb influence.[1]

Evand What are the standard continuations if Black plays tenuki again and White plays b? Under what circumstances is tenuki there a reasonable play?
Charles See discussion on the J groups page, under 'Practical application'. But it is considered poor to allow the shutting-in play. Cf. BQM 48 for cases where Black has two pincer stones on the outside but still wants to be a move ahead in the fight after being shut in.
firstian As a beginner, I'm always looking for the "meaning" of a move, so I can think about whether a move makes sense or not, and also how to respond when my opponent doesn't play a book move. I think I understand that either a or c are meant to separate the two stones and develop on one side. What about the meaning of b? For example, in one of my 9-stone handi game, W played:
I think the correct response to is a. But not knowing what
is suppose to do, I have no clue how to develop my corner group. (My guess is that
helps B runs out to the center, but is that it?)
20k guess: leaves two possibilities - live in the corner, bigger than if
hadn't been played (eg with 3-3), or run into the center (eg with b). In a nine handicap game, black probably isn't clever enough to tell which is better. Therefore, treat them as miai and play somewhere else.
