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 4-4 point, double low approach, kosumi.
Black can also tenuki again-- see Joseki-related life-and-death Example 4. However, Black will usually react to White's double kakari, because it is considered poor to allow the shutting-in play. (After a White play at b, Black just barely lives in the corner while White gets superb influence.) See 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. -- Charles

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.
