The high approach to the 4-4 point at is usually played with the intention of setting a framework on the right of . One characteristic of this high approach is that it tends to give black a sizable amount of fixed territory.
A common answer by black to will be a.

is one common play. and aims to reduce the corner territory, and then followed by or around the region of a to build up a framework. If there is already a white stone at a, is sometimes played at b. Because of the monkey jump at c, white's territory at the top cannot be said to be large.

The other usual joseki is and . Black gets even more territory at the expense of making white very solid outside. If there is already a white stone at the vicinity of , then may consider playing at a point around a.
BobMcGuigan: I'm not sure the sequence shown in the previous diagram should be called joseki. The problem is that Black's territory in the corner isn't secure and White's stones on the top have been strengthened. And there is very bad aji in the corner, for example:

There are many variations after but the best black can do is get a ko or else leave very bad aji. Here are some illustrative diagrams:

![[Diagram]](../../diagrams/25/d2b646cd9389d6dc4c4a9f25fc7280b0.png) | Not much better |
Now a white move at a looks troublesome.

After White has the aji of the moves a through e and Black may prefer the results in one of the earlier diagrams.
So I doubt that the attachment underneath is really a joseki unless the surrounding position is right.
- Velobici: It may be that the attachment underneath is a misapplication of the well known 3-4 point one space high approach joseki. In that joseki there is less room available to White should she decide to invade the corner, as a result Black's corner is secure.
In my opinion the proper joseki is to respond to the high approach with a one space jump as in

If White strengthens herself, as in the second diagram on this page, Black still gets a lot of corner territory, with no bad aji. After attaching underneath it would be bad for Black to remove the aji of the move at the 3 - 3 point right away as that would be gote and White would have been strengthened.
Sanz: I saw this type of "punishing move" in a book. a would also work.

IaGo: my dictionary suggests this, with a possible extension at a, and at being possible depending on ladders...
It seems a little more secure in the corner.
Charles I don't see any examples of this by pros.
How about 6 at b to make the ThreeCrows? Too overconcentrated?
unkx80: Thanks all for correcting my misconceptions on this joseki.
