This is a favorite joseki of mine to play as B when W has support from the corner nearest the kakari stone. However, after I have encountered an "iron pillar" response extending to rather than a hane. It seems like a solid response. B's hane underneath no longer threatens. If B responds with a matching "iron pillar" along the 3rd line, W can take the 3,3 point without fear and B must leave one group under-attended. Thus, the most natural move seems for B to take the 3,3 point. But that leaves B with a single stone contacting a group that may have great possibilities to attack it depending on the board. See through below. Does that limit the applicability of this joseki or is there a better response for B?

The vital point in this shape is . after and , there is a cut at a, and white has no way to defend against it without making an empty triangle. At this point, white has gotten a bad result no matter what follow up.

White is probably best off by simply taking the corner. After W13 , black can cut, but since it is not sente against the corner to do so, it is not urgent. Black should cut if his stones in this area are weak. Otherwise, both players will usually play elsewhere first, and whether black will cut or white will connect remains to be seen.
