4-4 point low approach low extension, slide, outside attachment
One of ideas after 4-4 point low approach low extension is to 4 instead of more usual a. I was rather surprised when I first saw it played against me, but if Sensei's Library says it's a joseki, it probably is.
For a 10k like me, two answers seem natural - a and b.
After white b, black at 2 seems obvious, but it's still not a finished situation. What now - c, d, e, or something else ?
The variation a looks rather weird, so I'm not going to continue with it.
Alex Weldon: This page's name needs to be fixed. "3-3" shouldn't be in the title. Just 4-4 point low approach low extension, slide, outside attachment or something.
Right, I just followed the link from 44PointLowApproachLowExtension and didn't look at where it led.
