Just yesterday I took all the avalanche variations off of my dailyjoseki queue, because I thought "when will I ever use any of this?" Then I had this game :) . My opponent got ahead in the middlegame because I mismanaged a weak group (esp. a good tesuji for black at 101), but I started a successful attack around 170 and my opponent messed up some endgame, so I was able to squeak out a win.

I was wondering about that. I know the usual joseki looks like this:

But after the sequence he played, I didn't see anything I could do other than let it revert:

Any ideas?

In your diagram:

the exchange of 5 for 6 prevents black capturing white's corner very easily.

Since white has neglected to do this, presumably he wants you to eat the corner. I think it is reasonable to oblige.

This leaves white with an annoying problem of attacking black's cutting stone.
