This is a bad habit that I had when I started the game. The idea is to defend the corner in (almost) sente, even if white attaches, to avoid the annoyong 3-3 invasion. According to Eidogo joseki tutor the stone sacrifice is a Lee Changho idea.
I'm suitably impressed. But this type of "pattern" is more often disadvantageous than helpful.

By "pattern" I mean sequence, order of play, not "shape".
Fllecha, a study suggestion: can you find this strategy/pattern lurking beneath the surface in AlphaGo vs Lee Sedol game 2?

Clue:
It would have been a nice idea for AlphaGo, so Lee varied to avoid it, but AlphaGo came up with a nice counter to that too.

White missed chances to invade the bottom left corner. I am evaluating some positions based upon it here: http://www.lifein19x19.com/forum/viewto ... 33#p204833 :)
