What about the corners? The 3-3 invasion in each of White's two corners is actually a tricky life-and-death problem. But consolidating in the centre is (a) smaller, and (b) possibly an negative if you want to invade later.
Would be more logical to close the lower left corner, which is more open.
This is larger than many of the previous plays, which were small. The endgame on the edge is bigger. The lower left beckons, though. See http://senseis.xmp.net/?AllAbout33PointInvasion%2FDiagrams, the "ogeima ogeima". I thought that was called the "dragonfly".White 104: Both players should study endgame tactics!
