The central shimari. Did you try it before?

I had a lesson on KGS few hours ago with 12-kyu, who likes high moves around
tengen. I was suprised, that he played lot of soft moves after tengen. It's not logic,
I think. He explained me his standard idea later:

"For tengen I have usually secured one side of the board and then start massive invasions
based of tengen and close cutting points"

It's an interesting strategy, but it's more common to use high stones for attacking.
I showed him this example - my favorite one.

Black used his central stones well! Both of them were so useful!
