I wasn't sure I could kill it, so I didn't try really hard. I looked at it after the game, and thought others might want to try. No solution from my side.
Game is attached.

A fantastic set of 9 black stones, in a double Tee formation! :P

Actually, I meant the White group at the very top. I've made it clearer now.

White's alive, no?

EDIT: Actually, it seems the top one is dead - there's lots of local aji though. Maybe better is:
