Played in the V-Point Freeroll last night.
I'm not sure if I played this right

and was hoping for some thoughts!
My hand was QQ in mid-position... folded to me. 30 players left.
I had 9K and the Blinds were 1200.
I raised 3xBB and had 1 caller - the big stack

with 50K - sitting behind me.
Flop came 3 clubs - 8, 4, 3 I think...
What should I have done next?
Was my pre-flop 3xBB raise enough?
