You tell me the move.

[Metnut]

Early in the Stars $100+9 11PM multi. Blinds are at 25/50 and it is a PL tourney. The tourney chip leader has just been moved on to my table and i have quasi-position on him, I'm sitting in the sb and he is button-2. I have about 2450 in chips and the tourney chip leader has about 7500.
I have TT in the sb. It is folded to the big stack who open raises to 150, he is called by the cutoff (has about 3200 chips), and the button folds, action to me
What do you do here?
I call. Flop comes 3c4c7d.
What do you do here?
I check, big stack bets the pot (500), cutoff folds, action to me.
What do you do here?
I raise-pot which is practically allin.
I can give the results if anyone wants them but I'm more interested into how people here would play a hand like this.
