A college tournament hand

The tournament is a free tournament sponsered by my school. The top 3 or 4 get a free weekend trip to UNC Wilmington to play in a poker tournament there. Also the top 3 get bracelets. We are now down to 5, so no one is playing like it is a free tournament anymore.

UTG:~300000
CO:~100000

Hero:~200000
BB:~150000
3000-6000 blinds

Turn:4 [img]/images/graemlins/diamond.gif[/img] Hero checks, UTG bets T12000, Hero ???
UTG been TAG and been raising preflop more than limping. My table image has been very TAG, and more towards the tight side than him. Though I am usually LAG, he has not seen me bluff once. Even though the free trip would be nice, I want the gold bracelet for first even more.
