Hand from Tulalip $100k guaranteed

[elena_elphie]

It is the fourth level of the tournament. Blinds 100/200. I have around 5500. The table has been fairly tight and tough, I decide to make a steal attempt by raising to 600 from late middle position w/ T8 of clubs. One cold caller who is pretty reasonable with a similar sized stack.

The flop comes T74 all hearts. I bet 600. Villian looks down at his cards, obviously checking to see if he has a heart. I don't think he is acting. After he is done looking he raises to 2000. What is your plan from here?
