Put yourself in your opponent's shoes. It looks to him that you do not have a queen. You will usually call with either a better hand or worse hand if he holds a set. You will not bet if he checks with a worse hand. His bet is probably with a set given the betting and you can beat his set. I don't think he'd reraise preflop with QT, but he will with a big PP. Given the turn check-raise he must have a set or QT. I think a river raise, although risky, is profitable. If 3 bet I'd call on the river. I feel the critical point of this hand is the turn check-raise. Given the fact that he reraised preflop he must have a set. You can beat his set and therefore should raise on the river.
