Raise the flop.

couple things, its not gauranteed that the same dude is going to bet again on the turn. people always assume that, but its not always the case.

also your hand isn't likely to be much better on the turn as it was on the flop. sure there are a lot of scary cards that can come on the turn, but not so much that you still shouldn't raise this flop.
