With the preflop action I dont think you are going to be too worried about villain just checking behind you, he will be betting here almost always. What happens if he just calls your $5 bet on the flop? You are in the same situation just with less money. If you are going to bet this flop then it really cant be for anything less than a push, your stack is barely bigger than the pot. Considering the stack sizes I really think a checkraise/AI is the best line if you think you are ahead most of the time.
