the answer lies in this statement

If you were the villain here, would you make the same moves throughout with a hand like AQ? The answer better be no because the story doesn't make sense. He either has complete air (which is a tuff buy considering his stack size UNLESS you notice he has been bluffing all day) or a monster (at least tied with your hand, and god help you if he has AK hearts here). The only other hand besides a set that would make sense would be KQ or QJ hearts, and even then you may want to consider folding because the bubble is at stake.
