I think you can open up your range to include AJs and possibly KQs here, but A9s is not enough hand to handle that much heat, even if much of it's likely to be "fake."

Think of the raises in front of you as 2.5 sb. In other words, your range should be somewhere between what you'd play for two bets and what you'd play for three bets.
