($33) AQs facing large raise 5-handed

[ebaudry]

What would you do here with AQs? I normally resteal vs. a smaller bet, but he put in half his chips, so presumably i'm not going to push him off the hand. I assume I'm ahead, especially since there's a higher than normal chance that he's on a tilt-raise. But even if ahead, should i be gambling that many chips without a great pair?

I had a little bit of a read on the raiser since the second hand pasted below occured immediately before the one here.
