AQ hand, $475 sat. What are my options?

[PrayingMantis]

Here's a hand that is bothering me for a few days now. It's from a $475 sat to an EPT event. First 9 win about 9K package each. 17 left out of about 200, I'm below average.

The EP raiser was playing very LAGishly early on, making biggish calls too, especially from LP, but since he lost a big pot and the money is getting closer he became pretty tight. He seems like a solid player.

I don't have much of a read about button, he is relatively new to this table. I assume he isn't bad.

I have been playing fairly tight recently, picking my spots carefully. The blinds are going up slowly, and there's a lot of play in this format.
