AK catches an A and gets reraised on flop.....

[HoldenFoldem]

my second orbit at the table. No reads from PAHUD yet, as not enough hands played. Villain has the button. This raise to 3 x my bet smells like trips...but i'm relatively new at NL100, having been back down at 50NL for much of the last two months. Given the little bit of info i have at the time of the hand, what do you make of this and how do you play it from here?
