AA faces turn c/r, 3/6

hi,

i didn't get used to bluff and semi-bluff turn check-raises at low limits, so i'm trying to adjust since i caught a couple of 3/6 guys taking shots...

opponent here is 21.5/11.5 after 90 hands. his ag. factor is 1 so far. only thing i remember from him is stealing in button with Q6s.

i think he might limp a lot of medium suited connectors here... pp>77 unlikely

without more reads, do you call down that scary turn? call and fold a non-pairing river? fold?
