50NL, marginal play w/ AQ

Villain has only played 8 hands but has a VPIP of 100% so far. Is this standard? Bet more on turn to set up river shove?

I always donk the flop like 3/4-psb. Lead the turn and probably stack off. The problem is this limp min 3 bet is either full of shit or a big hand. Really though the only hand that I'd worry about is AA but still I'm staking off here.

when he calls the turn I might just c/c the river maybe

this is a tough hand
