AQ flops TPTK on somewhat drawy board and checks behind turn

[TheBobn]

Anyone bet the turn here for value? That's a pretty bad card for my hand even though I picked up a gutshot. Against a villain capable of checkraising with a draw here, does anyone like checking behind and picking off a river bet/vbet?
I'm trying to mix up my checking behind on the turn with marginal as well as strong hands to seem less transparent.

Anyone make a small raise on the river for value?
Villain is 75/10/2/2.5/8

I feel like b/f is pretty similar to checking behind the turn here and calling or vbetting river.

Normally I'd bet this turn but I want comments on this play as to keep the pot small, especially given the fact that if we bet the turn, given his stack size, we are near pot committed by the river.
