Is this one of those times I should check behind on the turn?

[spamuell]

Party Poker 2/4, but it doesn't really matter. 10 handed.

First orbit. I have AA in MP. I open raise and only the BB calls.

Flop TT2r.

He checks, I bet, he calls.

Turn: 5, offsuit

He checks.

What if there was a flush draw on the flop, or the 5 on the turn brought a twoflush?

I understand that you should check here because you're either way ahead or way behind, and you can't fold to a check-raise and you might induce a bluff on the river and he doesn't fold a worse hand (obviously). The thing is, they call with so many bad hands, he may well call the turn with just overcards, so perhaps it's a bet anyway.
