Hi,
Since we know nothing about the players i think bet/folding the turn is fine i'm sure bad players are calling 9x again almost always, if you get raised you're clearly beat, it's a lot easier to play then if you check behind without knowing what to do on the river.
If they're rather taggish players you might be better off checking behind and valuebetting 2,5-8,T,Q rivers because they'll often fold stuff when you barrel the Q, but they might look you up on the river if it looks like you don't have it because you checked back. Since they're usually not good enough to valuebet even 9x on the river, i think you can fold if you get donked into barring a read that he can bluff there.
Hope it helps.
