Villain Makes a Fishy Play

[Roy6]

I often find myself in this situation and I'm never good here.
If he has something (not JT), but 2 pair/set, the flop check is really awful. However bad players make bad moves.
It sucks to call down in this rather small pot and see his AK or KQs.
You have outs to improve so if want to SD just check-call turn (now even 99 beats you badly).
If he's on 88 or TT he's drawing very thin anyways.
