Flatting's fine if you don't have squeezers behind and/or have loose passive players yet to act. In general though the more people behind, even if they don't squeeze light, the more likely you are to get pushed off your hand anyways, so the less likely you should be to call in earlier position.
On the turn, unless he barrels an insane amount of the time and/or value bets thinly (ie with 8x/99), I don't see how he doesn't have a hand he's willing to go with. You put Tx in a tough spot as well as overpairs somewhat, but in general people this laggy won't let either go imo.
I'm also not sure about the float if you think he is
barreling that light. Most of the time you're just going to turn a card that you can't do anything on. What about the Ts? Ac? Jc?
