Hello mylove190207,
Flop: Well, I don't really see any reason why we should slowplay there that long.

Rather just Bet yourself on flop and build it up, I would even consider doing it pot size. If they don't have a Qx they wont pay you much either. Plus you are OOP.
As played
Turn: Well, kinda close as well, other option would be to donk yourself to avoid them Checking behind for pot control or anything similar. You don't want to see that. That's also the reason why you should just pick Bet/Bet/Bet line rather than Check/Call and Check/Raise or Check/Call turn.
As played
River: Could easily even bet it bigger. But overall obviously just start betting right on flop, if they don't have a hand then they wont pay you anyways much while the turn wont change much if everyone of them Check behind.
Best Regards.
