Sucker end of the str8 facing river push, what to do?

[Fractured_simile]

villain in this hand is 46/10/2, so not great, but hasn't shown any inclination to go after unraised pots up until this point. This hand comes up:

Is three betting him on the flop the right play? i was after info more than anything, reasoning i could probably fold out a better str8 draw, maybe keep two pairs or a set, fold to a push.
Hows my check behind on the turn? Should I call this push?

flop is fine. turn you can bet. river is now an easy fold

Bet more initially on the flop. Make people call a PSB with their strt draws.

Flop: Bet more, 3-4. 3bet ok

Turn: Bet/fold

River: As played, fold

Thanks guys,

for clarification, if we're betting the turn, how much should it be?

Edit: The only reasonable i can think of that we beat on the turn is a naked ten, remember villain is not prone to spewing in these spots to date. Is betting really so standard?

id do 26

Yeah I like the bet/fold line on the turn, as played river is pretty easy fold.

i faced this basically exact same hand in live cash game faced a huge bet of like $40 on turn and dumped the kid only had a set but can never be too sure definitely will be re-raising the flop next time
