Set on 4-flush board against shortstacked donk

[PoBoy321]

Villain's been playing on a couple of my tables. He's loose pre-flop, passive postflop and basically a donk. He only has 1/5 of the pot left in his stack on the end, so do I put him in, check/call or check/fold?

UTG ($4.05)

EDIT to remove river action.

Put him in. You are calling if he bets. At least take the miniscule amount of fold equity you get by betting.

Pot flop, hoping to push the turn. You're caller only has $5.50 left on the turn, just a touch over pot, so get him in right there.

Yeah, my flop bet was a tad under because that's what my standard CB would be in that situation. The turn bet was also small because I wanted him to feel pot-committed on the river if he was calling gme down with KQ or something.
