Another river decision..

[mongidig]

20-40 live 9 handed. I have TAG image

UTG limps(TAG), very loose player calls in mp, folded to SB(pretty loose preflop but does seem to be a thinking player) who calls, I raise AhAc, all call.

The flop: QhTc4h

I bet, UTG raises, loose player calls(he will peal with anything even if raised), SB calls, I reraise, and all call.

The turn: QhTc4h6h

SB donks, I raise, all fold and SB calls.

The river: QhTc4h6hTs

SB checks, Should I bet or check?
