This is a hand i played recently at on Pokerstars.

Have less than 100 Hands on the opponent but he seem to be on the looser side playing 39/24, and he's pretty loose in the SB too.

This is the Hand

Villain: SB (100$) opens to 1.5 

Hero: BB (54$) raises to 4.5 with   Ac Qc 10s 8d

Flop comes  Jh 9s 3s

Pretty good flop for me, I cbet 5.25 and he makes the call.

Turn is a 2s completing a possible flush draw and he all of a sudden leads into mefor 8.5 into a pot of 19.5

First i wanted to bluff ship it cause i really think he wouldn't lead the nuts here this small, but without a blocker i decided to fold.

What kind of hands do you guys put him on, and what would you do in this spot?
