Villain was kinda loose, not too aggro.

From the flop, I thought the villain was on a draw. The turn made me think that he was might be playing his Ks, but still drawing, maybe to a straight but also a club flush.

The river basically sunk me... anyway, he flipped over a Q J. Was there anything I could have done better? Pushed harder on the flop? I figured a smart player with a made straight would re-raise to get the flush draws out, but there are a lot of stupid players, so I can't rule it out.
