I like betting the turn because it's a scare card and you picked up equity. After he bets $3.50 there's less fold equity and if he has a made hand you're at best a 2:1 dog. I like bet/folding small ott, expecting to rarely get raised, folding out overs and some small pps, and setting a good price for the draw. As played I'd prefer calling, you're getting about the right price to draw to 10 outs, not to mention the nuts, and there are some implied odds. I don't think the shove folds a J which would make it bad.
