Your chances of being ahead aren't really all that good, your outs are sketchy, and getting raised here would kind of suck, since you probably don't really have the odds to chase against Villain's raising range but you will sometimes have a full 6 outs.

Check-calling is kind of asking to be taken to Valuetown, although you will occasionally be up against 7d7h or AdJc or something and induce a semibluff.

Check-folding induces a bluff or semibluff and then rewards those plays.

In short, you have no good options.

I think I'm leaning toward either a check-fold or a check-call (I can't decide which I prefer). One annoying thing is that the river will again be awkward if you check-call the turn, but, like I said, I don't see any good choices.
