50nl bvb - bad turn card?

[starkwired]

Wow, this is a real tough spot. My initial read is that he's shoving a semi-draw, made hand (JT?, As9s?). I don't know if you can stack off here though. If he's a quality tight player I doubt he'd have called you with an under gutshot on the flop (unless it was 7s6s). I honestly don't know what to do here. I'd probably suck it up and fold.
