50NL set vs possible straight

[gir]

PF: Fine
F: Fine
T: If you're going to bet, don't look so scared. Make it $10 and for frick's sake, fold to a reraise.
R: As played, you came off so weak on the turn, I'd be inclined to make the call. If your opponent has decent reading skills, he can see you bleeding in pain and on the cusp of completely letting go of the hand.
