I don't like this spot. I might lean toward checking and seeing what happens. SB seems tight from your description, and this isn't 6 max where an UTG raise doesn't mean a top 5-10 hand, and the SB would continue with any overpair. I think we are behind way too often here, and SB is checking because he is fearful of BB and the 4 to a straight, not because of our hand...
